Application of humic acid in tomato growth

The current production of tomato quality has generally presented pesticide residues, severe nitrate accumulation, heavy metal pollution, pathogenic microbial contamination, etc. These problems have become a serious obstacle to the development of non-pollution tomato production. Humic acid is a natural polymer organic compound, which has a strong physiological activity to be combined, replaced, complexed, chelated, and other reactions such as heavy metal ions, making it modified to generate a variety of newly beneficial properties. Substances; water-containing hydraulic fertilization fertilizers are a new fertilizer containing humic acid substances and a multi-functional fertilizer. 

The use of humic acid in tomato production will play a positive role in solving the above problems.

Adding humic acid to improve fertilizer utilization：

Tomato is a fertilizer crop. It is necessary to have a large field of large fields, so it has a significant promotion of the fertility, production and quality of tomatoes in a certain range. However, excessive administration not only has a decline in fat, causing economic huge waste, but also destroys soil structures, resulting in soil slabs, environmental pollution. Excessive administration of nitrogen fertilizer has caused the extraordale accumulation of nitrogen in tomato in many regions and severe pollution of groundwater and soil.

Fertilization habits that have low fertilizer utilization, fat effect decline, heavy nitrogen light potassium, heavy inorganic fertilizers have become a major obstacle to restricting non-pollution-free tomato production. Potassium humic acid has both a normal fertilizer's quick-ending effect, and has an organic fertilizer activated soil, sustained release fertilizer, and there is no pollution, no pollution, and the contradiction between the development of agriculture must protect the environment, promoting the ecological benign circulation. Have important significance. Surgery acid acid can increase the utilization of nitrogen fertilizer, especially urea. The effect of humic acid and urea can generate complexes, and the sustained release rate of urea is very obvious, and the nitrogen utilization rate is increased by 6.9% to 11.9%, and it will increase by 15%.

Humic acid can reduce pesticide use, reduce pesticide residues in tomato products：

Humic acid has a good inhibitory effect on certain plant pathogens. Summit acid is more than 85% effect in the prevention and treatment of fuxing, yellowing, frostymidism, and root rot.

Humic acid fulvic acid not only significantly promotes the absorption of nitrogen, phosphorus, and potassium, but also effectively improves the activity of superoxide dismutase SOD and nitrate reductase NR in plants. 

Therefore, humic acid helps to improve tomato itself against anti-aging ability. On the other hand, the sustained release rate of humic acid on pesticides can reduce the use of pesticides.

Humic acid has a improved soil, which is a good soil improvement agent.

Humic acid has activated in many microorganisms and enzymes in the soil. This is due to the high molecular organic compound of humic acid, which provides sufficient carbon, nitrogen element to soil microorganisms, thereby promoting microbial metabolism and growth and development, enhancing microbial activity; while humic acid can also promote soil granules The formation, reducing the soil capacity, improves the cationic exchange, caches the acid and alkalinity, thereby improving soil water storage, insuring, insulation and ventilation ability, ultimately improved the soil structure, fertilizing the land.
