Gypsum, a mineral with high levels of calcium, is a versatile soil amendment commonly used in agriculture. When applied to soil, gypsum helps to improve soil structure, making it more friable and less prone to compaction. This benefits plants by allowing better root penetration and access to nutrients. Additionally, gypsum aids in water infiltration and drainage, reducing the risk of waterlogging and excess water accumulation, which can be detrimental to plant health.

By promoting better soil aeration and nutrient uptake, gypsum fosters improved crop growth and yield. Some gardeners also use gypsum in combination with a spike aerator to enhance soil aeration further. Moreover, gypsum can help plants in the process of photosynthesis by providing essential calcium and reducing the effects of excessive carbon dioxide. Overall, the use of gypsum contributes to healthier soils and improved crop production.
