Humic/Fulvic acid and other humic substances, collectively referred to as humates, are the final stage of organic matter as it degrades to its smallest possible size. They are extremely complex molecules, formed naturally over time by soil microorganisms as they recycle the nutrients and organic matter present in decaying plant material.
In healthy, pristine soils, humates are constantly formed by the life and death cycles of plant roots, microorganisms, and fungi in the soil. Modern agricultural practices have disrupted this cycle - in order to maintain good soil health, it is now necessary to add this critical component back into the soil, so that we can reap the benefits of working with instead of against nature.
A. Improve the structure of soil; increase the buffering power of soil.
In light and sandy soils, humic acid increase the cation exchange capability to retain nutrients and water, importantly to magnify the ability of root to take up nutrients.
In heavy and compact soils, working with fungi to create a crumb structure for better water oxygen and nutrients intake and improved root penetration.
B. Neutralize both acidic and alkaline soil; regulate the pH-value of soil.
Under alkaline conditions, humic acid can buffer the pH and convert the nutrients and trace elements into absorbable form and promote their uptake by the roots, as under high pH value many essential nutrients and trace elements are not in plant-available form.
In acidic soil, it can largely reduce the toxins such as the ally aluminum and heavy metals, which will be bonded firmly and immobilized by humic acid, thus their toxicity is reduced and phosphate is bonded by aluminum is released.
Salinization of soil: Salts are split up by the high cation exchange capability cation (eg.Ca+, Mg+) are bonded and chelated. The high osmotic pressure within the root area is largely reduced.
C. Stimulate plant growth, increase the yield and quality.
Stimulate the membrane of seeds as well as the metabolic activities and thereby increase the germination rate. Increase the capacity of root to take up nutrients (N, P, K + Fe, Zn and other trace elements) as these elements is easier to be converted into forms available to plants. Accordingly, the yield will be increased up to 30%. Enhanced cell assimilation as well as photosynthesis increase the plant's sugar and vitamin content.
D. Reduce nitrate leaking into the groundwater and protect the underground water.
Humic acid binds the nitrate and keep it around the root zone, in this way drinking water is better preserved.
E. Increase the effectiveness of herbicide pesticide and fungicide, immobilize or reduce their harmful residues.
