Gypsum as a natural soil conditioner

Gypsum is a slow release source of sulphur and calcium which can be used to improve soil structure, aeration and water retention of clay soils. Reduced crusting of the soil surface allows for better water penetration and the improved soil structure allows for better root penetration. Plants need sulphur, gypsum contains 18%, and being a neutral mineral it won't upset the soil's pH balance. Gypsum can be incorporated into the planting bed at 1-3kg per sq. metre prior to planting, or used as a top-dressing at half kg per sq. metre. Gypsum is cost effective.
