What is VolcaMin?….. The mineral from the Volcano, (Zeolite Clinoptilolite) used in Horticulture e.g. in composts/potting mixes or growing media/or as a carrier/soil ameliorant. Also used as a Silicate Fertiliser, and are superior/excellent as a carrier for chemicals like Herbicides/insecticides/slow release natural fertilisers, e.g. holding Fish liquid, seaweed or chemical liquid fertilisers. The hard granules do not break down when swept or handled.

  2. Has broad range of Trace elements
  3. Inert: Will not react with other materials/liquids.
  4. Cation Exchange Capacity: (120 to 148CEC) for Nutrient retention, able to store and slowly release cations.
  5. Fusion Point: 1,570 deg. - 1,600 deg. centigrade
  6. Ideal pH = 6.5 (to 6.7pH)
  7. Non-Disaggregating: 
  8. Colour: Predominantly white and pink, minor grey
  9. Odour Control: absorbs, locks in and neutralises odours.



The VolcaMin minerals have been derived through in-situ from volcanic ash i.e. from a volcano.

Transformation processes have resulted in a tuff with an extremely porous structure. The high absorbencies suggest these minerals have very open frameworks. Dissolution and reprecipitation of amorphous silica has resulted in a 'welded' structure that does not disaggregate in water.


Mineralogically consists of quality Hydrated Calcium (Ca) Potassium Aluminosilicates essentially naturally amorphous silica mineral.


The 1mm-2mm Greens Grade Mini Prill grade has absorbencies that average 65 - 70% w/w.
