What is Humic Acid ?

The active compounds in humus that acts as soil conditioner are Humic Acid and Fulvic Acid. These stable organic compounds are the final products of the decomposition of organic matter.

Humic Acid and Fulvic Acid are different from the organic compounds found in other organic fertilizers such as compost and manure, which contain other types of compounds that are easily degradable by microbes in the soil and will eventually run out.

Humic Acid is an organic polymer compound with a complex macromolecular structure, a high molar mass and several working groups. In nature, Humic Acid is formed through a set of physical, chemical and biological processes in plant and animal matter, called humification. Because the structure is a mixture of aliphatic and aromatic compounds (which include the working groups carboxylic acid and quinoide), Humic Acid has the ability to stimulate and activate biological and physiological processes in soil microorganisms. Fulvic Acid has a shorter polymer chain, and can dissolve in all pH ranges, making it more reactive.

Other important characteristics of Humic Acid and Fulvic Acid that are connected to their role in improving soil condition and plant growth are their high Cation Exchange Capacities, high water holding capacities, adsorption abilities, the ability to act as chelating agents and the ability to fixate pollutants in soil.

With these advantageous attributes, Humic Acid can be used to increase productivity and quality of plants in agriculture, plantation and forestry, to increase soil fertility, to improve conditions in degraded land and to reduce the use of inorganic fertilizers, which is less damaging to the environment in addition to being more economical.
