Humates, which are composed of various forms of carbon, and are naturally occurring material that is very rich in humified organic matter and humic substances. Humates are now recognised as one of the single most productive inputs in sustainable agriculture. It has become a main ingredient to increasing yields in many agricultural areas around the globe.

General application rates for humate powder are 500-1000kg/ha, however a soil test is recommended before applying the product.  Humates do perform better when applied with products such as lime or gypsum and soil test will help with a blend formulation.

Humates perform well in blends with ag lime, gypsum, phosphate rock and manures. Pacific Fertiliser can provide these humate blends in powder or granular form.

The humates fines which we use for our products were formed some 20 million years ago. Leonardite (brown coal) is an organic matter associated with lignite that has not yet completed the process of transformation into coal. Humates originally formed as peat from decomposed forests and plants became more and more compressed. Australian humate contains almost 60% concentrated organic matter. The humates are highly water soluble so that the Humic Acid can properly move through the soil, chelate with other salts, minerals and fertilisers, stimulating microbial responses.

Humic Acid 54%
Fulvic Acid 44%
