Ten functions of bio-organic fertilizer

The organic matter in the soil can significantly improve the physical and chemical properties of the soil, improve soil cultivability, increase water seepage ability, improve soil water storage, fertilizer retention, fertilizer supply and drought and flood prevention capabilities, and increase production. This is not a substitute for chemical fertilizers. Increase The main method of soil organic matter is to increase the application of organic fertilizer. At present, the country vigorously advocates the application of organic fertilizer and biological organic fertilizer.

The specific role of organic fertilizer

1.There are a large number of beneficial microorganisms in bio-organic fertilizer, which can decompose the organic matter in the soil, increase the soil aggregate structure, and improve the soil composition. Microorganisms multiply very fast in the soil. They are like a big invisible net, intricately intricate. After the death of the microbial cells, many fine pipes are left in the soil. These fine pipes not only increase the air permeability of the soil, but also make the soil fluffy and soft, and the nutrients and water are not easily lost, which increases the soil storage. Water storage capacity to avoid and eliminate soil compaction.

2.The beneficial microorganisms in bio-organic fertilizer can also inhibit the reproduction of harmful bacteria, so that we can use less pesticides. If applied for many years, it can effectively inhibit soil harmful organisms, saving labor, money, and 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. These substances are like hot water added to ice. Trace elements Calcium, magnesium, sulfur, copper, zinc, iron, boron, molybdenum and other essential mineral elements for plants dissolve and become nutrient elements that can be directly absorbed and utilized by plants, greatly increasing the fertility supply capacity of the soil.

4.The beneficial microorganisms such as Bacillus subtilis in the bio-organic fertilizer use the organic matter in the soil to produce secondary metabolites, which contain a large amount of growth-promoting substances. For example, auxin can promote plant elongation and growth, abscisic acid, can fully mature fruit, gibberellin can promote flowering and fruiting, increase the number of flowering, fruit retention, increase yield, make the fruit plump, fresh and tender, and can be marketed early , To increase 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, the utilization rate of chemical fertilizers in our actual production 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, which cannot be directly absorbed and used by plants, and it will also cause soil salinization and compaction and other undesirable consequences. 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 fertilizers can be increased by more than 50%.

7.Organic fertilizers can increase crop yields and improve the quality of agricultural products. Under the same nutrient elements, organic fertilizers are compared with chemical fertilizers. When applied as base fertilizers, organic fertilizers generally have better effects than chemical fertilizers. Decomposed organic fertilizers are often better than chemical fertilizers. Especially improving the quality of agricultural products is more beneficial than chemical fertilizers. Many countries are developing “ecological agriculture” and “organic agriculture”, which attach great importance to the use of organic fertilizers and stipulate organic fertilizers as the main source of fertilizer for the production of green food.

8.Organic fertilizer can promote the growth of soil microorganisms and promote the absorption and utilization of crops. Organic fertilizer contains a lot 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 the effectiveness of nutrients. Organic fertilizers contain many organic acids, humic acids and other hydroxyl substances. They all have strong chelating ability and can chelate with many metal elements to form chelating compounds, which can prevent the soil from fixing these nutrients and failing. For example, organic fertilizer and phosphate fertilizer are used in combination. The organic acid and other chelating compounds in the organic fertilizer 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 soil, water, and fertilizer retention capabilities, the better the aeration performance, and the better it is for the growth of crop roots.
