Gypsum (CaSO 4 ·2H 2 O) is a natural mineral. It is, however, also well known as a by-product (co-fertilizer material) of technologies producing phosphate fertilizers (Parrish and Ogilvie 1939; Kongshaug et al. 2000), technologies used for the production of TiO 2 (Gázquez et al. 2014), and others.From the "non-chemical" …
A high-purity grade of ammonium sulfate often works best for this purpose to avoid plugging spray nozzles. Management practices. After addition to soil, the ammonium sulfate rapidly dissolves into its ammonium and sulfate components. If it remains on the soil surface, the ammonium may be susceptible to gaseous loss in alkaline conditions.
