Natural Gypsum Fertilizer & Soil Conditioner CalciSoil® gypsum is an agricultural grade gypsum mined from naturally occurring ocean deposits formed centuries ago. It acts as a soil amendment by reducing soil compaction and flocculating dispersive soils, thereby it loosens heavy/hard clay soils and improves water infiltration into subsoil. Reducing soil salinity as well as aluminum toxicity are among other benefits of CalciSoil® gypsum. It is a fertilizer too, since it contains essential micronutrients calcium and sulfur; CalciSoil® gypsum helps correct sulfur deficiency without changing soil pH. Features: Neutral pH High purity Free of Moisture Natural Mineral Easy to spread High whiteness Usage: For use in agricultural crops (paddy rice, tomatoes, potatoes, groundnuts, mushrooms, corn, sugarcane etc. ); for lawn, turf, golf course and landscaping; for clearing muddy ponds and many others.
