Gypsum powder is used in agriculture as a soil amendment and a source of calcium and sulfur for plants. It improves soil structure, particularly in heavy clay soils, by promoting aggregation and increasing water infiltration. Gypsum also helps reclaim sodic soils and can mitigate subsoil acidity and aluminum toxicity, benefiting plant growth. Improved Soil Structure: Gypsum helps to break down heavy clay soils, making them more porous and allowing for better aeration and drainage. Enhanced Water Infiltration: By improving soil structure, gypsum allows water to penetrate deeper into the soil, reaching plant roots more effectively. Reduced Runoff and Erosion: Gypsum helps prevent surface sealing, reducing runoff and erosion, which can carry away valuable nutrients and soil. Mitigated Subsoil Acidity: Gypsum can help neutralize subsoil acidity, reducing aluminum toxicity, which can hinder plant growth.
