Role of Gypsum as a Soil Amendment!
Gypsum has been applied to agricultural land throughout the San Joaquin Valley and, elsewhere, to improve and maintain irrigation infiltration rates.The basic two types of Gypsum used in soil amendments are, natural gypsum mined from geologic deposits and recycled drywall gypsum. The mineral purity of the natural gypsum will very with the geology and the mining technology employed at the site. The mined product based on the process can be used either as broadcast or solution application. The recycled drywall material is crushed and sorted through a screening process to remove all foreign metals resulting in a clean product for broadcast application.
