Humic acid

(1) the role of soil modification

Because it contains a large amount of organic matter and organic colloids, so it can be dispersed without structure of the soil particles junction together, the formation of water is not easy to disperse water-stable particles, thereby increasing the soil void, easy to fall, improve the aeration and permeability of the soil, strengthen the ability to retain soil, tillage becomes better.

(2) Nutritional effect

Humic acid has a strong adsorption capacity, which can activate the mineral elements in the soil and improve its effectiveness. In addition, it can also stimulate the development of the root system, thereby enhancing the root system of insoluble nutrients, such as phosphorus and some trace elements absorption and utilization, in addition to making chemical fertilizers fertilizer effect fast, can be timely for crop use.

(3) stimulating effect

It is mainly manifested in the ability to promote seed germination, improve seedling emergence rate, promote root growth, improve the ability of crops to absorb water and nutrients, increase branching and early maturity.

Humic acid 30% - 80%, micro-silica powder 20% - 70%. Humic acid is made by mixing differentiated coal or lignite (92%-93%) with ammonium carbonate (7%-8%), and carrying out 7-10 days of ammoniation with water to decompose a large amount of humic acid and part of organic matter.
