    Ammonium Sulfate

    Ammonium-SulfateAmmonium sulfate is a very important fertilizer for any kind of soil that's high in pH and needs a little bit of sulfates to work against the high calcium or the high pH. The nice thing about the ammonium sulfate is that the nitrogen in it is a little bit slower releasing so it lasts throughout the growing season better than the nitrate forms of nitrogen.

    We also find that ammonium sulfate is very helpful for plants that are producing any kind of oil, like soybeans that produce soybean oil. Those kind of things will take a little extra sulfates. Alfalfa crops will take a little bit of sulfates to make the sulfur-bearing amino acids. Alfalfa and legumes such as soybeans will benefit from some ammonium sulfate.

    We never use over 200 lbs. an acre. We would keep it to 100-200 lbs. as typical application rates. We find that the amount of sulfur in the air has been reduced due to the pollution and the environmental controls so that less sufur is given up by industry into the air. And while that can be helpful for the environment where there was a problem with acid rain and the pH is going very low in the soil, for farmers that means there is probably a deficiency of sulfur in the soil. And one of the best ways to provide it very quickly is with ammonium sulfate.

    A lot of recommendations that we give at International Ag Labs have ammonium sulfate. We find it to be a very important nitrogen and sulfur source that is very helpful for stimulating bacteria from the sulfates.

    The reaction against calcium is also very powerful, so a lot of times we can use ammonium sulfate to help make calcium available. It's a very important tool in the farmer's arsenal of products.

    Ammonium sulfate is not usable in organic production.

    Online Quote Request Form for Carbonized LimestoneCarbonized Limestone is a new offering from International Ag Labs. This is a new product made exclusively by Calcium Products, Inc. Carbonized Limestone is finely ground high calcium lime stone mixed with dry carbons (humates), dry carbohydrate, and liquid humate then pelletized.

    Carbonized Limestone is currently an exclusive product only available through International Ag Labs and through our Fertilizer Brokerage. We're pleased to offer this product for fall fertilization. Production is currently available.

    Carbonized Limestone is a pelletized product and it will be easy to use in a fertilizer spreader. We've seen some very good results by using this pelletized product. We've seen some very dramatic changes in the plants and in the productivity of the fields when used. We're very excited about Carbonized Limestone because we feel this is a premium product; it gets results with raising your calcium levels.

    Why “Carbonize” Lime?

    Calcium is heavy, so when it's put out in the soil, it has a tendency to sink down. Because it sinks, it'll soon go out of the root zone. Carbon, on the other hand, has a tendency to float in the soil and move up. So when we “carbonize” the limestone we end up putting both of these in each other's way, so the limestone has a hard time going down and the carbon is slowed in its tendency to go up. In effect then, the bacteria have more time to digest and break down that limestone, increasing its availability to plants.

    The “carbonization” of the lime adds to the quality, and increase the availability of calcium. The limestone in Carbonized Limestone is very high quality, nearly pure, 38% calcium, it's very finely ground, to a size of about 100-200 mesh or finer. It's actually the dust that's sucked out of the air and then pelletized. So it's one of the best limestone products out there.

    Why Not Just Use a Pelletized Limestone?

    We also sell pelletized limestone without the “carbonization”. It is a little bit cheaper, but the effectiveness is reduced in that it's not held up in the top 6 inches of the soil. It is a very high quality calcium and a very fine grind as well. The difference is just that it's not “carbonized” and that changes its efficiency.

    We find that calcium is short on most soils. We find that a lot of the restoration of soil requires addressing calcium. It's one of the first things we look at and it's one of the things that may require the most of in terms of pounds of availability. It takes a number of years to restore the calcium levels from a very depleted soil. Many times organic production fails to address the need for limestone or the need for available calcium and they have a very low level of calcium with high levels of phosphorus and potassium. This creates for a very bad situation.

    Limestone is one of the key things we use to raise available calcium. We would also consider using things like soft rock phosphate (which is a calcium phosphate), gypsum (a calcium sulfate), and calcium nitrate (which is explained by its name). All of those combined can more quickly raise available calcium. We've seen a lot of that happen in gardens when we used multiple forms of calcium. Applying multiple forms of calcium together works really well.

    Suggested Rates of Carbonized Limestone

    Typical recommended application rates for Carbonized Limestone can be anywhere from about 200 lbs. up to a ton, not very often at a ton rate, most of the time 1,000 lbs. is our upper level of recommendations. Sometimes 200-300 lbs. is going to do a lot of good, especially when you're in the middle of a growing season.

    Carbonized Limestone is available in 40# bags, 1 ton tote bags, and bulk semi-loads in hopper bottoms. It is our top suggestion to replace limestone in recommendations to Carbonized Limestone. We feel its agronomic value is probably double that of the regular pelletized limestone. That's just our rough off-the-cuff opinion.

    Chilean Nitrate 16-0-0 - Contact Fertilizer Brokerage for a Quote Today

    Chilean Nitrate 16-0-0

    Online Quote Request Form for Chilean NitrateChilean Nitrate is an organic-approved substance. It's restricted to 20% of the total nitrogen use, but it still can be used in organics. The unique thing about Chilean nitrate is that it is the only organic nitrate source available. And so if there's a need for nitrates which promote growth, this is a great product to put in it.

    It works for corn say, and would be used in conjunction with 5-1-1 fish. 5-1-1 fish would give a long term release of nitrogen, but the Chilean nitrate would be quick early growth just to get it started really fast.

    This also works really good on various kinds of greens, say if you're growing leafy greens. The only thing is you have to make sure that there's not an excessive amount of sodium already in the soil, because this does have a higher sodium content, somewhere around 19% or 20% sodium.

    This product works particularly well for crops that have a higher sodium requirement, things like asparagus and celery really need a lot of organic sodium. So this would be a great product to use for those crops even if they're not organic. It's quite water soluble and there's a little bit of boron added and some other trace minerals in with this product. So it does provide a little bit of boron.

