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. However, while the humic acid is from different sources, the performance is very similar. Humus in soils and sediments can be divided into three main parts: humic acid (Humic acid, HA), fulvic acid (fulvic acid, FA) and humin (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.

Working as natural seed germination and room stimulant.Promote germination of seeds and growth of root system.Humic acid stimulates the membrane of seeds to form a strong roots, which is decisive to increase the capacity of root to take up both micro and macro nutrients.
Help to the growth of chlorophyll to promote photosynthesis, thus helping to improve the accumulation of sugar, fat and amino acids in plants, to promote roots and tubers,increase production, improve taste. It can enhance cell growth and help promote photosynthesis, thereby increasing the vitamin content of sugar and fruit crops, meanwhile humic acid can chelate heavy metals in soil to avoid being absorbed by crops, yield and quality will be greatly increased.
