Also known as SOP and or Potasium Sulphate
SOP is a Potassium source which has a low Salt index. It is ideal for Salt sensitive crops.
In NZ, SOP has traditionally been used in Horticultural and market garden-based crops such as potatoes. It is now used by pastoral farmers who are wishing to apply a low Salt index potassium while also applying the key nutrients of Sulphate Sulphur.
SOP serves as a Potassium source with a low Salt index and is ideal for Salt sensitive crops that also require Sulphur.

SOP can be mixed with most fertilisers however care should be taken around bulk densities.
