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)
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.
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.
- 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.
