Ten functions of organic fertilizer you need to know
Date:2019/10/30
With the continuous development of agriculture, organic fertilizer has more and more influence on agriculture. At the same time, it also plays an important role in the protection and improvement of soil environment. Let's summarize the functions 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 and increase the aggregate structure of the soil. The propagation speed of microorganisms in the soil is very fast, which not only increases the permeability of the soil, but also makes the soil become fluffy and soft, increases the capacity of soil water and fertilizer storage, and avoids and eliminates the hardening of the soil.
2. Beneficial microorganisms can also inhibit the propagation of harmful bacteria, so that we can use less pesticides. If applied for many years, it can effectively inhibit soil pests, save labor, money and no pollution.
3. 95% of the microelements in the soil are in the form of insoluble, which can not be absorbed and utilized by plants. However, the metabolites of microorganisms contain a large number of organic acids, which can dissolve the essential mineral elements such as calcium, magnesium, sulfur, copper, zinc, iron, boron, molybdenum, etc., and become the nutrient elements that can be directly absorbed and utilized by plants, which greatly increases the fertilizer supply capacity of the soil. 。
4. Bacillus subtilis and other beneficial microorganisms in the bio organic fertilizer utilize the organic matter in the soil to produce secondary metabolites, which contain a large number of growth promoting substances. For example, auxin can promote plant elongation and growth, abscisic acid, fruit ripening, gibberellin can promote flowering and fruit setting, increase the number of flowers and the rate of fruit preservation, increase the yield, make the fruit plump, bright and tender, and put it on the market early, so as to increase production and income.
5. The microorganism in organic fertilizer has strong vitality and can survive in the soil for a long time. Nitrogen fixing bacteria, phosphorus dissolving bacteria, potassium dissolving bacteria and other microorganisms can use the nitrogen in the air and release the potassium and phosphorus in the soil that are not easy to be absorbed by the crops to continuously supply the crops with nutrients. So organic fertilizer has long-term effect.
7. Organic fertilizer can increase crop yield and improve the quality of agricultural products. Compared with chemical fertilizer, the effect of organic fertilizer is better than that of chemical fertilizer. Especially in improving the quality ratio of agricultural products. The United States, Western Europe, Japan and other developed countries are springing up "ecological agriculture" and "organic agriculture". They attach great importance to the use of organic fertilizer, and set organic fertilizer as the main source of green food production.
8. Organic fertilizer can promote the growth of soil microorganisms and the absorption and utilization of crops. It is the best place for the growth and reproduction of various microorganisms. Organic matter can also produce a variety of phenols, vitamins, enzymes, auxin and hormone like substances in the organic fertilizer production process, so as to promote the growth of crop roots and the absorption of nutrients.
9. Reduce nutrient fixation and improve nutrient availability. Organic fertilizer contains a lot of organic acids, humic acids and other hydroxy substances, which have strong mixing ability and can mix with many metal elements to form a mixture, which can prevent the soil from fixing and invalidating these nutrient elements.
10. Accelerate the formation of soil aggregate and improve the physical and chemical properties of soil. Organic-inorganic aggregate is an important index of soil fertility. The more it contains, the better the physical properties of the soil. The more fertile the soil is, the stronger the ability of soil, water and fertilizer conservation is, the better the ventilation performance is, and the more conducive to the growth of crop root system.
