Cut YOUR Fertilizer costs by 30% TODAY! Proven to stop leaching of fertilizer from your soils. Great for row crops or pastures and can combined with Liquid 32 and other liquids in your sprayer or injector. Always bottle test first! Over 12% Liquid Humates or Humic Acid Remember it is NOT an acid - the pH is often above 9 pH. We carry 30, 55, and 275 gallon quantities. Liquid humic acid/liquid humate is a cost-effective way to add humus to your soil. Humic acid increases the efficiency of your fertilizers, transforms insoluble nutrients into useable ones, retards pathogenic fungi build-up, and stimulates microbial activity. This 100% natural, organic extract is made from West Texas leonardite ore deposits. From: http://en.wikipedia.org/wiki/Humic_acid#column-one Per Wikipedia: Humic acid is one of the major components of humic substances (or Natural Organic Matter (NOM)) which are dark brown and major constituents of soil organic matter humus that contributes to soil chemical and physical quality and are also precursors of some fossil fuels. They can also be found in peat, coal, many upland streams and ocean water. Humic substances make up a large portion of the dark matter in humus and are complex colloidal supramolecular mixtures (Piccolo, 1996, 2001; MacCarthy, 2001) that have never been separated into pure components. Since the end of the 18th century, humic substances have been designated as either humic acid, fulvic acid or humin. These fractions are defined strictly on their solubility in either acid or alkali, describing the materials by operation only, thus imparting no chemical information about the extracted materials. The term humic substances is used in a generic sense to distinguish the naturally occurring material from the chemical extractions named humic acid and fulvic acid, which are defined “operationally” by their solubility in alkali or acid solutions. It is important to note, however, that no sharp divisions exist between humic acids, fulvic acids and humins. They are all part of an extremely heterogeneous supramolecular system and the differences between the subdivisions are due to variations in chemical composition, acidity, degree of hydrophobicity and self-associations of molecules. When humic substances are characterized, especially when functionality is studied, there is always the problem that one usually has to separate the huge number of different bioorganic molecules into homogenous fractions. Humic substances arise by the microbial degradation of biomolecules (lipids, proteins, carbohydrates, lignin)dispersed in the environment after the death of living cells. A modern structural description regards humic material as a supramolecular structure of relatively small bio-organic molecules (having molecular mass <1000 Da) self-assembled mainly by weak dispersive forces such as van der Waals,π-π, and CH-π bonds into only apparently large molecular sizes (see http://www.suprahumic.unina.it/). A large amount of humic molecules are represented by hydrophobic compounds (long alkyl-chain alkanes, alkenes, fatty acids, sterols, terpenoids, and phenyl-alkyl residues of lignin degradation) which allow their self-association into supramolecular structures separated from the water medium and, thus, their long residence time in the environment. Humic substances are endowed with acidic functional groups mainly carboxylic acid, which confer on these molecules the ability to chelate multivalent cations such as Mg2+, Ca2+, and Fe2+. This chelation of ions is an important role of humic acids with respect to living systems. By chelating the ions, they facilitate the uptake of these ions by several mechanisms, one of which is preventing their precipitation, another seems to be a direct and positive influence on their bioavailability.
