Gypsum

Gypsum (calcium sulphate) when applied to soil dissolves in rain and or irrigation water and interacts with the fine clay particles. This interaction improves soil structure making the clay more stable when wet and reducing the tendency of soil surfaces to set hard when dry. Sloppy mud from the untreated area (above) contrasts with well-structured friable soil after a gypsum application.

Gypsum can be used for a variety of applications including broad acre crops, small farms, vineyards, orchards and sports and recreation fields.
