Why use organic fertilizer?

Organic fertilizer raw materials contain a variety of nutrients, rich in organic matter, can strengthen the activities of microorganisms, fertilizer effect is lasting, not only can supply the needs of crop nutrition, but also can improve the soil water, heat and ventilation conditions, enhance soil ripening.
The method to improve the soil structure is mainly to increase the soil organic matter and increase the application of organic fertilizers, including human and animal manure, soil and miscellaneous fertilizers, straws, and commercial organic fertilizers.

How does organic fertilizer improve soil structure?

1. Improve the fertility of the soil

95% of the trace elements in the soil exist in the form of insoluble, can not be absorbed by plants, and microbial metabolites contain a large number of organic acids. These substances are like hot water added to ice, which can be quickly Dissolving trace elements such as calcium, magnesium, sulfur, copper, zinc, iron, boron, molybdenum, and other essential mineral elements for plants, turning them into nutrient elements that can be directly absorbed and utilized by plants, greatly increasing the soil’s fertility supply capacity.
The organic matter in the organic fertilizer increases the organic matter content in the soil, which reduces the soil cohesiveness, and the sandy soil has stronger water and fertilizer retention performance so that the soil forms a stable aggregate structure, which can exert a good fertility coordination supply capacity. After using organic fertilizers, the soil will become loose and fertile.

2. Promote the reproduction of soil microorganisms

Organic fertilizer can multiply soil microorganisms, especially many beneficial microorganisms, such as nitrogen-fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, and so on. These beneficial microorganisms can decompose the organic matter in the soil, increase the soil aggregate structure, and improve the soil composition.

Microorganisms in the soil reproduction rate are very fast, they are like a largely invisible net, intricate. After the microorganisms die, they leave a lot of fine pipes in the soil. These fine pipes not only increase the permeability of the soil, but also make the soil fluffy and soft so that the nutrient and water are not easy to lose, increase the capacity of soil water storage and fertilizer storage, and avoid and eliminate the soil hardening.

The beneficial microorganisms in organic fertilizer can also inhibit the reproduction of harmful bacteria, so you can do less medicine, if applied for many years, can effectively inhibit soil harmful organisms, save labor, save money, no pollution.

At the same time, organic fertilizer contains a variety of active enzymes secreted by the digestive tract of animals, as well as a variety of enzymes produced by microorganisms. When these substances are applied to the soil, the enzyme activity of the soil can be greatly improved. Long-term use of organic fertilizer can improve soil quality. Fundamentally improve soil quality.

3. Provide comprehensive nutrition needed by crops

Organic fertilizers contain a large number of nutrients, trace elements, sugars, and fats needed by plants.
The CO2 released from the decomposition of organic manure can be used as a material for photosynthesis. Organic fertilizer also contains 5% of nitrogen, phosphorus, and potassium, and 45% of organic matter, which can provide comprehensive nutrition for crops.

At the same time, it must be mentioned that the organic fertilizer is decomposed in the soil and can be transformed into various humic acids. It is a kind of high molecular substance, has good complex adsorption performance, and has a good complex adsorption effect on heavy metal ions. , Can effectively reduce the poisoning of heavy metal ions to crops, prevent them from entering the plants, and protect the rhizomes of humic acid substances.

4. Enhance crop resistance to disease, drought, and flood tolerance

Organic fertilizer contains vitamins, antibiotics, etc., which can enhance the resistance of crops and reduce or prevent the occurrence of diseases. After the organic fertilizer is applied to the soil, it can enhance the water storage capacity of the soil, and in the case of drought, it can enhance the drought resistance of crops.
At the same time, organic fertilizer can also loosen the soil, improve the ecological environment of crop roots, promote root growth, enhance root vitality, improve crop tolerance to waterlogging, reduce plant mortality, and increase the survival rate of agricultural products.

5. Improve food safety and greenness

Organic fertilizer is the main source of fertilizer for the production of green food. Since the various nutrient elements in organic fertilizers are relatively complete, and these substances are completely non-toxic, harmless, and non-polluting natural substances, this provides the necessary conditions for the production of high-yield, high-quality, and pollution-free green food. The aforementioned humic acid substances can reduce the harm of heavy metal ions to plants, which is equivalent to reducing the harm of heavy metals to the human body.

6. Increase crop yield

The beneficial microorganisms in organic fertilizers utilize the organic matter in the soil to produce secondary metabolites, which contain a large number of growth-promoting substances. If auxin, can promote plant elongation growth, abscisic acid can promote fruit ripening, gibberellin can promote flowering and fruit setting, increase the number of flowering, fruit retention rate, improve output, make the fruit full, fresh and tender color, but also early listing, to increase production and increase revenue.

7. Reduce nutrient loss

The actual utilization rate of chemical fertilizers is only 30%-45%. Part of the lost chemical fertilizer is decomposed and released into the atmosphere, part is lost with soil and water, and part is fixed in the soil and cannot be directly absorbed and used by plants.

When organic fertilizer is applied, beneficial biological activities improve the soil structure and increase the soil’s ability to retain water and fertilizer, thereby reducing the loss of nutrients. Coupled with the effect of the beneficial microorganisms to dissolve phosphorus and potassium, the effective utilization rate of chemical fertilizers can be increased to more than 50%.
