KMS is a natural, unique fertilizer product containing three essential nutrients Potassium, Sulphur and Magnesium:

K = Potassium 20% in non-chloride form
S = Sulphur 16%
Mg = Magnesium 7%

All three nutrients are present in the highly available water-soluble form. 

The continuous release rate (dissolves slowly) of potassium, sulphur and magnesium reduces and resists leaching losses making it a highly effective nutrient efficient fertilizer, with good environmental performances.

KMS = Yield and Quality = Sustainability = VALUE = Profitability



KMS Fertilizer is a highly available fully water soluble and bioavailable form of Potassium, balanced with Magnesium to aid in chlorophyll production with Sulphur to assist in enzyme activation.  As a result KMS is being recognised for the multitude of other advantages which flow on from this naturally unique product:

  • The unique 3 in 1 combination of these nutrients helps maintain nutrient balance particularly where high analysis fertilizers don't replace magnesium and sulphur lost from the soil each year.
  • In comparison to most other KSMg based fertilizers KMS Fertilizer has a lower Magnesium level, making it more suitable to a broader range of soils.
  • KMS is particularly suited for horticultural crops and dairy pastures via direct application or in a blend to enhance the effectiveness of the other fertilizers and animal nutrition in the case of dairy pastures.
  • KMS can readily replace traditional Potassium based fertilizers such as MOP with the advantage of reduced Chloride levels (50% vs 1.5%).
  • KMS in Organic Farming allows for higher inclusion rates of K as opposed to SOP.
  • Ideal product for Specialised Custom Blending with Guano Gold-Kwik Start, AmSul, DAP, MAP, MOP, SOP and/or other related products. Guano Gold/KMS Blends Chart
