Key Observations

This NSA Humate sample was analysed for its chemical properties to determine its nutrient contribution. It has a high acidic pH in CaCl2 and moderate salinity levels but low sodium and chloride levels. Therefore this material would work best on alkaline soils. The cation exchange is dominated by hydrogen which explains the strong acidity and the availability of aluminium.

Organic matter = 58.4%

Fractionated as:

Humic Acid = 32.3%

Fulvic Acid = 4.8%

Humin = 62.9%

The high eCEC indicates a high nutrient retention and holding capacity, meaning that this product will enable soils to better hold on to fertiliser applications, providing improved value from each application.

As well as providing a high carbon/organic source, this material will also provide a good source of nitrogen.
