Gypsum is the most commonly used amendment for sodic soil recla-mation and can be included as a component in synthetic soils used in nursery, greenhouse, and land-scape applications. Sep 9, 2023 · Gypsum can also improve soil structure by displacing sodium ions in sodic soils. Chemical Impurities: While the chemical formula for gypsum is relatively simple (CaSO4·2H2O), natural gypsum deposits may contain impurities, including small amounts of other minerals or elements. Gypsum can help loosen clay soils and improve soil structure by transforming fine, tightly packed particles into larger clumps that make the soil more porous, allowing air, water and nutrients to penetrate the soil more easily. This also helps to encourage better root development, resulting in stronger, healthier plants. To test this hypothesis, we used successive applications of gypsum or epsom, with and without Hi-Cal or dolomitic lime, to either increase or lower soil Ca:Mg ratio in an Ohio soil planted to a corn (Zea mays L.)–soybean (Glycine max L.)–cereal grain rotation and measured the effect on soil properties and crop yields.Oct 23, 2019 · Adding gypsum to lawns is not straightforward.
