To make soil suitable for cropping, gypsum is typically used to treat alkaline soil. Alkaline soil is characterized by a high pH level, usually above 7. This type of soil often contains high amounts of calcium carbonate, which can hinder the growth of plants by reducing nutrient availability. Gypsum, also known as calcium sulfate, helps to reduce the pH level of alkaline soil and improves its structure. It does this by replacing the calcium carbonate with calcium sulfate, which is more soluble in water and allows for better nutrient absorption by plants. The application of gypsum also helps to improve the drainage and aeration of the soil, promoting healthy root growth.
