Agricultural Gypsum is a CE fertiliser grade gypsum obtained from naturally occurring mineral. It is used in a variety of agricultural applications including as a carrier for horticultural dressings, as a mushroom composting ingredient, as a soil improver and in land reclamation after salt water flooding

Application Guide for Clay Soils:For heavy clay soils, an application rate of approximately 500gm per square metre is required which can be applied by hand or by lime spreader.For best results, the gypsum should be intimately mixed with the top 5 cm of soil, which should give an improved soil structure helping aeration and drainage and also improving plant growth.Calculated minimum content of nutrients (% by weight):SO3 = 27%CaO = 39%
