In addition, gypsum’s solubility promotes soil porosity which enhances water infiltration. Also, the application of gypsum enables fibrous root crops such as wheat and corn to root deeper and better absorb nutrients. Gypsum changes the soil composition through a process called flocculation. The gypsum enables the small and dense clay particles to join together to form bigger particles, more closely resembling loose sand2. Another occasion when gypsum is often introduced in a garden setting is if the soil in your garden lacks calcium. Gypsum is more water soluble than lime at a pH above 6.0 and will give you a faster response.
