Organic fertilizer has many functions. It can improve the soil environment, promote the growth of beneficial microorganisms, increase fertilizer utilization efficiency, reduce the use of chemical fertilizers, improve the quality and quality of agricultural products, and promote the healthy growth of crops.

Organic fertilizer fermentation mainly goes through three stages

The first stage is the heating stage, which mainly involves the decomposition of some of the main raw materials, such as molds, spore forming bacteria, etc., into sugars under aerobic and low-temperature conditions. During this process, a large amount of heat is generated, and the temperature can rise to over 40 degrees Celsius.

The second stage is included in the high temperature stage. As the temperature rises, thermophilic microorganisms begin to become active. They decompose complex organic compounds such as cellulose and continue to generate heat until 70-80 degrees Celsius. At this point, microorganisms including thermophilic microorganisms begin to die or enter dormancy. If the sealing is not good, the temperature may not be sufficient to fully decompose.

The third stage is the cooling phase, during which the organic matter has basically decomposed. When the temperature drops below 40 degrees, the microorganisms involved in the first process become active again. If the cooling is too fast, it indicates that the decomposition is not enough and can be re stacked for a second heating.
