HUMIC ACID is an organic acid derived from decayed organic matter. It is the most important components of Potassium Humates. QFG humic acid and potassium humate is extracted from high grade leonardite, which has been oxidized by nature, resulting in a highly active and concentrated humic acid, providing numerous benefits to crop production. It helps break up clay and compacted soils, assists in transferring micronutrients from the soil to the plant, enhances water retention, and stimulates development of microflora populations in soils. With different levels of water solubility, humic acid products can be applied by various methods.
(1) Promote effective utilization of fertilizers in soil. It also can promote the absorption of N, P, K and trace element in plants.
(2) Improve soil structure, improve water storage capacity, anti-hard-water ability and air permeability of soil, increase the amount of organic matters in soil.
(3) Stimulate activities of soil microorganism, reduce pollutants in the soil, adjust the PH value of soil and decrease the damages caused by acid or alkaline.