    Overall an excellent product due to the fact that the nitrates are in there. This product is an oxidizer, meaning it will supply oxygen.

    The rating on it is a hazardous rating for shipping just because of the oxidizer effect. But it is an OMRI listed product only up to 20% of the total nitrogen requirement.

    Sodium nitrate is the standard from which all the salt index is computed. Sodium nitrate is at 100 on the salt index, it's a fairly salty material in comparison to a lot of other fertilizers, even other fertilizers aren't as high. Some fertilizers are even higher than this on the salt index, but this is the 100 mark.

    Sodium nitrate when it's mixed in with other liquids is basically a neutral on a pH, it really doesn't push the solution one way or another. It works really good to dissolve some with liquid fish and then spray that out on the soil. It's an ideal corn program.

    Sodium nitrate can be purchased in bulk tote bags. It can also be purchased in 50-lb. bags stacked up on a pallet. The tote bags are actually metric ton tote bags. So it would be 2,204 lbs. of net product on a pallet. You can fit 20 metric ton bags in a dry van and maybe we can fit 21 on a flat bed. The pallets are stacked up and they can take an equivalent amount of weight on them as well. It doesn't come in bulk hopper bottom.

    At this point Chilean nitrate 16-0-0 is kind of a pricey product. It's quite expensive this year. It's derived from a company in Chile called SQM and they're the only supplier of this product in the world.

    An interesting tidbit of history is that years ago this product was going into Germany and from that they were making dynamite and bombs. America put a blockade on that back then. Needless to say German scientists figured out how to make dynamite another way. Just history FYI.

    Chilean nitrate comes from the caliche deposits in the Atacama region of northern Chile where there has been almost no rainfall to leech the nutrients. How they originally got there is still subject to debate by geologists. For more information on this read:

  • Dextrose

    Dextrose -- Request a Quote Today from Fertilizer Brokerage


    Request quote online for dextrose from Fertilizer BrokerageDextrose is a sugar derived from corn and a lot of the corn is genetically modified so because of that, dextrose is not suitable for organic production. But it supplies carbons of soluble carbon and it's very valuable when mixed in with foliar sprays to spray on crops. It's also very valuable when mixed in with liquid nitrogen. Dextrose has a very valuable role to play in supplying the sugars that feed the bacteria as the bacteria are just beginning to break dormancy and get active in the soil.

    Dextrose is very soluble in water, it dissolves very quickly and easily, better than sucrose which is table sugar. It works very well.

    Typical rates when we're spraying it on the soil would be 5-10 lbs per acre. If foliar spraying we use about 3 lbs. per acre.

    Dextrose comes in 50 lb. bags and we stack them up on a pallet. A pallet is 56 bags, but we can make it less if we need to. We can supply it by the pallet or by the semi load of pallets.

  • Dry Calcium Nitrate

    Dry Calcium Nitrate -- Request a Quote Today from Fertilizer Brokerage

    Dry Calcium Nitrate

    Online Quote Request for Dry Calcium NitrateDry Calcium Nitrate has an analysis of 15.5-0-0 19% Ca and it's derived from reacting a derivative from the atmosphere. They pull out nitrate acid from the air and they react nitrate acid with the limestone and that is what gives calcium nitrate. So it's basically derived from limestone and the atmospheric nitrogen.

    Most of the production of calcium nitrate that's dry is done in Norway, they're the largest producer of calcium nitrate. They have a lot of hydroelectric power from waterfalls, etc. and cheaper electricity and they have limestone deposits and that's where calcium nitrate is derived from.

    Calcium nitrate is considered as a commercial fertilizer and as a result it is not approved for organics. As far as its application, it's a double growth energy fertilizer which means the calcium causes growth in plants and so do the nitrates. This is in contrast to something that would be promoting reproductive energy for say flowers and fruit.

    It's a very useful product. It's applied very well in turf, it's used quite a bit for forages and pastures. In pasture situations a lot of times we'll have 200 lbs. applied per acre in the spring, 200 lbs. in mid-summer and that will cause the grass to grow very well.

    Calcium nitrate has some very nice properties. It pulls moisture out of the air and into the soil, so it's excellent for increasing the moisture content in soils just from that effect. The dry comes in two versions. One is a coated and one is a technical grade or greenhouse grade crystals.

    The problem with calcium nitrate is that it pulls moisture, therefore if it's not coated, it'll pull moisture into the product and get it moist and soupy. So in order to prevent that, they coat the granules of calcium nitrate with a tallow or a wax, it's like a fat that prevents the moisture from coming through the product. Now once you put it out and apply it out on the soil, it begins to break down and it works fine. But this just helps to prevent that, so when you're ordering you have to know whether you want to liquify or not. The cheapest of the two is to get the coated calcium nitrate.

    The technical grade, or the crystals, is usually provided only in 50 lb. bags. These could be stacked up on a pallet. But this would be if you want to liquify it, put it down a drip line as a calcium nitrate or use it to liquify and make a foliar spray or whatnot. But you can make a liquid calcium nitrate with the technical grade.

    Calcium nitrate's very useful in crops like lettuce, spinach, cabbage, cauliflower, broccoli, celery, things of that nature give great response to calcium nitrate.

    Calcium nitrate comes in tote bags that are 2,000 lbs. each bag with granules that are coated. It would also come in 50 lb. bags that are coated stacked up on a pallet. It might be more than a ton on a pallet. The crystal grade comes by the 50 lb. bag or by the 50 lb. bags stacked on a pallet and it's possible it could be even in tote bags, but then it would have to be kept very well sealed and used up all at once when you use it. So it's not recommended in that form.

  • Humates

    Contact Fertilizer Brokerage for a Delivered Quote for Humates


    Online Quote Request FormHumates are a very soft coal called leonardite. They're primarily carbon with a lot of trace minerals and they're normally ground quite fine. They provide a lot of good carbons derived from ancient trees or jungle, etc.

