Some people vomited that the organic fertilizer smells heavy and is daunting; some people complain that the organic fertilizer is bulky and the field fertilization takes time and effort; others say that the organic fertilizer has low nutrient content, slow effect, and high yield of crops. In some people's eyes, organic fertilizer seems to be useless, weak to no! The relationship between organic fertilizer and fertilizer: not competition, but cooperation!
Under the objective judgment, is organic fertilizer really a “chicken rib� As we all know, China is one of the four ancient civilizations, with a long history of farming and culture, and has supported tens of thousands of people. The contribution of organic fertilizer is self-evident. . After all, at that time, there was no such thing as chemical fertilizers. The descendants of the Yellow Emperor were not passed down from generation to generation. The organic fertilizer was "useless" and it was not broken!
In fact, the most prominent feature of organic fertilizer is that it can increase and supplement soil organic matter. The organic matter in the soil can significantly improve the physical and chemical properties of the soil, make the soil ploughing better, enhance the water seepage capacity, improve the soil water storage, fertilizer retention, fertilizer supply and drought and flood control capacity, and increase the yield obviously, which is not replaceable by chemical fertilizer.
The author has borrowed a lot of literature from reference and finally discovered this secret. Organic fertilizers, the special contribution to farmland, are mainly in soil and crop.
First, the soil aspect
1. Improve soil fertility and soil fertility
95% trace elements in the soil cannot be directly absorbed and utilized by plants. Organic fertilizers contain a large amount of organic acids, which can quickly dissolve trace elements such as calcium, magnesium, sulfur, copper, zinc, iron, boron, molybdenum and other essential mineral elements into plants that can be directly The nutrients absorbed by the use greatly increase the fertility of the soil.

2. Improve soil quality and promote soil microbial reproduction
Organic fertilizers can multiply microorganisms in the soil, especially many beneficial microorganisms, which can decompose organic matter in the soil, increase the agglomerate structure of the soil, and improve soil composition. The microbial growth rate in the soil is very fast. The activity of microorganisms not only increases the permeability of the soil, but also makes the soil fluffy and soft, the nutrient moisture is not easily lost, the soil water storage and fertilizer capacity is increased, and the soil is avoided and eliminated. The knot.
Second, the crop aspect
1. Provide comprehensive nutrients needed for crops to protect crop roots
The CO2 released by decomposition of organic fertilizer can be used as a material for photosynthesis. Organic fertilizer also contains 5% of nitrogen, phosphorus and potassium, and organic matter is 45%, which provides comprehensive nutrition for crops.
At the same time, it has to be mentioned that the organic fertilizer is decomposed in the soil, and it can be transformed into various humic acids, which are a kind of high molecular substance, which has good complex adsorption performance and has good complex adsorption effect on heavy metal ions. It can effectively reduce the toxicity of heavy metal ions to crops, prevent them from entering the plants, and protect the rhizome of humic acid substances.
2. Enhance the ability of crops to resist disease, drought and sputum
Organic fertilizers contain vitamins, antibiotics, etc., which can enhance crop resistance and reduce or prevent disease. After the organic fertilizer is applied to the soil, it can enhance the water storage and water retention capacity of the soil, and in the case of drought, it can enhance the drought resistance of the crop.
At the same time, organic fertilizer can also make the soil loose, improve the ecological environment of crop roots, promote root growth, enhance root activity, improve crop tolerance, reduce plant mortality, and improve the survival rate of agricultural products.

3. Improve crop yield
Beneficial microorganisms in organic fertilizers use organic matter in the soil to produce secondary metabolites, which contain large amounts of growth-promoting substances. Such as auxin, can promote plant elongation, abscisic acid can promote fruit ripening, gibberellin can promote flowering and fruit setting, increase flowering number, fruit retention rate, increase yield, make fruit full, fresh and tender, can also bring morning market, reach Increase production and income.
4. Improve food safety and greenness
The state has long stipulated that the agricultural production process must limit the excessive use of inorganic fertilizers, and organic fertilizers are the main source of fertilizer for green food production. Since all kinds of nutrients in organic fertilizers are relatively complete, and these substances are completely non-toxic, harmless and non-polluting natural substances, this provides a necessary condition for the production of high-yield, high-quality, non-polluting green food.
The relationship between organic fertilizer and fertilizer: not competition, but cooperation!
Since the advantages of organic fertilizer are so much, do you not need fertilizer? The answer is no. The fertilizer has a quick effect, and it is still very important for the agricultural production to continue to stabilize production and increase production. We must follow the principle of fertilization based on “organic fertilizer and supplemented by chemical fertilizersâ€. Only “organic and inorganic†can achieve long-term stability of agriculture.
According to the survey, the actual utilization rate of chemical fertilizers is only 30% to 45%. When the organic fertilizer is applied, the beneficial soil activity improves the soil structure, increases the soil water retention and fertilizer retention capacity, thereby reducing the loss of nutrients and increasing the effective utilization rate of fertilizers to more than 50%.
