What is the specific effect of organic fertilizer on soil fertility?
Organic fertilizer can improve soil physical and chemical properties and improve soil physical and chemical properties. Increasing the application of organic fertilizers, organic fertilizers and chemical fertilizers to continuously increase soil organic matter content is the main link to improve soil fertility. Organic matter can increase soil aeration, water permeability, water storage and improve root growth environment to enhance soil water retention and fertilizer retention.
What elements of organic fertilizer are not provided by chemical fertilizers?
Commercial organic fertilizer provides a large amount of organic nutrients and active substances such as amino acids, DNA, RNA, humic acid, sugars and nucleic acid degradation products for the soil to directly absorb and stimulate root growth. Among them, organic fertilizer contains a large amount of microorganisms to accelerate the decomposition and circulation of organic nutrients in the soil.
What are the specific effects of organic fertilizers to improve product quality?
A large number of chemical fertilizers or improper ratios will lead to a decline in the quality of agricultural products. The combination of organic fertilizers and chemical fertilizers can increase the protein and amino acid content of crops and also increase the content of nitrates in vegetables. An increase in the content of amino acids in plants contributes to the drought resistance of plants and thereby enhances the plant's resistance to stress and pests.
What is the role of organic fertilizers in improving the environment?
The application of organic fertilizer can reduce the amount of fertilizer used and thus reduce the adverse effects of fertilizer on the environment. The production process of organic fertilizer is also a process of solving the resource treatment of urban and rural organic waste and turning waste into treasure. In addition, the application of organic fertilizer can increase the organic matter content and enhance the adsorption of heavy metals and pesticides in the soil to reduce its harm.
What do farmers mainly look for when buying organic fertilizer?
When you look at raw materials, you need to know whether the raw materials used in the products are of High Quality. At present, the organic raw materials used by organic fertilizer manufacturers are soybean meal, sesame meal, sugar residue, cassava residue, bacterial protein, amino acid, humic acid, smoke, etc., and some calcium materials such as bone powder and shell powder are added to increase the calcium content. The fruit tree bitter disease and water heart disease have obvious improvement effects.
Second, see if the ratio of microbial strains is scientific. The enzymes of the excellent strains have higher comprehensive enzyme activity, and the enzymatic activities of the secreted cellulase, xylanase, polygalacturonase, and polygalactose lyase can reach the tolerance of industrial strains. . Through the addition of excellent microbial agents, the maturity cycle can be greatly shortened to improve the decomposing effect.
Third, see if the production line of the factory is strict. The whole production process of commercial organic fertilizer can be summarized as ingredients - decomposed - granulation - cooling - sieving - packaging where the degree of maturity is extremely important. Good product maturity is high and fertilizer lasting; products with insufficient maturity are easy to cause crop burning.