    Humates come in 2 forms, the dry form and the liquified form. What they do is grind the leanardite to make a dry humate. They can also take those dry ground humates and put that in with various alkalizing substances to make a liquid. The liquid is actually made soluble so it's not just in suspension, but it's soluble liquid humate. We work a lot with soluble liquid humates and when they're made right, they can help supply carbons in the soil. They also stimulate biology and do a lot of good things.

    Humates have carbon which causes the soil to have a tendency to rise, humates always want to come up in the soil, always seeking to come to the surface, just like a cork in the water that always wants to float. So what we use dry humates for especially is to carbonize limestone, because  when we put calcium out in the form of limestone, it wants to sink into the soil and as it sinks it goes out of the root zone.

    The thing that we've done is use dry humates to mix in with powdered limestone. We use 15 lbs. per ton of dry quarry limestone and we mix that in. It mixes in very easily, it just kind of electromagnetically mixes right in. It turns the white limestone a gray color and we basically have a really nice product because the limestone wants to go down and the carbons up. They get in each other's way, and that allows more time for the biology to break down the limestone and release the calcium out of it. It works out really good. The carbonized limestone works really well to make the calcium more available by giving the microbes more time to digest the limestone.

    For most all other applications we're recommending the use of small quantities of liquified humates because they're already soluble and ready to go to work. The dry humates as far as the stimulating effect on biology, it's just not very quick.

    We offer humates in 50 lb. bags on pallets and it's very fine stuff that can be mixed with limestone. If you're interested in liquids, you can contact our office for pricing and availability of products.

  • Liquid Ammonium Phosphate 10-34-0

    Liquid Ammonium Phosphate 10-34-0 -- Request a quote from Fertilizer Brokerage today!

    Liquid Ammonium Phosphate 10-34-0

    Online Quote Request Form for Liquid Ammonium Phosphate 10-34-010-34-0 is a liquid ammoniated phosphate. It has 10 units of nitrogen and 34 units of phosphate and of course 0 units of potassium. It's very frequently used in a starter where it can be mixed with other components such as microbial innoculants, and some liquified sugar or molasses. It could even include some additional nitrogen.

    It's usually put near the seed or a little off to the side, we typically recommend 2 1/2 inches over and 2 1/2 inches down from the seed. That's known as 2 X 2.

    10-34-0 is phosphate that is in a polyphosphate form as opposed to orthophosphate. And what that means is that certain phosphate molecules are joined to each other. They're joined together, therefore as is, the plant doesn't immediately take it up but there has to be a chemical reaction caused by biology to separate the phosphate from itself to make it an ortho so it's all by itself.

    So take precaution with 10-34-0 because it's 100% polyphosphate and it takes microbial activity to break it apart. It's a good idea to put in a biological innoculant and a starter. It's also very good to put in a liquid sugar and then some things that stimulate the bacteria. So some things that could go in there would be a product called RL37, it's a liquid humate, and also a little bit of liquid B12, a very small dose, let's say 30 ml per acre is a good rate to use. It's just a good stimulant for bacteria.

    One other ingredient that goes very well with 10-34-0 that a lot of farmers don't choose to use (but if they do they can get some very good results) is to put in some liquid fish in addition to the 10-34-0. It's a very good addition and it pays really well. You just have to have the equipment to handle it and the patience to mess with it.

    10-34-0 is also used as a base product to make some 9-18-9, so 9-18-9 can have some 10-34-0 in it. And if it's got some in it, it won't be a clear liquid because the 10-34-0 is colored. So a lot of times the 10-34-0 provides some polyphosphates in a polyphosphate-orthophosphate mix in the 9-18-9.

    There are different grades of 10-34-0. A good grade is clear, but most of the time you get a green-colored 10-34-0 and ocassionally a black 10-34-0 which isn't a good quality. You don't want the black. Green is acceptable, but clear is of the best quality.

    10-34-0 is available in bulk semi load. We can supply approximately 4,000 gals. per semi. It would need some tank storage to be delivered to farmers.

  • Liquid Calcium Nitrate

    Liquid Calcium Nitrate - Request a Quote from Fertilizer Brokerage Today!

    Liquid Calcium Nitrate

    Online Quote Request form for Liquid Calcium NitrateLiquid calcium nitrate is the technical grade of calcium nitrate that's been liquified. The commercial grade of liquid calcium nitrate has an analysis of 9-0-0 11% Ca. So it's a very saturated product, it's quite heavy, about 12.2 lbs. per gallon. It's used and liquified with steam, we don't do it ourselves, we just buy it already pre-liquified.

    It's a very good product to mix in with foliar sprays. Its best application is actually in foliar programs. We like to mix in with Amaze, for example, if you want to have growth energy on crops such as lettuce, etc.

    There is no sugar in the 9-0-0 11% Ca. So whenever you use liquid calcium nitrate, it's recommended to add sugar.

    A very nice use of liquid calcium nitrate is in a fall residue program, and this would be where you have maybe 5 to 10 gallons of liquid nitrogen, such as the 28% or the 32%. We'd add in some sugar, say 5 lbs. of dextrose. Then we'd put in some RL37 and for the bacteria we'd use Z-Hume at the rate of about 2 qts. per acre. But to round out the nitrogen to the 28% or the 32 %, 1 or 2 gallons of calcium nitrate could be applied, and even a little ammonium thiosulfate, 1 or 2 gallons.

