Gypsum

Gypsum is a naturally occurring mineral composed of calcium sulfate dihydrate (CaSO₄·2H₂O). It is widely used as a soil amendment in agriculture to improve soil structure and fertility. Gypsum helps to:

• Improve soil aeration and water infiltration by breaking up compacted soil layers.

• Provide essential nutrients such as calcium and sulfur, which are vital for plant growth.

• Reduce soil alkalinity and help in reclaiming sodic soils by displacing sodium ions.

• Enhance root development and nutrient uptake in crops.

• Reduce phosphorus fixation in soil, making phosphorus more available to plants.

Gypsum is especially beneficial for crops grown on clayey or alkaline soils and can improve yield and quality in crops like wheat, rice, sugarcane, cotton, and vegetables.
