Using Gypsum to Help Reduce Phosphorus Runoff USDA

Feb 21, 2017  The advantage of the gypsum is that it reduces the amount of water soluble P that can be lost through runoff or leaching without causing any permanent reduction in P available to plants. If soil test P levels are extremely low, then the addition of gypsum could potentially further reduce the P available to plants.

Phosphogypsum - an overview ScienceDirect Topics

Phosphogypsum is a waste by-product from the processing of phosphate rock in plants producing phosphoric acid and phosphate fertilizers, such as superphosphate. The wet chemical phosphoric acid treatment process, or ‘wet process’, in which phosphate ore is digested with sulfuric acid, is widely used to produce phosphoric acid and calcium sulfate, mainly in dihydrate form (CaSO 4 2H 2 O):

Di-calcium phosphate by direct acidulation of phosphate rock

theoretically, however only mono-calcium phosphate and undecomposed phos­ phate rock result in practice. Both mono-calcium phosphate and di-calcium phosphate are effective plant foods, however di-calcium phosphate not only requires less sulfuric acid in manufacture but is also neutral and has good physical properties.

Gypsum vs agricultural gypsum - Houzz

Apr 18, 2014  Calcium superphosphate is actually a combination of monocalcium phosphate and calcium sulfate (gypsum), so it's the next-best thing you can use if you can't find pure gypsum. It should not affect the pH much. I also wouldn't worry about the extra phosphorus - most excess P ends up being locked up anyway.

Understanding phosphorus fertilizers UMN Extension

Both the wet and dry treatment processes produce orthophosphoric acid, the phosphate form that’s taken up by plants. The phosphoric acid produced by either the wet or dry process is frequently heated, driving off water and producing a superphosphoric acid. The phosphate concentration in superphosphoric acid usually varies from 72 to 76 percent.