    So if you had about 10 gallons of nitrogen, 1-2 gallons of calcium nitrate, 1-2 galloons of ammonium thiosulfate, you can have a very nice mixture. You can put the sugars in there and the Z-Hume and it's wonderful to promote the breakdown of residue. And the calcium nitrate and the ammonium thiosulfate mixed with the nitrogen create all the components of an amino acid. So it's very easy for the plants and the bacteria to grab this and use it. And because it's in an amino acid form, it won't leach away, so it helps to stabilize that nitrogen. This is a superior way of stabilizing nitrogen that actually stimulates bacteria as compared to some of the commercial nitrogens that have slow release and what they're doing is inhibiting the bacteria. That's a very bad way to inhibit nitrogen. This is a much superior way of doing it.

    Liquid calcium nitrate even in small quantities put into starters in the springtime is very valuable, putting a little bit in with some nitrogen, not with the phosphate. This should never be mixed in with the 10-34-0, because liquid calcium nitrate and 10-34-0 are going to make a big mess and they won't go through the system and they'll bond together and make cottage cheese texture of the product. So you want to add it to nitrogen or potassium but not adding calcium nitrate to any other liquid phosphates.

    If you want a calcium nitrate and phosphate mixture for a foliar spray, we've done that with our Amaze product. But that's a very specialized product. Otherwise, for commercial applications you always want to keep these two apart.

    Some people have put liquid nitrogen mixture on one side of the seed and putting the calcium nitrate in with that, and then putting the starter with the 10-34-0 on the other side of the seed, or maybe a 4-10-10 or whatever. As long as it's not burning the seed and if there's not too much, that combination really gets a lot of energy right to the seed and can be very helpful for good, quick early growth in seedlings. Calcium nitrate is available in bulk semiload tankers at about 4,000 gallons in a tank. You would need to have tank storage before ordering this.

    If you're looking for totes or smaller quantities, we'd get it from our warehouse so you need to contact our office to place that order. But for bulk loads call Gary for pricing on that.

    We do pull this product from mutiple locations in the US, so we don't warehouse this in any large quantity in Minnesota. We do, however, have a full distribution network of warehouses around the country to draw from. So even if you're living quite a distance from us, still give us a call to see if we can get you a competitive price. We just might surprise you!

    2-5-0.2 Liquid Fish -- Contact Fertilizer Brokerage to request a quote today!

    Liquid Fish 2-5-0.2

    Request a quote onLiquid-Fish-2-5-0.2Liquid Fish 2-5-0.2 is fresh water fish. It's made by grinding the fish scraps, including the head, the guts, and everything else in there. They then acidify it with some phosphoric acid. The enzymes from the fish guts are what digest and break down this fish. They let it sit for a couple of months while it's digesting and breaking down. So the real nice thing about this fish is that it yields a good level of calcium and phosphorus and a lot of colloidal trace minerals coming right out of the bone. It's an excellent fish for the calcium and the phosphorus. There's about a 1% calcium content and about half the phosphorus in the analysis (a total of 5) is derived from the breakdown of bones, the other half is from the addition of the phosphoric acid.

    We find this to be a very good fish to be used for soils that are short on soluble or available phosphates. This can be a very quick and immediate boost. It really can push the energy of the soil up. This fish could also be used as a foliar spray because of the phosphoric acid. And in foliar spraying we would probably put about 2 quarts up to a gallon per acre.

    Typical rates for very low phosphorus organic soils would be somewhere around 30-50 gallons an acre. That'll give a very nicel level of available phosphorus for the growing season. It will also supply acidity because this product has a pH of about 3.5. It provides acidity to breakdown and acidify the limestone and soft rock phosphate that could very well be included with this fish as part of the program. This is a soluble portion that helps to make the soft rock phosphate more available. So they work together.

    We use this fish primarily in organics on low phosphate soil. And we would use a 5-1-1 fish more frequently in organics on a nitrogen-loving crop like corn. And a lot of times we'll use the 2-5-0.2 liquid fish on the organic soils in things like beans or pasture production where you need to get your phosphates up. That's primarily where we're using this fish.

    It comes in bulk semi loads, about 5,000 gallons (or a little over) per bulk tanker. Or it could be purchased in smaller quantities in totes or semi loads of totes. The best pricing is definitely going to come by full semi loads, whether in totes or in tanker.

    Liquid Fish 5-1-1 -- Request a quote from Fertilizer Brokerage today!

    Liquid Fish 5-1-1

    Request Quote Liquid Fish 5-1-1 Liquid Fish 5-1-1 is excellent ocean fish that's high in nitrogen and full of trace minerals. The fish is first used for oil, so the oil is taken out of the fish but the rest of the meat and the body of the fish is then ground up and made into an emulsion. So there's a lot more protein in this fish coming from the meat than most other liquid fish that are scraps with the filet taken out.

    This is not an edible fish really, it's harvested mainly for the oil. The oil is used for human consumption and various other aspects because it's high in omega-3 oil. But what's left over is a very good fertilizer for organic production or for small-scale market gardens. The primary use we're looking at is as a high nitrogen source for organics.

    This is especially important when raising corn where we need a good nitrogen source. The nice part about this fish is the nitrogen is in the source of amino acids or proteins that are very stable. So the nitrogen in this product, unlike commercial nitrogen in fertilizers, will stick around and supply the plant throughout the whole season.

    Typical rates would be anywhere from 30 to 50 gallons (sometimes 60 gallons) per acre, depending on yield goals for corn. Small grains would take less. Wheat would be close to the corn range. Many times this would work as a complete stand alone product for corn. If you just put 60 gallons out you'll probably get a corn crop. Not ideal, but it can be very useful of a product.

    The sulfates in this liquid fish 5-1-1 help to acidify high pH soils. A lot of times soils are pushing up that 7-8 pH. Sulfates help to release that and work against the calcium, dropping the pH a little, so it's good for energy release working against the calcium.

    Liquid Fish 5-1-1 is delivered in semiload tanker lots and would need about 5,000 gallons of tank storage if we were to quote it delivered.

  • MAP 11-52-0

    MAP 11-52-0 -- Request a quote from Fertilizer Brokerage today!

