What is Humic Acid?

Humic acids (HA) are high molecular weight, polydisperse, multifunctional natural organic compounds. They are formed from plant residues in different natural environments as a result of a long process of humification.

Until recently, commercial humic fertilizers were produced either as liquids, or as powders, with varying degrees of water (rarely with more than 20% humic acid content).

What is Liquid Humic Acid?

Liquid Humic Fertilizers are a concentrated solution of humates (potassium, sodium, less frequently ammonium salts of humic acids), obtained by a prolonged alkaline extraction at heating for 2-24 hours from the raw materials: peat; lignite and coal; vermicompost, sapropel, waste from wood and pulp industry. The resulting solutions have a highly alkaline reaction (pH ranging from 9 to 14).

This method of production has been present for over 50 years, and today, it’s most popular. The main advantage of liquid humic fertilizers is that HA content is at its most active and bio-available state.

What is Powder Humic Acid?

Powder Humic Fertilizers are a finely ground mixture of alkali (KOH, NaOH) and coal (lignite) in the ratio range of 1/10 – 1/50. The introduction of salts during the preparation of the working solution allows for the cold extraction of HA and pro-huminous organic compounds to the final mixture. The main advantage of this type of production is its low cost of production and the possibility to prepare a highly concentrated mix in organic matter, not in HA (up to 120-130 g/l).

What is Humic Land?

It is a soil amendment made from peat, using cavitation and fine grinding without any chemicals used in the production process. The resulting product is a peat gel. Humic Land’s dispersion medium is water, which permits a constant neutral pH ranging between 5 and 7.

This process gives Humic Land’s high concentration of HA and FA (Fulvic Acid); in the form of individual particles, (molecular associations).

Contrary to Liquid Humic Acids, which offer the most active and bio-available state of HA at the time of use, followed with a sharp decline in vegetation stimulation, Humic Land gel offers the soil smaller levels of active/dissolved HA substances (9%). The active surfactants, HA and FA, reduce the surface tension of aqueous solutions, increasing the permeability of the cell membranes. It optimizes the capacity of the transport system of the plants, which accelerates the movement of nutrients. This acceleration has a direct effect on the plant’s metabolism. The rate of photosynthesis and the synthesis of chlorophyll over a more prolonged and continued period.
