Agricultural Gypsum (Calcium Sulfate – CaSO4) is one of those rare materials that performs in all three categories of soil treatment: an amendment, conditioner, and fertilizer.
Soil conditioners, such as gypsum, are seriously undervalued compared to fertilizer usage.
Let’s look at it from the plants point of view. The bottom-line question here is AVAILABILITY. How much calcium sulfate (nutrition) is available to the plant to meet its gypsum requirement when it needs it? The same is true with the soil. If it does not get gypsum when it needs it, the soil may compact, prevent water and air penetration, lose its leaching ability and become saturated with salt or other excessive elements harmful to plant growth and health. Then the plant suffers from bad soil conditions.
Poor soil structure is a major limiting factor in crop yield. The bottom line to the many benefits of gypsum is higher yield at a minimum cost.
