Overview

Gypsum is one of the earliest forms of fertilizer used in the United States. It has been applied to agricultural soils for more than 250 years. Gypsum is a moderately soluble source of the essential plant nutrients, calcium and sulfur, and can improve overall plant growth.

Benefits

Gypsum is an excellent source of calcium. Calcium is an essential nutrient for plant growth and development, particularly for roots and shoots. It also acts as a balancing element, improving a plant’s ability to take in other essential nutrients such as ammonium nitrogen.
