Chemical Fertilizer P in Soil. The modern terrestrial P cycle is dominated by agriculture and human activities (Oelkers and Valsami-Jones, 2008).The concentration of available soil Pi seldom exceeds 10 μ m (Bieleski, 1973), which is much lower than that in plant tissues where the concentration is approximately 5 to 20 m m Pi (Raghothama, 1999).Because of the low concentration and poor

Gypsum is a slow-release source of sulphur and calcium which play a key role in improving soil structure, aeration and water retention. So you can grow better, healthier crops.When Gypsum dissolves, it releases equal proportions of calcium and sulphate. Calcium sulphate improves the structure and consistency in soil and most other growing media allowing better water penetration and retention

Gypsum: an old product with a new use. Gypsum is calcium sulfate (CaSO 4 ). Refined gypsum in the anhydrite form (no water) is 29.4 percent calcium (Ca) and 23.5 percent sulfur (S). Usually, gypsum has water associated in the molecular structure (CaSO 4 ·2H2O) and is approximately 23.3 percent Ca and 18.5 percent S (plaster of paris).

Gypsum contains sulphur as sulphate, the form taken up by plant roots. The sulphur in gypsum is readily available, so gypsum can be used where a quick response to sulphur is required. Gypsum has little if any effect on soil pH. It cannot be used as a substitute for lime to correct soil acidity, i.e. to raise the pH.

The company running the former Piney Point plant, HRK Holdings, says water is leaking out of a pond inside a gypsum stack, which stores wastewater used in the production of phosphate fertilizer. The Department of Environmental Protection approved releasing an unknown amount of the water into Port Manatee, which leads into Tampa Bay.

Flue gas desulfurization (FGD) gypsum, a coal combustion by-product, can be used to decrease water-extractable soil P, thereby lowering the potential for P export to surface waters. This decrease results from a conversion of loosely bound inorganic P (IP) which is readily desorbable to water, to less soluble Al- and Fe-bound IP and, to a lesser extent, calcium-bound IP pools.

These tests provide an availability index of P in soils that relates to the phosphate fertilizer’s ability to provide an economically optimal increase in yield.
