Characteristics of Humic Acids | Previous | Index | Next

It is now recognized that humic acids are complex molecules formed by the breakdown of organic matter. The molecular weight of humic acids can vary between 5,000 and 50,000 with various organic groups present.

Humic substances participate actively in the decomposition of rocks and minerals and promote the conversion of a number of elements into forms available to plants. Many studies have demonstrated that humic substances increase the germination capacity of the seed and enhance the vitamin content of plants. These studies suggest that humic acids and their derivatives increase the permeability of plant membranes in order to promote the uptake of nutrients. At the same time, humic substances positively effect the growth of various micro organisms which promote plant development.
