What is Gypsum & What does it do?
Gypsum is a naturally occurring calcium sulphate dehydrate (CaSO42H2O), when applied to soil it dissolves in rain or irrigation water to interact with the fine clay particles. As the Gypsum dissolves it acts as a flocculating agent on finer soil particles forming crumbs so that the soil becomes better aerated and gives a greater water holding capacity. This improves soil structure making the clay more stable when wet and reducing the tendency of soil surfaces to set hard when dry.

Some of the benefits of Gypsum use include;

Soil becomes better aerated making cultivation easier and cost effective improving germination and reducing erosion.
Gypsum will maintain soil structure by inhibiting dispersion. It is the calcium in Gypsum which replaces sodium in the soil (by ion exchange), consequently crusting is reduced. This also allows the sodium to be leached or washed out of the soil without altering the PH level.
Adding Gypsum assists with water drainage to increase water storage by causing swelling in the soil and dispersion of clay.
