Gypsum (calcium sulphate di-hydrate) is an abundant natural mineral. It originates from the drying out of ancient seas
and is quarried (or mined if deep) in many parts of the world. Gypsum does not occur in New Zealand. Winstone imports
our gypsum from Australia.
Gypsum enjoys a growing application in agriculture and horticulture. It is used as a 'clean green' soil conditioner and
also as a fertiliser. Gypsum has an advantage over certain other minerals of being pH neutral.
Gypsum is particularly useful for treating heavy (clay) soils where it is used to improve the soil's texture, drainage
and aeration. Gypsum also has applications in the remediation of soil that has been damaged through compaction (heavy
stock, machinery), in the recovery of sub-soils exposed by earth movement (contouring, slippage) and in soils affected
by salinity (estuarial berms, dairy effluent).
Gypsum is also used extensively in the building industry (wallboards, cements, plasters etc) and in the manufacture
of paper, food and beverages and pharmaceuticals.
