NTS Granular Humic Acid™

A processed concentrate containing humic acid in slow-release, granulated form. These humates are delivered in convenient 2-4 mm granules, containing 70% humic acids.

Benefits and features

  • Biological Farmers of Australia (BFA) Registered Product 456AI.
  • Offers all the numerous benefits of humic acid in a slow-release form.
  • Slow-release humic acid can help to stabilise inputs throughout the crop cycle.
  • This product still retains the high levels of broad-spectrum minerals that were part of the ancient plants from which it was derived.
  • Humic acid is a powerful fungi promotant. Beneficial fungi are the missing link in many soils.
  • Stabilises nitrogen and improves nitrogen efficiency.
  • Complexes phosphate to reduce lock-ups.
  • Natural chelating and complexing agent to help magnify nutrient absorption.
  • Increases the permeability of cells to increase nutrient uptake by up to 40 %.
  • Contains an auxin-like growth promotant that can enhance cell division and elongation.
  • Can buffer the effects of excessive elements (particularly sodium), toxic chemicals and heavy metals.
  • pH buffering capacity to help neutralise the problems associated with pH extremes.
  • Promotes seed germination in a shorter time.
  • Has a nature which assists in soil wetting.
  • Promotes soil structure improvement by promoting fungi to create a crumb structure for better water and oxygen intake and improved root penetration.
  • Microbe-friendly.
  • Can be applied directly to the soil at any time to help buffer excesses or toxins or to promote soil life (fungi).

Dr Elaine Inghams Research and Technical Advice on Humic Acids:

Complex, highly condensed organic matter, with a high molecular weight which results in a deep, rich dark brown colour to these products.

Depending on the exact structure of the molecules, humic acids bind salts, heavy metals, toxics, pesticides, and a variety of other reactive or ionic materials. Estimates have been made that each 1g of humic acid material can tie-up 1mg of ionic material. This means that the toxic material is no longer plant available. The benefit of having complex, highly condensed organic matter is readily apparent. The amount of humic acid material and thus the ability of that material to bind ions depends on the original source of plant material.

Typically humic acids are extracted with very strong acids and bases from leonardite, which is soft, brown coal. These strong acids and bases have to be neutralised before addition of the micro-organisms, or the acids and bases will harm the organisms. In addition, the humics extracted are denatured by the acid base reflux used, and thus the best products for growing microbes re-nature the humic acids before use.

If the pH of the product is very acidic or basic, the material needs to be brought to neutral pH before use. If pH is not adjusted, then the organic material will need processing by microbes before benefit will be apparent.

Fungi do the most work in the condensation processes of building highly complex materials like humic acid, although microarthropods, earthworms, protozoa and bacteria are also needed for full diversity of good humic materials.

As fungi decompose humic acids, they release simpler compounds, so of which are bacterial foods. Thus most humics haveboth a fungal and a bacterial growth response.
