As the saying goes, "every flower of a crop depends on fertilizer". In fact, the fertilizer here is not "fertilizer" but fertilizer (fertilizer is fertilizer, but fertilizer is not necessarily fertilizer). Our ancestors did not use fertilizer and did not have fertilizer. They used organic matter to make various kinds of fertilizer. In the past 40 years, we have abandoned the use of traditional compost and other organic fertilizers in order to increase grain production year by year, and used a large amount of chemical fertilizers. Organic matter such as compost is the food source of soil animals and microorganisms, which leads to the decline of soil carbon content, the lack of organic matter, the imbalance of soil physical structure, the decline of biological diversity, the high availability of nutrients in the soil, the imbalance of mineral elements, and soil hardening. This unsustainable mode of agricultural production has seriously polluted China's limited land and water resources, and ultimately led to a decline in agricultural production, quality decline, and even frequent food safety problems.

The pig dung is soft in nature and has long stamina, which can be used to fertilize seedlings and strengthen seeds. However, if it is used on crops, it should be used after it is decomposed. The purpose and characteristics of the bio-organic fertilizer composter: the products produced by this machine are made from fresh chicken and pig manure, and do not contain any chemical components. However, the digestion ability of chicken and pig is poor, and only 25% of the nutrient components can be consumed, while the other 75% of the nutrient components in the feed are discharged with the manure, so that the dry products contain nitrogen, phosphorus, potassium, organic matter, amino acid, protein and other components. Chicken manure dryer has not only created economic benefits for enterprises, but also made great contributions to human engineering.

We should all know that the organic fertilizer production line is specialized in producing organic fertilizer. Because it is specialized in the treatment of livestock and poultry manure, it effectively reduces the pollution of livestock and poultry manure to the environment, thus achieving the goal. Moreover, the organic fertilizer produced by the organic fertilizer equipment can effectively regulate the soil, improve the quality and solve the problem of soil hardening. Through the organic fertilizer production line equipment, dung can be utilized as resources, which can not only reduce environmental pollution, but also improve the biological safety level of breeding enterprises, reduce the prevalence of livestock and poultry, and produce organic fertilizer, which can improve the quality and safety of agricultural products, generate clean energy, and achieve environmental protection. Let the rural economy embark on the fast track of "safety, environmental protection and green" development.
