This Humic acid is extracted from high grade leonardite, which can effectively increase the utilization of mineral fertilizers in soil, prevent NPK from leaching or locking up, promote soil structure, increase the capacities of the earth water holding, cation exchange and aeration condition, stimulate activities of soil microorganism, and reduce pollutants in the soil. With the most concentrated humate and highest activity, totally dissolvable in water, it can be easily absorbed by plant, lower the application cost. It is convenient for growers to apply with various methods
