Gypsum has been widely used in agriculture in the United States and New Zealand for many years principally to:-

  • Add calcium without raising the pH of the soil
  • For crops that require higher levels of Sulphur and / or Calcium
  • On light sandy soils that do not hold nutrients
  • On crops that require acidic soils
  • To obtain calcium and sulphur in their most soluble form
  • To improve the calcium / magnesium ratio
  • To correct salt damage
  • To help in waterlogged areas

Typical Analysis

Calcium 22%
Magnesium 0.2%
Sulphur 19%
Boron 6 ppm
Iron 500ppm
Manganese 10ppm
Phosphorous 50ppm

Gypsum is highly soluble; therefore it is an excellent source of Calcium and Sulphur, especially for acid loving crops.
