5 major effects of organic fertilizer on soil!

Organic fertilizers are mainly derived from plants or animals and are applied to the soil to provide plant nutrition in the form of carbonaceous matter with the main function. It is processed from biological materials, animal and plant wastes, and plant residues, which eliminates toxic and harmful substances, and is rich in a lot of beneficial substances. Including a variety of organic acids, peptides and rich nutrients including nitrogen, phosphorus, potassium.

What are the benefits of applying organic fertilizers to the soil?

1.Provide comprehensive nutrition. Organic fertilizers are complete fertilizers

It contains nutrients and various beneficial elements required by crops, and the nutrient ratio is comprehensive, which is conducive to crop absorption. Therefore, the more organic fertilizers are applied, the more favorable the balance of soil nutrient ratio, and the more favorable the crops’ absorption and utilization of soil nutrients. More organic fertilizers will not lead to a large increase in soil nutrients, nor will it disrupt the soil nutrient balance.

2.Promote the reproduction of soil microorganisms

Organic fertilizers contain a lot of organic matter and are where various microorganisms grow and multiply. According to the study, after deep ploughing and application of organic fertilizer, soil nitrogen-fixing bacteria almost doubled compared with the control, fiber-decomposing bacteria increased nearly 2 times, and other microbial communities also increased significantly, so the application of organic fertilizer can greatly promote the newly reclaimed land maturation process.

In addition, organic fertilizers can also produce various phenols, vitamins, enzymes, auxins and other substances during the decomposition process, which can promote the growth of crop roots and the absorption of nutrients. Other organic fertilizers have a similar effect.

3.Improve soil fertility and water retention capacity

All organic fertilizers have strong cation replacement ability, which can absorb more nutrients such as potassium, ammonium, magnesium, zinc, etc. to prevent leaching and improve soil fertility retention, especially decomposed organic fertilizers.

In addition, organic fertilizer also has a strong buffer capacity, which can prevent acidity changes and soil compaction caused by long-term application of chemical fertilizers, improve the soil’s own stress resistance, and ensure a good soil ecological environment.

4.Reduce nutrient fixation and improve nutrient utilization

Organic fertilizers contain many organic acids, humic acids, hydroxyls and other substances. They all have strong chelating ability, and can chelate with manganese, aluminum, iron and many other metal elements to form chelate complexes, which can reduce the impact of manganese ions on crops. It can also prevent aluminum and phosphorus from being mixed into closed storage phosphorus that is difficult to be absorbed by crops and becomes ineffective, thereby greatly improving the effectiveness of soil available phosphorus.

5.Accelerate the formation of soil aggregates and improve soil physical and chemical properties

Organic/inorganic aggregates are important indicators of soil fertility. The higher the content, the better the physical properties of the soil, the more fertile the soil, the stronger the soil, water and fertilizer retention capacity, the better the aeration performance, and the better the root growth of crops.
