Potassium humate is the potassium salt of humic acid. It is manufactured commercially by alkaline extraction of brown coal (lignite) Leonardite to be used mainly as a soil conditioner. The extraction is performed in water with the addition of potassium hydroxide (KOH), sequestering agents, and hydrotropic surfactants. Heat is used to increase the solubility of humic acids and hence more potassium humate can be extracted.
Potassium Humate is potassium salt of humic acid from high-grade Leonardite. It is a high-quality plant stimulant and soil conditioner and can be applied in landscape and gardens as well as for all agricultural and horticultural plants. It also could stimulate seed germination. With high concentration of humic acid, it could be stored and transported easily. Its solubility is excellent, and could be formulated by different fertilizers and pesticides.
Advantage:
Foliar Application:
Stimulate plant growth (increased biomass production)
Increase yield and improves quality of plants
Improve nutrient uptake through the leaves and roots
Improve the effectiveness of pesticides
Soil Application:
Improve the soil structure
Reduce nutrient losses
Improve nutrient uptake by the root system
Promote root development
Increase microbiological activity of soil
Increase capacities of water holding and cation exchange
The resulting liquid is dried to produce the amorphous crystalline-like product which can then be added as a granule to fertilizer. The potassium humate granules by way of chemical extraction lose their hydrophobic properties and are now soluble. Depending on the source material product quality varies. High-quality oxidized lignite (brown coal), usually referred to as leonardite, is the best source material for the extraction of large quantities of potassium humate. The less oxidized the coal the less potassium humate extracted.
Sources low in ash produce the best quality. Less oxidized brown coal contains a higher proportion of the insoluble humin fraction and along with peat which is lower in humic acid content and usually high in ash content requires separation by filtration or centrifugation to remove ash, humin. Peat is also high in non-humified organic matter that needs to be reduced to produce a high-quality product.
The benefit of peat is that it is usually 2-3 times higher in fulvic acid content, which are the low molecular weight fractions of humic acid that are high in oxygen-containing functional groups and soluble at a low pH of <1. Fulvic acids have a higher cation exchange capacity and therefore have a higher chemical interaction with fertilizers and are able to form soluble chelates of trace metals.
It is used in agriculture as a fertilizer additive to increase the efficiency of fertilizers especially nitrogen and phosphorus-based fertilizer inputs. Other salts of humic acid are manufactured, mainly sodium humate which is used in animal health supplements. It also can be used in Aquaculture.
