Hard Rock Phosphate
We have about 7,000 US tons of hard rock phosphate available for anyone that may be interested. It has a moisture content of around 13.5% and when it is dried it has a phosphate content around 30% with a similar amount of calcium.
This would be useful to grind and mix into methane digesters or to mix into compost operations. You can also make single super phosphate if you have a supply of sulfuric acid.
Direct field application should only be done on very acidic soil.
Your cost is $45/ton FOB Port Sutton in Tampa, FL. Below you can view some pictures along with the analysis FYI.
Let us know if you would like a delivered price in bulk only, specify if you can receive a bulk hopper bottom or if you need a bulk end dump. Truck-load quantities only. First come first served.
