Clay Soils – 1 to 2 kg per square metre. Break up clods, spread the gypsum and dig it into the soil. Where digging is not practical, spread over the surface and water in.
Gypsum works best on sodic clays that disperse when wet. It will not improve every clay soil. Water in well after applying.
Wear gloves when handling and wash hands after use.
