Field application of gypsum (CaSO4 × 2H2O) is a tool to decrease phosphorus (P) load to watercourses. Effects of gypsum application (4 tons ha-1) on soil and crop composition were monitored up to four years after the treatment in the Savijoki catchment, southwestern Finland. Eleven amended fields and 17 control fields were …

Non-volatile; easy to apply with no nitrogen losses to the atmosphere. The presence of nitrate in Multi-K® enables the plant to minimize its uptake of chloride, whenever this deleterious anion is present in the soil solution or in the irrigation water. This makes Multi-K® a necessity for chloride-sensitive crops. Product Number: 10418.

Typically, plants produce most of the energy they need and some sell a portion to the area commercial energy provider. When sulfuric acid is reacted with phosphate rock to produce phosphoric acid, a by-product calcium sulfate (gypsum) is also produced. This by-product gypsum is called phosphogypsum.

Gypsum is calcium sulfate (CaSO4•2H2O) and contains about 22 percent calcium and 18 percent sulfur. There are reports of gypsum being used as a soil amendment or fertilizer dating back to Benjamin Franklin (1740 - 1760). While the primary users of mined and synthetic gypsum are the wallboard, plaster and cement industries, agricultural use ...

Gypsum, also known as calcium sulfate, is a popular choice. It adheres well to clay particles and dissolves slowly, providing a ready source of calcium for your plants. Lime is another choice. Also known as calcium carbonate, it increases the alkalinity of your soil, which is often necessary if you have a calcium deficiency.

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.
