Do you know that organic fertilizer has a profound impact on soil improvement. It can significantly improve the physical and chemical properties of the soil, making it more suitable for farming and enhancing its water infiltration capacity. One of the key measures to increase soil organic matter is to increase the application of organic fertilizer. Next, we will explore the eight significant effects of organic fertilizer.
a. Basic effects
Biological organic fertilizer is rich in a large number of beneficial microorganisms, which can decompose organic matter in the soil, thereby increasing the soil’s aggregate structure and improving the composition of the soil. These microorganisms multiply rapidly in the soil to form a huge network, which not only increases the permeability of the soil, but also makes the soil fluffy and soft.
In addition, the organic acids contained in the metabolites of microorganisms can dissolve trace elements in the soil, such as calcium, magnesium, sulfur, copper, zinc, iron, boron, molybdenum, etc., thereby improving the soil’s fertilizer supply capacity.
b. Increase yield and quality
These beneficial microorganisms can also effectively inhibit harmful pathogens in the soil and reduce the use of pesticides. Long-term and continuous application of organic fertilizer can significantly inhibit harmful organisms in the soil, achieving labor-saving, money-saving and pollution-free agricultural production.
c. Long-term efficacy of microorganisms
Microorganisms such as Bacillus subtilis in biological organic fertilizer can use organic matter in the soil to produce secondary metabolites, including a variety of growth-promoting substances. These substances can promote plant elongation growth, fruit ripening, flowering and fruit setting, thereby improving yield and quality.
d. Improve the utilization rate of chemical fertilizers
Relevant data confirm that the application of organic fertilizers can significantly improve the effective utilization rate of chemical fertilizers. Due to the addition of organic fertilizers, the soil structure is improved, the water and fertilizer retention capacity is increased, and the loss of nutrients is reduced. At the same time, the phosphorus and potassium dissolving effect of microorganisms can further improve the utilization rate of chemical fertilizers.
e. Comparison of advantages of chemical fertilizers
Compared with chemical fertilizers, under the same nutrient element conditions, organic fertilizers are more effective when used as base fertilizers or topdressing. Especially in terms of improving the quality of agricultural products, the advantages of organic fertilizers are more obvious. Many developed countries such as the United States, Western Europe, and Japan attach great importance to the use of organic fertilizers.
f. Promote plant nutrient absorption
Organic fertilizer can promote the growth of soil microorganisms and the absorption of nutrients by crops. The organic matter in organic fertilizer provides a good growth environment for microorganisms, and the substances produced during its decomposition process can also promote the growth of crop roots and the absorption of nutrients.
g. Improve nutrient effectiveness
Organic fertilizer can also reduce nutrient fixation and improve nutrient effectiveness. The organic acids, humic acids and other substances have strong chelating ability and can form chelates with many metal elements, thereby preventing the soil from fixing these nutrients ineffectively. For example, when mixed with phosphate fertilizer, the chelates in organic fertilizer can prevent aluminum from combining with phosphorus to form insoluble phosphorus, thereby increasing the content of effective phosphorus in the soil.
h. Improve soil aggregates
In addition, organic fertilizer can accelerate the formation of soil aggregates and further improve the physical and chemical properties of the soil. Aggregates are an important indicator for measuring the fertility of soil. The higher the content, the better the physical properties of the soil, and the stronger the ability to retain soil, water and fertilizer, the more conducive to the growth of crop roots.
At the same time, organic fertilizer can enhance the soil’s ability to store water, retain fertilizer, supply fertilizer, and resist drought and flood, thereby significantly increasing crop yields, which is unmatched by the use of chemical fertilizers alone.
