The organic fertilizer production line not only improves the utilization rate of waste and reduces environmental pollution, but also effectively reduces agricultural production costs, contributing to the development of green agriculture. At the same time, it also provides more organic fertilizer options for farmers, improving the efficiency and quality of agricultural production. The processing of fermented organic fertilizer from cow manure has always been a technically challenging task. So, what are the commonly used methods for processing it? Lets take a look together below.

(1) The method of air drying for cow manure treatment is simple and cost-effective. Suitable for some dry climate areas, its disadvantages are poor performance, easy transmission, and significant weather changes, which can pollute the surrounding air.  

(2) Direct fertilization is popular among farmers due to its simple operation and low cost, but its promotion is limited by factors such as high moisture content and inconvenient use.  

(3) Fermented feces produce biogas through the conversion of organic matter in feces. Biogas can not only be used for power generation, but also replace natural gas, coal, and other substances. Moreover, the residual liquid after biogas production can be used as fertilizer or feed. The prospect of killing two birds with one stone, saving resources and reducing environmental pollution, is very promising.  

(4) In addition, chemical substances such as formaldehyde are used for drying treatment, and the treated feces can be fed to ruminant animals.  

As can be seen from the above, the correct treatment of manure and livestock not only improves resource utilization, but also reduces environmental pollution, which is of great significance for the future development of animal husbandry and ecological environment. So the treatment of livestock and poultry manure is an imperative task.
