Humic and Fulvic acids are the final break-down constituents of the natural decay of plant and animal materials. These organic acids are found in pre-historic deposits. Humic matter is formed through the chemical and biological humification of plant and animal matter and through the biological activities of micro-organisms. Humic acids are complex molecules that exist naturally in soils, peats, oceans and fresh waters. The one source of humic acids are the sedimentation layers referred to as Leonardite. These layers were originally deep in the earth’s crust, but over many years have been exhumed to near-surface location. Humic acids are found in high concentration in these layers.
Leonardite is organic matter, which has not reached the state of coal and differs from soft brown coal by its high oxidation degree, a result of the process of coal formation, and has no value as fuel. The decomposition of concentrated organic acids is a lengthy process taking millions of years in the natural environment. Imagine, if you will, a prehistoric marsh or peat bog. Plants are harvesting carbon dioxide from the atmosphere and using the sun’s energy to build plant biomass. These plants feed insects and vertebrates. As plants and animals die they contribute their carbon back to the bottom of the bog. Over millions of years this cycle of organic matter is concentrated and compressed into layers in the earth.
What Is It Used For In Agriculture?
Leonardite is not a fertilizer. It acts as a conditioner for the soil and as a bio-catalyst and bio-stimulant for the plant. 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. Compared to other organic products, Leonardite enhances plant growth (biomass production) and fertility of the soil. Another advantage of Leonardite is its long-term effectiveness, as it does not get consumed as quickly as animal manure, compost or peat. Leonardite decomposes completely, therefore it does not enter into nutritional competition with plants for nutrients like nitrogen. This is not the case with partially decomposed compost, whereby the organic substances in soil are rapidly consumed by microorganisms and mineralized entirely without humus formation.
