Arizona's Best AZB40012 Gypsum Soil Amendment, Solid, White, 40 lb

Arizona's finest gypsum contains calcium and sulfur, helping to neutralize soil alkalinity, loosening compact soils and assisting in increasing water penetration and encouraging deeper root systems. Because of its natural slow-release characteristic, gypsum can be used any time of year either as a pre-plant soil amendment and used after planting.
