Nutri-Mate Organic Humates

Raw humates still contain all of the dense mineralisation and organic acids found in the prehistoric plants from which they are deprived. The life force from those nutrient-dense plants lives on in lignite and leonardite.

These lignite-based humates from Victoria's Latrobe Valley contain 67% organic carbon and 40% humic acid in slow-release form. Raw humates are recognised as the most effective of all soil conditioners. They are unique in comparison to the processed humates in that they still retain the insoluble humin fraction. Humins are where most of the dense mineralisation occurs. Nutri-Mate Humates contain seventy minerals, many of which are lacking in our agricultural soils.


  • Nutri-Mate has a very high Cation Exchange Capacity (250), with an associated ability for nutrient and moisture retention.
  • Nutri-Mate contains the highest organic carbon levels of any input. Organic carbon is the principle limiting factor in many soils.
  • Organic carbon is the home base for beneficial micro-organisms.
  • Nutri-Mate Organic Humates deliver slow-release humic acid, at a price that equates to a few cents per litre.
  • Nutri-Mate is a highly effective soil conditioner, largely due to its stimulation of fungi which generate desirable crumb structure in the soil.
  • Raw humates are a powerful fungi stimulant. The amino acids, complex carbohydrates and low pH comprise perfect fungi food.
  • Nutri-mate offers all of the many benefits of humic and fulvic acid, but these materials are trickle-fed over a two-year release pattern.
  • Biological Farmers of Australia (B.F.A.) Registered Product 456AI.

  • Nutri-Mate Organic Humates do not offer the equivalent stabilising and magnifying effect of Soluble Humate Granules but do offer a more dense mineral spectrum, ie. Nutri-Mate Organic Humates still contain the high levels of broad-spectrum minerals that were part of the ancient plants from which they are derived.
  • Nutri-Mate is a key ingredient in the Life-Force™ blends.