    MAP 11-52-0

    Online Quote Request Form for MAP-11-52-0MAP 11-52-0 is also called Monoammonium Phosphate. It has an analysis of 11 units of nitrogen, 52 units of phosphate and of course 0 units of potash. It's a lower PH phosphate fertilizer, it's an excellent dry, it has a PH similar in about the 5's.

    There're 2 versions of ammoniated phosphates for the most part. One is MAP and one is DAP. The common one is DAP--Diammonium Phosphate, which has an analysis of 18-46-0. A lot of fertilizer plants like DAP because it has quite a bit of nitrogen, so when they're blending these specific blends, maybe like a 15-15-15 or whatever, they've got an analysis that's pretty high already in nitrogen.

    But we find that DAP is decidedly inferior to MAP, first of all because it has a high PH, and it bonds with phosphate more readily than it bonds with the calcium that's in the soil, forming an insoluble tricalcium phosphate. And when that happens, then you lose the solubility of both your phophorus and your calcium. So you end up being shorter.

    The Monoammonium has much less of a problem of the phosphates tying up with the calcium. It's kind of like the Monoammonium Phosphate is a better referee, keeping the phosphates from tying up with the calcium in the soil. So whenever we recommend 11-52-0, we do not suggest substituting Diammonium with that, it's not as good.

    The other problem that you have is that Diammonium Phosphate has a PH of 8 or even a little higher, so when you have soils moving up a little bit higher in PH (and a lot of soils are moving up higher in PH), you get less of a reaction of energy with a high PH fertilizer mixed with a high PH soil. You get much better release of energy by mixing a low PH fertilizer with a high PH soil. And that's what the MAP does.

    We find that 100 lbs. of MAP applied per acre in a broadcast situation will supply the needed phosphates for 1 cropping season. And it probably will build your available phosphates a few pounds as well.

    This is used as an adjunct to a soft rock phosphate, so if you really want to rebuild and remineralize soil, you use both of these. The MAP for the crop you're growing now, and the soft rock phosphate would be used for long term soil building so that eventually you don't have to buy the MAP or the commercial fertilizer. But if your soil indicates a low level of available phosphates, it is very prudent to supply phosphates in the soluble form in order to get a good crop so you can pay for the building of the soil in the form of soft rock. So we use them in combination. If budget is an issue, then we take the soft rock out because that is very expensive on large-scale acreage, and we just use the MAP.

    You can go along year after year and whenever you're low use MAP and you'll be just fine. 100 lbs. and even up to 200 lbs. of MAP is a very small amount when you spread it out over a whole acre. It's basically like salting your food, you really don't want much, but it's amazing how just a little amount of salt makes your food taste better, it gives just enough soluble salts to improve the flavor. Well, it's the same comparison putting soluble salts out with the MAP. But again, like table salt, you don't want to overdo it and you want to have about the right amount. That right amount is anywhere between 100-200 lbs.an acre, no more than that.

    We use MAP most of the time when the soil tests show less than 150 lbs. of phosphate, we'll put either 50 or 100 lbs. out.

    MAP is the only commercial phosphate that we recommend for dry application. Also, the phosphate is in the "ortho" form. Polyphosphate is orthophosphate which means the phosphate molecules aren't connected to each other, they're all separated one from another in their molecular structure, so that when you put it out the plants can immediately pick it up and use it.

    A very good product. Some people have been very concerned that there's some problems with MAP. We haven't found or seen any problems with the use of it when it's needed.

    If you're putting fertilizers down a slot, which is not our recommendation, but if you're doing that you would typically cut your rates in half. So you would go 50 lbs. or 75 lbs., not much more than that, and that would have to be place beneath the seed about 4-5 inches so you don't burn.

    The best use for building up a soil is to broadcast your fertilizers and slightly work them in, that way when the plant roots go out to search for nutrients in between rows there're nutrients there. And so strip tillage and where you place them, you're just banding nutrients either beneath the plant or beside it only, it basically depletes the area in between the row as it becomes a poverty zone for soil. So our suggestion is to broadcast MAP along with all the commercial fertilizers. Then the possibility exists to come in aand do a side dress or something like that beside the seed row, just as a stimulant to the plants as they're getting off. And you could put some bacteria and humates with it.

    MAP is available by hopper bottoms, available in 25-26 ton semi load units. If you need a semi load and you want to check prices to compare them against your local coop, give Fertilizer Brokerage a call and we'll get you that information.

    Pelleted Chicken Manure

    Contact Fertilizer Brokerage for a quote on Pelleted Chicken ManureInternational Ag Labs has found a good source of chicken manure that comes from cage layers. It's dried and pelletized and put into a granule. The analysis is 4-3-2 11% Ca -- this is a pretty significant calcium source.

    Chicken manure provides a good form of natural boron and a lot of trace minerals as well. Due to the high heat and the processing of this, there would be no biology in it, but the minerals and the organic materials would make for a very good enhancement in soil.

    This product is very good to be used along with the other minerals needed to remineralize the soil, particularly soft rock phosphate and limestone. The reason this assists in that is that the chicken manure will begin to break down in the soil fairly quickly. As it does, it creates organic acids and those organic acids help break down the mineral fertilizers that are nearby. So the acids would help to break down the soft rock phosphate and the limestone, making both the calcium and the phosphorus more quickly available to the crop.

    The chicken manure provides some good organic material as well and this would actually release some carbon dioxide into the soil which can be picked up by the root and can be an in-soil source of carbon dioxide, which is many times lacking in many fertility programs.

    This product is available by bulk semiload at present, and in the future it may be available in tote bags.

    If you have any further questions, you can call Gary for pricing at the number above, or if you want to know more about the impact of chicken manure, you can send your request to International Ag Labs via the form below.

    Pelleted Gypsum -- Request a quote from Fertilizer Brokerage today!

