Gypsum helps soil better absorb water and reduces erosion.
It also cuts down on phosphorus movement from soils to lakes and streams and improves the quality of various fruits and vegetables, among other benefits."
"The gypsum particles are small and uniform in size making them quite reactive.
We also determined that it is safe for agricultural use through many studies.
In addition, the chemical formula of gypsum makes those nutrients more available to plants than some other common sources of these nutrients.
Gypsum will change soil pH very slightly, yet it can promote better root development of crops, especially in acid soils, even without a big pH change.
