What kind of fertilizer is humus fertilizer?

Humic fertilizer is what we often see now. It is an amorphous polymer organic weak acid mixture of animal and plant residues, mainly plant residues, which are decomposed and transformed by microorganisms during metabolism and accumulated through a series of physical and chemical reactions. This is a new type of fertilizer.

First, the main role of humic acid fertilizer

1, soil improvement

Humic acid is a porous substance, which can improve the aggregate structure of soil and play an important role in maintaining soil water and fertilizer, regulating air permeability and balancing pH value. Adsorption and complexation of humic acid can reduce pesticide residues, heavy metals and other harmful substances in soil. At the same time, humic acid has colloidal properties and can promote the growth and reproduction of beneficial bacteria.

2. Promote crop growth

The active factors contained in humic acid can enhance the activities of various enzymes in crops, thus promoting the growth and development of crops, such as improving the early germination of seeds and the high emergence rate, making crops have developed roots, strong plants, enhancing photosynthesis and accelerating the transformation and absorption of nutrients.

3. Improve fertilizer utilization rate

The active factors in humic acid have strong exchange and adsorption capacity, which can greatly improve the utilization rate of fertilizer. It can improve the utilization ratio of nitrogen fertilizer 10% and phosphorus fertilizer 10 ~ 30%. In addition, it can also reduce the loss of potash fertilizer. So humic acid is often used as fertilizer synergist.

4. Improve the effectiveness of pesticides.

Pest control: Humic acid has a good preventive effect on some diseases of crops, such as Fusarium wilt, verticillium wilt, downy mildew, root rot and so on. Applying humic acid fertilizer to soil has an ideal effect on preventing and controlling the above diseases. Reduce the use of pesticides: mixing with pesticides can reduce the decomposition rate of organophosphorus in pesticides. In addition, the strong internal surface area of humic acid has a strong adsorption capacity, thus playing a slow-release role in pesticides. Can reduce the use of pesticides? Even about half. 5. It can enhance the stress resistance of crops.

Humic acid can promote crop drought and cold resistance; It can inhibit the growth of many harmful bacteria, thus reducing the occurrence of soil-borne diseases.

6. It can improve the quality of agricultural products.

Humic acid can promote the synthesis, transformation and accumulation of various enzymes and sugars in crops, thus improving the taste and quality of agricultural products. Using humic acid fertilizer in vegetable planting and tobacco planting will have a good effect.

Second, the types of humic acid fertilizer

At present, there are two kinds of humic acid fertilizers on the market: solid and liquid.

Third, the application method of humic acid fertilizer

1, application method of solid humic acid fertilizer

It can be used as base fertilizer and topdressing: the effect of base fertilizer is greater than topdressing, the effect of concentrated application (point application and strip application) is greater than that of spreading application, and the effect of deep application is stronger than that of shallow application. The depth of fertilization is generally recommended to be about 12 cm from the seed. Seed fertilizer: Humic acid fertilizer as seed fertilizer is safer and more efficient than chemical fertilizer. 2. Application method of liquid humic acid fertilizer

Liquid humic acid fertilizer can be used for seed soaking, root soaking, spraying and topdressing.

Summary: Humic acid fertilizer has a good effect in improving soil, improving fertilizer utilization rate, improving crop stress resistance and improving agricultural product quality, and is increasingly welcomed by farmers. Because it is a new type of fertilizer, it is also easy to be deceived, so try to choose humic acid fertilizer produced by reliable production enterprises when purchasing and using it.
