When implementing composting, fermentation, and composting methods, the following key technical points should be noted:

Firstly, the selection and mixing of raw materials are crucial. The composition and proportion of different raw materials will directly affect the decomposition efficiency of organic matter and the quality of the product. Therefore, when selecting raw materials, full consideration should be given to their organic matter content, carbon nitrogen ratio, and possible microbial activity.

Secondly, controlling fermentation conditions is also an indispensable part. Whether it is composting, fermentation, or composting, precise control of temperature, humidity, and ventilation conditions is required. These conditions not only affect the reproductive rate of microorganisms, but also directly relate to the degree of organic matter conversion and product stability.

In addition, the selection and use of fermentation agents are also one of the technical points. Adding an appropriate amount of fermenting agent during the fermentation process can significantly promote the proliferation of microorganisms and the conversion of organic matter. However, it should be noted that the selection of fermentation agents should match the characteristics of the raw materials to ensure the fermentation effect.

The post-processing of the product is equally important. After composting and fermentation are completed, the product needs to be processed through processes such as drying, air drying, or granulation to reduce moisture content, improve fertilizer efficiency, and facilitate storage and transportation. At the same time, attention should be paid to preventing secondary contamination and loss of nutrients in the product during the post-processing process.

The first step before starting to produce organic fertilizers is to pre treat the raw materials. This covers multiple stages such as crushing, screening, and removal of impurities and large substances, aiming to ensure the uniformity of materials and lay a solid foundation for subsequent fermentation or composting processes.

Next, whether using composting or fermentation methods, it is necessary to closely monitor the control of fermentation conditions. This includes multiple key factors such as temperature, humidity, and ventilation conditions, which together determine the growth rate of microorganisms and the efficiency of organic matter conversion.

Once the fermentation or composting process is completed, the next step is the subsequent processing. This usually involves processes such as drying, granulation, screening, and packaging, aimed at processing the product into standard granular organic fertilizers.

In summary, the process of producing organic fertilizers involves multiple steps, including raw material pretreatment, fermentation condition control, and subsequent processing. In specific operations, comprehensive consideration should be given to the actual situation and needs to ensure that the quality and fertilizer efficiency of the product meet the expected requirements.
