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.

Benefits of Humic Acids in agriculture:

l         Increased resistance to fungal attacks.

l         Increase the utilization of chemical fertilizers.

l         Improve soil structure; increase the capacities of the earth water holding, cation exchange and aeration condition.

l         Stimulate activities of soil microorganism.

l         Scavenge heavy metals in soil.
