There has been much interest in the subject of soil humus and humates over the years. There is basic agreement on the benefits of humus. Humic acids are reported to increase the permeability of plant membranes, so promoting the uptake of nutrients. There is evidence of a positive effect of humic acid substances on the growth of various groups of microorganisms. There is also evidence that some of the humate materials contain large populations of Actinomycetes (microorganisms that share the properties of both fungi and bacteria). They are capable of degrading a wide range of substances including celluloses, humicelluloses, proteins, and lignin.
The coal-humic fertilizers activate the biochemical processes in plants
(respiration, photosynthesis and chlorophyll content) and increase the
quality and yield of many crops. It is clear that humic acids are a benefit
to the farmer.

HUMIC ACID WORKS WITH FERTILIZERS
TO PRODUCE BETTER CROPS |
| HUMIC ACIDS are extracted from ground Leonardite,
an oxidized form of lignite, and are the principal constituents of organic
vegetable matter in an advanced state of decomposition.
Humification thus is an evolving process where organic matter is being changed, first as young Humus, becoming stable Humus and finally mineralization that makes humic acid. Humic acids derived from Leonardite are quite stable, their oxidation grade and components are uniform. Humic acids have two main components: humic acid and fulvic acid, in different proportions according to their origin and extraction method. The mixture of these acids is generally known as humic acid, because of its universal connotation with the humic concept that describes maximum fertility and optimum soil condition. |
