Gypsum (CaSO4· 2H2O) is a soft white, grey, brownish or slightly pink mineral consisting of hydrated calcium sulphate also know as calcium sulphate di-hydrate. It occurs mainly in sedimentary deposits and is used to for soil amelioration and in building construction materials. Gypsum is moderately water-soluble (~2.0–2.5 g/l at 25 °C) and, in contrast to most other salts, it exhibits
Putting the dollars into sodic soil management Key Points of the GRDC article: - Sodicity is the presence of too much sodium (Na) in the soil. - Australia represents the majority of the world’s sodicity issues which can lead to a reduction in plant growth and grain yield as well as decreased soil structural ability.
Pacific Fertiliser Gypsum Is Almost A Universal Soil Amendment Irrigated land eventually leads to sodicity and salinity unless extreme care is taken. Gypsum is a key ingredient for the maintenance of agriculture on many types of soils and over a wide pH range including sodicity. Advantages of Pacific gypsum in addition to prevention and correction
