When this substance is ground into a fine powder, it can be used as an amendment to improve soil structure and fertility. Gypsum works by loosening compacted soil and increasing the amount of air and water that can penetrate in it. This allows roots to grow more easily and access the nutrients with ease. Additionally, gypsum can help neutralize the pH of acidic soils by increasing their calcium content.
