HUMIC ACID

What is Humic Acids and what is it's sources?

Humic matter is formed through the chemical and biological humification of plant and animal matter and through the biological activities of micro-organisms. The biological content, the main fraction of natural humic matter, are the humic acids, which contain humic acid and fulvic acid. Humic acids are an excellent natural and organic way to provide plants, and soil with a concentrated dose of essential nutrients, vitamins and trace elements. They are complex molecules that exist naturally in soils, peat, oceans and fresh waters. The best source of humic acids are the sedimentation layers of soft brown coal, which are referred to as Leonardite. Humic acids are found in high concentration here. Leonardite is organic matter, which has not reached the state of coal and difference from soft brown coal by its high oxidation degree, a result of the process of coal formation (bog>peat>coal), and high humic acids content as well as higher carboxyl groups.

Compared to other organic products, Leonardite is very rich in humic acids. While Leonardite is the end product of a humification process lasting 70 million years, the formation period of peat, is completed within only a few thousand years. The difference between Leonardite and other sources of humic acids lies in its property that Leonardite is extremely bioactive through its molecular structure . This biological activity is about five times stronger than other humic matter.

Leonardite is not a fertilizer. But it acts as conditioner for the soil and as bio-catalyst and bio-stimulant for the plant.

HUMIC
Compared to other organic products, Leonardite enhances plant growth particularly (biomass production) and fertility of thesoil. Another advantage of Leonardite is its long-term effectiveness, as it does not consume up so quickly as animal manure, compost or peat. As Leonardite is completely decomposed, it does not enter into nutritional competition with plants for nutrients such as for nitrogen. This is not the case with incompletely decomposed compost, whereby the organic substances in soil are rapidly consumed up by micro-organisms and mineralized entirely without humus formation.