    Pelleted Gypsum

    Online Quote Request Form for Pelleted Pelletized GypsumPelleted Gypsum is a very remarkable product. It's calcium sulfate and is used in a number of different applications. It has sulfur in the sulfate form, so it's all ready to be used by plants. The analysis shows it has 17% sulfur and 22% calcium.

    It is a little bit slower reacting for a sulfate than say ammonium sulfate or potassium sulfate, but the gypsum works to take out excessive sodium. It will work to put the right ratio into place between the calcium, the magnesium, the potassium and the sodium. So it just kind of helps to put all of those cations in proper ratio with each other.

    We use it to leach excessive sodium. It provides sulfates in organic production for something like soybeans where we need to get some sulfates out there. We use it when the soil is going anaerobic and this will help pull it back up to a more oxygenated environment in the soil.

    Pelleted Gypsum works very well in combination with limestone and soft rock phosphate and together they have some kind of a strong synergistic effect between the three of them. And really gypsum is kind of an unsung hero in modern production. It is critically important and we use it in a lot of applications. Most of the soil programs we make use gypsum. It's also very useful to supply calcium to something like blueberries where you want to keep the pH a little bit lower, so it's helpful there.

    So those are some the benefits of pelleted gypsum. We frequently will use from 300 to 500 lbs. per acre. And for the most part, 500 lbs. is a maximum application rate. The only time we go against that rule is out in western soils where we have really extremely saline soil or sodic soil that has got some problems that need to be leached. And so then we might go up to a ton per acre rate.

    Pelleted Gypsum is available in bulk hopper bottom, ton tote bags and it's also available packaged up in small bags that are put on 2,000 lbs. per pallet, but in small bags that can be broken down. It's a very clean pellet, not a dusty or broken pellet. It's a very nice product and it would mix very well in a fertilizer spreader and spread out. It doesn't react very much with other fertilizers. Overall Pelleted Gypsum is a very important part of growing quality crops.

  • Potassium Sulfate 0-0-50

    Potassium Sulfate 0-0-50 -- Request a quote from Fertilizer Brokerage today!

    Potassium Sulfate 0-0-50

    Fertilizer Brokerate Online Quote Request Form for Potassium Sulfate 0-0-50Potassium Sulfate is a very important product. It's used to supply potassium. Conventional agriculture, for the most part, supplies potassium with a muriate of potash or what's called 0-0-60. We don't handle that because it has chlorides. It's potassium chloride which is very detrimental to soil biology.

    But potassium sulfate provides not only 50 units of potassium, it also has 17 units of sulfur, so when you add that up, you've actually got a lot more fertilizer for what you're paying for. It has a lot more energy than the potassium chloride and what we find is that 100 lbs. of potassium sulfate will be sufficient to provide the potassium for a whole year when the potassium's quite low.

    For those concerned about their budget in regards to the cost difference between 0-0-60 vs. 0-0-50, what we suggest is to take the same amount of budget (dollars per acre) that would normally be spent with 0-0-60 and put it into the potassium sulfate 0-0-50. You'll get less product, but you'll get a better product that provides better effect for the soil.

    Potassium can also be supplied with compost and manure, so it shouldn't be put on unless you know that you do need potassium.

    At this point potassium prices have remained pretty high globally, and potassium sulfate is no exception. For that reason, it really is important to see if you truly need it before putting it on. A soil test would be recommended.

    One of the benefits of potassium sulfate is that it's not an extremely high pH fertilizer product. Potassium chloride, on the other hand, is quite a bit higher in pH and has the tendency when used over time to push the pH high and that can be misleading for people that look at pH and then don't put any calcium or limestone down. Potassium sulfate, because of the sulfate actually, will not push the soil pH. It's more of a neutral pH, so it's quite superior just from the aspect of the pH.

    Some crops are very potassium-loving, so we would use a little higher rate than 100 lbs. per acre. Some of the things that come to mind include potatoes and pumpkins. Those really use a lot more potassium, so we would go up to 200, sometimes even 400 lbs. of potassium sulfate depending on what the soil condition is what crop is being used.

    A lot of soils, especially smaller market gardens, don't need it. But a lot of the larger scale agricultural operations find a need for potassium sulfate. They show up as being short.

    International Ag Labs is offering through the brokerage to get potassium sulfate in bulk hopper bottoms, also in tote bags. We have a potassium sulfate that is approved for organics and we have one whose binding agent is not approved, but the product is a very clean natural product from the earth. Se we can supply 0-0-50 for organic production and for those who are biological farmers it doesn't matter. If you want a cheaper price, we can supply that as well without the organics label.

  • Soft Rock Phosphate

    Soft Rock Phosphate -- Request a quote from Fertilizer Brokerage today!

    Soft Rock Phosphate

    Online Quote Request Form for Soft Rock PhosphateSoft Rock Phosphate is an important phosphate source that is actually a byproduct from the old time hard rock mining. In order to increase the purity of the higher analysis of the hard rock, the soft rock was a clay impurity which was washed and then it was sent in this water through to a settling pond. So then it filled this settling pond up and so these are huge huge settling ponds and the surface dries out and the soft rock is skimmed off the top of the settling pond and then it can either be processed or sold as is.

    Hard rock phosphate, in contrast, is mined just as it is and is a tri calcium phosphate, sometimes is has a little carbon. But it is extremely insoluble in the soil. It requires a hyperactive bacterial system and a tremendous amount of soil acidity in order to derive much benefit. Soft rock, on the other hand, is quite a bit more available. A lot of times we'll see availability showing up on the soil test within 1-2 years, even the first year if a soil's got some acidity.

    There are a tremendous amount of trace minerals in soft rock phosphate and there's a certain electromagnetic energy or field with soft rock phosphate so that it's extremely sticky. If you get it wet, you can feel how sticky it is. This electromagnetism helps to hold calcium up in the root zone. So it's a real critical part of building the soil so that you can hold the calcium.

