Kieserite Magnesium Sulphate Granular Ref #MGG/25, MGG/BB

Ref #MGG/25, MGG/BB


Kieserite is a naturally occurring mineral that is chemically known as magnesium sulphate monohydrate.  It is mined from ancient marine deposits and used in the agricultural industry as a fertiliser source for magnesium and sulphur.  Kieserite is slowly water soluble and suitable for soil application to a wide range of horticultural and broad acre crops.  Kieserite is not suitable for fertigation or foliar application.

  • In granular form is suited for blending with other granualr fertilisers for custom blends
  • Dissolves slowly with soil mosture to better match ongoing plant demand
  • Will not leach as quickly as soil applied magnesium sulphate heptahydrate
  • Supplementing magnesium will increase chlorophyll production and increase photosynthesis in plants
  • Ideal for use on crops grown in low magnesium soils to increase productivity
