By using organic fertilizer fermentation turners and turners, organic fertilizer can be fully fermented and decomposed. This fully fermented and decomposed organic fertilizer mainly plays the following roles in plant growth:

1. Provide the necessary nutrients for crop growth. Can continuously supply crops for growth. In addition to mineral nutrients, organic matter decomposes in soil to produce carbon dioxide, which can be used as a raw material for crop photosynthesis and is beneficial for improving crop growth. Providing nutrients is the fundamental characteristic and main function of organic fertilizers as fertilizers. Compared with chemical fertilizers, organic fertilizers have the following significant characteristics in terms of nutrient supply.

(1) Rich in nutrients, promoting crop growth.

(2) Nutrient release is uniform and long-lasting, and the nutrients contained in organic fertilizers mostly exist in organic form, which are transformed into dynamic forms that plants can absorb and grow through microbial decomposition.

2. Improve soil structure and enhance soil fertility

(1) Improve soil organic matter content, update soil humus composition, and enhance soil fertility. Soil organic matter is an important indicator of soil fertility and the material basis for forming a good soil environment. Soil organic matter is composed of residual and semi decomposed organic matter and humus in the soil. Organic fertilizers corrode into black or brown organic colloids, namely humus. Humus is a stable organic matter in soil that plays an important role in soil fertility.

(2) Improve the soil. Organic fertilizers form aggregates during the decomposition process, and the density of organic fertilizers is generally lower than that of soil. Applying organic fertilizers to soil can reduce soil bulk density, improve soil aeration, and make the soil better. Organic quality assurance water has strong water retention capacity, high specific heat capacity, low thermal conductivity, dark color, easy heat absorption, and good temperature regulation.

(3) Enhance the soils ability to retain nutrients and water. Organic fertilizers dissociate hydrogen ions in soil solutions, and the water absorption capacity of humus is 400% -600%. Applying organic fertilizers can increase soil water holding capacity, generally by about 10 times. Organic fertilizers have both good water retention and good drainage properties. Therefore, it can alleviate the difference between dry and wet soil, so that the soil environment at the roots of crops does not have too much or too little moisture.

3. Enhance soil biological activity and stimulate plant growth

Organic fertilizers are the main source of energy and nutrients for microorganisms. Applying organic fertilizers is beneficial for soil microbial activity and promotes crop growth and development. Microorganisms not only excrete inorganic nutrients such as nitrogen, phosphorus, and potassium during their activity or after death, but also produce various amino acids such as glutamic acid, proline, vitamins, as well as cytokinins and plant growth hormones, which can have a huge impact on the growth and development of crops.

4. Improve detoxification effect and purify soil environment

Organic fertilizers have detoxifying effects, improve soil self-cleaning ability, and generally reduce lead supply while increasing arsenic fixation.

5. The application of humic organic fertilizers is a diversified process in the production of fermentation machine fertilizers, which produces a bacterial strain that plants can absorb.