    Soft rock is also a pretty good supplier of silicon, it has a decent amount of boron in it, and then a whole bunch of other trace minerals, about 60 trace minerals all together. And we find it to be an absolute critical ingredient in building soil phosphorus levels for organics. And any time the goal is quality, soft rock phosphate should be part of what is used to build and maintain soil phosphate levels.

    We supply this from two sources. One source is from Idaho, and this is not a processed product so it's pretty much just skimmed off the settling pond and put into bulk hopper bottoms or tote bags. And we sell it by the semi load, so either a 25-ton semi load in bulk (or 22 tons), and if we can get a flatbed, 24 tons in tote bags. The tote bags are not standardized in their weights, but overall the semi load will be 22-24 tons.

    We also sell a Florida soft rock phosphate. This has been granulated so that it makes it a little easier to work with. The granulated form can be used in a fertilizer spreader, but it is dusty, it's not a perfect pellet and it will coat the beater blades on the back of a spreader, so even though it is granulated you still eventually have to go back and clean those blades as you're spreading soft rock phosphate. Otherwise it just builds up and coats the blades.

    The advantage of the granular, of course, is that it can be spread with a fertilizer spreader. The Idaho source needs to be spread with a lime spreader and even in that situation sometimes the soft rock will still bridge in the spreader and someone's going to have to knock down those bridges so you can get it to spread. It is a little cumbersome product. Another way it could be done is the powdered product that could be added to a liquid manure and then mixed in with the manure and then spread out as liquid as part of the manure, which is very good way to do that.

    Soft rock phosphate, again, will hold the calcium, and that's really key if you want to build available calcium and also to build a soil that is capable of producing nutrient dense foods. So it's kind of a foundation point.

    Soft rock phosphate is not recommended automatically, you need a soil test to determine if you need phosphates. Many soils, especially those with composted manure have excessive phosphates. And consequently soft rock phosphate is not recommended on those soils. So make sure that the soil is tested beforehand.

    The Idaho soft rock has 8% carbon content, that gives it a nice chocolate brown color. The Florida source has less carbon but has a little higher analysis of phosphorus and calcium. So they're both good products, we like them equally. They both fit into a good biological program to grow quality.

    Specialty Fertilizers

    Online Quote Request Form for Specialty FertilizersPotassium Nitrate 13-0-46

    Potassium nitrate is a water soluble dry fertilizer. It comes either in prills or the granular form like large crystals of sugar. It's analysis is 13-0-46, thirteen units of nitrogen and 46 units of potassium. It is mostly sold using the water soluble form, and that can be made into liquid fertilizers.

    Potassium nitrate can be used on crops where you need growth energy and you need the potassium and nitrogen. It could go well on leafy greens that are short on potassium, it could go very well on celery. One place it's used is on tobacco. Some people use it on turf, although we suggest not to have very high levels of potassium on turf and grasses.

    It's available by the 50 lb. bag on a pallet and it could possibly be available in a tote bag. But the most common way it's sold is by the 50 lb. bag stacked on a pallet and sometimes those pallets are over 2,000 lbs, maybe even up to 2,400 lbs.

    Potassium is a rather expensive product and this is a premium form of it. For this product you can expect high prices, that's just the way the market is at this time.

    Water Soluble Potassium Sulfate 0-0-52

    We discussed potassium sulfate on another page, but this would be a 0-0-52, this is a water soluble potassium sulfate. It's a very nice product to use down drip lines or for people who want to formulate products of their own. It dissolves in water, and it provides potassium and sulfur in a sulfate form.

    Monoammonium Phosphate (MAP) 12-61-0

    This is a technical grade of monoammonium phosphate (MAP). The analysis on that is 12-61-0. This also looks like sugar crystals and is used to make liquids or to formulate and make dry blends that are water soluble blends.

    This would be available in 50 lb. bags stacked on pallets and we can sell any number of pallets. If you want a bag, you can buy bags of these products directly from International Ag Labs.

    Monopotassium Phosphate (MKP) 0-52-34

    Monopotassium Phosphate (MKP) is another specialty fertilizer we broker. The analysis on that is 0-52-34. This is a very high quality product. It's got both phosphorus and potassium, the phosphorus is in a phosphate form so it's ready to work for plants.

    This is used for drip lines when we need to increase the amount of soluble phosphorus and potassium. Many times in greenhouses we see a tremendous demand for potassium, and the phosphorus may not yet be built up, and so in such a situation this product can do a very good thing.

    Specialty Product Blends (dry water soluble powders)

    1. Mixed NPK Blend 20-20-20 - For when you want to increase the conductivity in the soil and you want an even mix of nitrogen, phosphorus, and potassium.

    2. 10-52-10 - This is used when we're looking for just a touch of nitrogen and potassium and a very strong portion of phosphates.

    3. 20-40-0 - Another dry mix, this time with 20 units of nitrogen, 40 units of phosphate and 0 on the potassium. This would be a product we'd use down drip lines in greenhouses primarily. When we want to a good increase in the nitrogen and a very steep increase in the amount of phosphorus. And where the soil may be extremely high in potassium, we don't want to put any potassium down there, so this is the product we'd use.

  • Starter Fertilizer 8-25-0

    Starter Fertilizer 8-25-0

    Starter Fertilizer 8-25-0Starter Fertilizers

    It was April 29th and 38° as I drove into work. By this time 20% of the corn has been planted in our county. It was cold and rainy. While the rain is welcome the cold is another story.

    Cold soil temperatures have a direct impact on the availability of phosphorus in soil. The cooler the soil, the more phosphorus is tied up. This tie-up of phosphorus directly impacts the health of emerging seedlings. Tied up phosphorus in soil means the plant will likewise be deficient in phosphorus.

    Phosphorus is the P in ATP. ATP is a critical component in the energy cycle of plants. When phosphorus is low in plant tissue plants grow slower, have reduced root mass, and are more susceptible to insect and disease pressure.

