The organic gold Leonardite is organic material that has not reached the coal stage yet. The difference from Lignite by its higher degree of oxidation in the coalification process, higher humic acid content and a higher number of carboxyl groups.
Disparity other organic sources of humic acid, Leonardite is highly bioactive due to their molecular structure – up to four-five times more than common humus components. Leonardite is not a fertilizer. It acts as a soil conditioner for plants. In comparison to other organic products, Leonardite particularly promotes plant growth and soil fertility.
Another advantage of Leonardite is its long-term effect. It is degraded more slowly than, for example, manure, compost or peat because it contains more organic matter that is also more resistant to decomposers.
