1. Equipment quality problems: organic fertilizer equipment itself has quality problems, which is one of the main reasons for poor use. It may be that the material of the equipment is not corrosion resistant, the structure is unstable, and the manufacturing process is poor, which leads to the frequent replacement of the wearing parts of the equipment and the unstable operation of the organic fertilizer production line, affecting the production efficiency and product quality.

2. The operation technology is not in place: the operator lacks the necessary technical training or insufficient experience, unable to master the operation technology and adjustment methods of the equipment, resulting in the production process can not operate the equipment correctly, adjust the parameters, affecting the maturity and quality of the product.

3. Raw material selection and ratio problem: the quality and ratio of raw materials have a great impact on the quality of organic fertilizer. If the selection of raw materials is improper, the quality is unstable or the proportion is unreasonable, it may lead to the uneven content of organic fertilizer nutrients, slow fermentation speed, and insufficient maturity, which affects the quality and sales effect of the product.

4. Imperfect quality testing and control: Lack of perfect quality testing and control system, unable to carry out comprehensive testing and evaluation of raw materials, intermediate products and final products, resulting in unstable product quality, unable to meet market demand.

5. Poor environmental conditions: the temperature, humidity, ventilation and other conditions of the production environment are poor, which may affect the fermentation effect and product quality. The lack of good production sites, ventilation facilities or pollutant emission control may lead to poor organic fertilizer production results.