    When seeds germinate and find a plentiful supply of available phosphorus, the emerging seedling will have a higher level of phosphorus in its tissue. By the time a corn plant reaches V2, its pattern of phosphorus sufficiency or insufficiency is mostly cemented in place. The goal is to set the health of the seedling with dry matter phosphorus readings of 0.35% or higher in the plant tissue.

    Here are some guidelines for testing phosphorus: harvest the entire plant at V2 and submit for a plant tissue analysis.

    % Phosphorus on Dry Matter Basis
    0.15%      Critically Deficient
    0.25%      Low
    0.35%      Sufficient
    0.45%      Excellent Level

    Roots are the foundation of plant health. When soils are wet and cold, seedlings do not have aggressive root growth. At the same time soil phosphorus is virtually all tied up. With less root mass there is less uptake of phosphorus. To have healthy roots a seedling must have an adequate supply of phosphorus. This leads to the circular situation where seedlings need phosphorus to grow roots so they can get the phosphorus they need.

    The solution to this predicament is to use a starter. The colder and wetter the soil, the more critical a starter becomes. Of course not all starters are equal so let’s explore some options.

    Chemically, phosphorus is available in 2 forms: ortho and poly. Plants utilize phosphorus only in the ortho form, H2PO4. When 2 or more orthophosphate ions join together it becomes poly phosphate. Polyphosphate cannot be used by plants. First the phosphate ions must be detached by microbial digestion to become orthophosphate.

    The problem with using polyphosphates as a starter is that cold, wet soils do not have enough microbial activity to convert the poly to ortho quick enough. To be healthy seedlings need to get out of the ground and to the V2 stage with at least 0.35% phosphorous.

    This is why a starter needs to be 100% orthophosphate. Late planted corn that germinates in warm soil could probably get by with a 70:30 ortho/poly mix.

    One word of caution when selecting a starter; just because a fertilizer is ortho does not mean it is your best choice. DAP or diammonium phosphate is 100% ortho phosphate. It is available as a fertilizer grade, 18-46-0, or the technical grade 21-53-0 that can be liquefied. This fertilizer will give off free ammonia that will harm the seed and burn seedling tissue. Urea can do the same thing. Do not put either of these with the seed.

    International Ag Labs has a 100% orthophosphate starter with an analysis of 8-25-0. It also has 0.1% zinc and 0.1% manganese. We purposely do not have potassium in the starter to keep the salt index as low as possible.

    This starter is available by the semi load or by 275 gallon totes from our warehouse. We also have live microbial inoculants and support packages that can be applied with the starter. Give us a call if you would like to talk. 507-235-6909.

  • UAN 28% / 32%

    UAN 28% / 32% -- Request a quote from Fertilizer Brokerage today!

    UAN 28% / UAN 32%

    Online Quote Request Form for UAN 28% / UAN 32%UAN 28% and 32% are both formulations of the same thing, urea-ammonium nitrate, with a 28% nitrogen on one and a 32 % nitrogen on the other. The reason they have both forms is that 32% is how it's produced as a full concentrate and it's used more in southern climates. Then as it gets more in northern climates, especially if it's going to face a winter season, then they dilute it with water because the freezing point is less for the 28%. So the 32% more easily freezes and then it may drop off and salt up.

    28% is a very good nitrogen and a pretty clean nitrogen, something we recommend because it's basically a nitrogen that's coming out of the air. It's a better source of nitrogen than anhydrous ammonia which is very hard on soil structure, it's very hard on all sorts of biology. But the 28% is a very good nitrogen. It's very important for corn production and we normally would always mix in 5-10 lbs of sugar when we're using that because you want to add in soluble carbons to slow-release the 28%.

    One very nice formula that really goes good to make the nitrogen soil release is if you're using 10 gals. of 28% or 32%, you would add in your 5-10 lbs of dissolved sugar, then you could add in 1-2 gals of Thiosol and 1-2 gals. of ammonium sulfate and you could probably throw in a quart or two of liquid humates (RL37). That has all the components of an amino acid--nitrogen, carbon, hydrogen, oxygen, calcium, sulfates--and it really works good to hold the nitrogen throughout the season that way instead of losing it so quickly.

    28% (or 32%) by itself is going to fairly quickly be lost to the atmosphere or leeched, so the nitrogen doesn't stay around so long. But when you put in the sugars and add some of the other components it will stay around much better and work for the plant.

    Ammonium sulfate is a good product to use as a broadcast in conjunction with 28% or 32%. About 200 lbs of ammonium sulfate is pretty good and then take the rest of the nitrogen needs using 28% or 32%.

    We can offer this in brokerage in approximately 4,000 gallon semi loads. It's available basically in bulk, we don't have much opportunity to sell it in totes at this point. But it is available for those who need larger quantities. Pricing varies frequently, so you have to request a quote. It is a good product and a pretty clean product for commercial fertilizers.

    This would not be approved for organics, of course, because it's a commercial nitrogen.

  • Urea 46-0-0

    Urea 46-0-0 -- Request a quote from Fertilizer Brokerage today!

    Urea 46-0-0

    Online Request Form for Urea 46-0-0Urea is 46% nitrogen, so its analysis is 46-0-0. This actually has carbon in it, so in a sense, you could call it an organic nitrogen. Not that it's approved for organic use, but it does have carbons in with the nitrogen so carbon is part of the molecule of urea.

    Urea is a high analysis dry nitrogen. It has a tendency to dehydrate the soil, so it has to be used where there is adequate water. In the right place it can be very useful.

    One of the uses it's really good for is in corn when the equipment requires a dry application of nitrogen.

    Urea is a dry granular, so it can spread with a fertilizer spreader just fine. It mixes pretty well with phosphorus and potassium products. You do have to be careful mixing it into limestone. Pelletized limestone and urea would not stay in very well together.
