To make the soil suitable for the growth of crop roots, it is necessary to improve the physical properties of the soil. Increase the organic matter content of the soil, make the soil aggregate structure more, and less harmful elements in the soil.
Organic fertilizer is made of livestock and poultry manure and plant residues. After high-temperature fermentation, the toxic and harmful substances are eliminated. It is rich in a large amount of organic substances, including: a variety of organic acids, peptides, and nitrogen, phosphorus, Rich nutrients including potassium. It is a green fertilizer that is beneficial to crops and soil。
Organic fertilizer refers to a type of fertilizer that is rich in organic matter and can not only provide a variety of inorganic and organic nutrients to crops, but also improve soil fertility.
Features of organic fertilizer:
1. Comprehensive nutrients, slow-release and long-lasting, soft, lasting and stable fertility;
2. It has the activity of activating soil enzymes, promoting root development, and enhancing photosynthesis;
3. Reduce the nitrate content of the product, improve the quality of the crop and increase the yield; the product is bright in color, large and sweet;
4. If applied continuously, it can significantly increase the content of soil organic matter, improve soil aeration, water permeability, and fertility retention, so as to improve soil fertility and reduce environmental pollution caused by chemical fertilizers.
Benefits of organic fertilizer:
1. There are a large number of beneficial microorganisms in the organic fertilizer, which can decompose the organic matter in the soil, increase the soil aggregate structure and improve the soil composition. Increase the air permeability of the soil, but also make the soil fluffy and soft, the nutrient water is not easy to lose, increase the soil water and fertilizer storage capacity, avoid and eliminate soil compaction.
2. The beneficial microorganisms in organic fertilizer can also inhibit the reproduction of harmful bacteria, can effectively inhibit soil harmful organisms, save labor and money, and have no pollution.
3. 95% of the trace elements in the soil are in insoluble form and cannot be absorbed and utilized by plants. Microbial metabolites contain a large amount of organic acids, which are like hot water added to ice cubes. It can dissolve the trace elements calcium, magnesium, sulfur, copper, zinc, iron, boron, molybdenum and other essential mineral elements of plants, and turn them into nutrient elements that can be directly absorbed and utilized by plants, greatly increasing the soil’s fertility supply capacity.
4. The beneficial microorganisms such as Bacillus subtilis in the organic fertilizer use the organic matter in the soil to produce secondary metabolites, which contain a lot of growth-promoting substances. For example, auxin can promote plant elongation and growth, abscisic acid can promote fruit maturity, gibberellin can promote flowering and fruit setting, increase the number of flowering, fruit retention, increase yield, make the fruit plump, fresh and tender, and can be marketed early. Achieve increased production and income.
5. The microorganisms in organic fertilizers have strong vitality and survive in the soil for a long time. Nitrogen-fixing bacteria, phosphorus-dissolving bacteria, potassium-dissolving bacteria and other microorganisms can use nitrogen in the air and release potassium and phosphorus in the soil that are not easily absorbed by crops. Continuously supply crop nutrients. Therefore, organic fertilizer also has long-term effects.
6. According to relevant data, it is confirmed that the utilization rate of chemical fertilizers in our actual production is only 30%-45%. Most of them cannot be directly absorbed and utilized by plants, resulting in undesirable consequences such as soil salinization and compaction. When we apply organic fertilizer, its beneficial biological activities can improve the soil structure, increase the soil’s ability to retain water and fertilizer, thereby reducing the loss of nutrients. Coupled with the effect of organic matter beneficial microorganisms to dissolve phosphorus and potassium, the effective utilization rate of chemical fertilizers can be increased to more than 50%.
7. Organic fertilizer can increase crop yield and improve the quality of agricultural products. Under the same nutrient elements, organic fertilizer is compared with chemical fertilizer. When applied as base fertilizer, organic fertilizer is generally better than chemical fertilizer. When applied as topdressing, it has been fully decomposed. The effects of organic fertilizers are often better than chemical fertilizers. Especially improving the quality of agricultural products is more beneficial than chemical fertilizers.
8. Organic fertilizer can promote the growth of soil microorganisms and promote the absorption and utilization of crops. Organic fertilizer contains a large amount of organic matter and is the best place for the growth and reproduction of various microorganisms. The organic matter of organic fertilizer can also produce various phenols, vitamins, enzymes, auxins and hormone-like substances in the process of decomposing, which can promote the growth of crop roots and the absorption of nutrients.
9. Reduce nutrient fixation and improve nutrient effectiveness. Organic fertilizer contains many organic acids, humic acids and other hydroxyl substances. They all have strong chelating ability and can chelate with many metal elements to form chelate. Prevent the soil from fixing these nutrients and failing. For example, organic fertilizers and phosphate fertilizers are used in combination. The organic acids and other chelates in the organic fertilizers can chelate the highly active aluminum ions in the soil, which can prevent the combination of aluminum and phosphorus to form closed storage phosphorus that is difficult for crops to absorb. Increase soil available phosphorus content.
10. Accelerate the formation of soil aggregates and improve soil physical and chemical properties. Organic-inorganic aggregates are an important indicator of soil fertility. The more its content, the better the physical properties of the soil. The more fertile the soil, the stronger the ability to preserve soil, water and fertilizer. , The better the aeration performance, the more conducive to the growth of crop roots.
