Humic acid is formed by microbial degradation of the dead biological substances.
Its specific properties and structure depending on a given sample source from water or soil to extract the specific conditions.
Products we have are humic acid powder, granular humic acid and humic acid crystal.
Humus in soils and sediments can be divided into three main parts: humic acid (HA), fulvic acid (FA) and humin (HM).
HA is soluble in alkali solution, but not soluble in water and acid, FA is soluble in alkali, soluble in water and acid; the HM is neither soluble in alkali, nor soluble in water and acids.
Leonardite potassium humate is a mixture of natural organic macromolecular compounds, which is widely present in nature. Because of its unique physiological functions, it has been widely used in agricultural production in recent years.

Under drought conditions, the application of leonardite potassium humate can increase the proline content of plant leaves, promote the water-holding capacity of cells, and increase the activity of plant cell protective enzymes (Nitrate reductase, superoxide dismutase, peroxidase, etc.) and reduce the permeability of cell plasma membranes to comprehensively improve the drought resistance of crops.
Humic acid in leonardite potassium humate can indirectly improve the stress tolerance and resistance of plants by improving the physical and chemical properties of the soil.
In addition, humic acid can also improve its salt resistance by regulating the change of fructose concentration to alleviate the damage of the plasmolemma under salt stress.
Under low temperature stress, humic acid can enhance the activity of polyphenol oxidase by increasing the proline content and abscisic acid content of crops.
And it can weaken the reduction degree of transpiration rate, stomatal conductance and net photosynthetic rate of plants after low temperature stress to improve their cold resistance.
Humic acid also performs well under high temperature stress. The activities of crop superoxide dismutase, peroxidase, etc. are improved, which reduces the rate of superoxide anion production and the content of hydrogen peroxide, and enhances the heat resistance of crops.
Soluble Humic acid in leonardite potassium humate contains a variety of functional groups, which can fix heavy metals on the surface of soil particles through complexation, chelation, and reduction, thereby affecting their migration and reducing the water-soluble state of heavy metals and reducing their toxicity.
At the same time, humic acid can also alleviate the toxic effect of heavy metal cadmium on seedlings. The main mechanism is to inhibit its absorption of cadmium and promote its absorption and accumulation of nutrients such as copper, zinc, iron, and manganese.
Humic acid can promote growth by increasing the sugar content and chlorophyll content of leaves, which indirectly improves the disease resistance of crops.
At the same time, studies have shown that leonardite potassium humate can inhibit the germination of downy mildew sporangia. And compounding with other pesticides can significantly reduce the occurrence of downy mildew. At the same time, humic acids can also enhance the control effect on root knot nematodes.
Humic acid is widely used in pesticide additives due to its special structure and function, and it has also proved that humic acid has a good effect on plant disease resistance.
Our latest organic certificate is SRS,SRS Certification GmbH is a German certification body, whose managers have over 15 years of experience in agricultural research, teaching, organic & good agricultural practices and inspection & certification, in many countries around the globe. We believe in the idea of organic farming, sustainable production, supply chain integrity as means of protecting the environment, producing and supplying healthy food, and generating income for those engaged.
SRS is accredited against ISO/IEC 17065:2012 and currently offers certification according to the SRS Organic Standard, equivalent to Regulation (EC) No 834/2007 and Regulation (EC) No 899/2008; to NOP/USDA - the National Organic Program 7 CFR Part 205 of the United States Department of Agriculture; to Organic JAS (Japanese Agricultural Standard); and to GLOBALG.A.P. standards - in Europe, East and Central Africa and China. Further accreditations and areas of activity are in the pipeline. With representatives in many regions of the world, we also offer supplier audits and input verification.
You can apply humic acid directly into the soil or spray a humic acid solution using a spritzer bottle. Dilute 2 teaspoons of humic acid in every gallon of water or mix about 2 tablespoons of humic acid per cubic foot of potting soil.
Apply humic acid during the spring or fall season, when the plants are actively absorbing nutrients from the soil. You should also use humic acid as a soil amendment when transplanting seedlings.
