5 Major Roles of Organic Fertilizer on Soil

1, Provide comprehensive nutrients organic fertilizer is a complete fertilizer containing nutrients and various beneficial elements needed by crops, and the proportion of nutrients is comprehensive and beneficial to crop absorption. Therefore, the more organic fertilizer is applied, the better it is for the balance of soil nutrients, the better it is for crop absorption and utilization of soil nutrients, and it will not cause a large increase of certain nutrients in the soil due to more organic fertilizer, which will destroy the balance of soil nutrients.
2, Promote soil microbial breeding organic fertilizer contains a large amount of organic matter, is a variety of microbial growth and breeding place. According to Huang Jingchun research deep plowing with the application of organic fertilizer, soil nitrogen-fixing bacteria than the control increased by nearly double, fiber-degrading bacteria increased by nearly two times, other microbial communities have also increased significantly, so the application of organic fertilizer can greatly promote the maturation process of newly reclaimed land. In addition, organic fertilizer in the decomposition process can also produce a variety of phenols, vitamins, enzymes, growth factors and other substances, can promote crop root growth and nutrient absorption. Tests have proved that rapeseed cake is particularly effective in the tea garden, not only is the vegetable cake fertilizer rich in nutrients, but more importantly, rapeseed cake in the decomposition process produces a substance that can stimulate root growth, promoting the growth of tea roots and nutrient absorption. Other organic fertilizers also have a similar effect.

3, Improve soil fertilizer and water retention capacity all organic fertilizers have a strong cationic substitution ability, can absorb more potassium, ammonium, magnesium, zinc and other nutrients to prevent leaching, improve soil fertilizer retention capacity, especially well-rotted organic fertilizer fertilizer retention capacity is more obvious. In addition, organic fertilizer also has a strong buffering capacity, can prevent long-term application of chemical fertilizers and acidity changes and soil consolidation, can improve the soil's own resilience, to ensure a good ecological environment of the soil.
4, Reduce nutrient fixation, improve nutrient effectiveness of organic fertilizers contain many organic acids, humic acid, hydroxyl and other substances, they all have a strong chelating ability, can chelate with many metal elements such as manganese, aluminum, iron, etc. to form chelates, can reduce the harm of manganese ions to crops. Can also prevent aluminum and phosphorus combined into a very difficult to be absorbed by the crop of closed state phosphorus and ineffective, greatly improving the effectiveness of the effective state of the soil phosphorus.
5, Accelerate the formation of soil aggregates, improve soil physical and chemical properties of organic - inorganic aggregates is an important indicator of soil fertility, the more it contains, the better the physical properties of the soil, the more fertile the soil, soil retention, water retention, fertilizer capacity, the better aeration performance, the more conducive to crop root growth.
