Gypsum (Calcium Sulfate) 0-0-0 23Ca 17S

An outstanding soil supplement for soil lacking calcium, but the pH is adequate or high. Gypsum will loosen the soil, encourage soil life, and add the needed calcium. Calcium also acts as a weed deterrent as most weeds prefer acid soils. The sulfur when combined with water will form a weak sulfuric acid which will release calcium that is tied up in the soil solution. This is quick reaction product.
