Poultry and livestock manure is a common organic waste in rural areas and breeding farms, which contains a large amount of nutrients and microorganisms, but also has problems such as odor and pathogenic bacteria. Aerobic fermentation refers to the decomposition process of organic matter in the presence of sufficient oxygen, which refers to the process in which microorganisms use organic matter and its metabolites for energy and substance conversion. Aerobic fermentation of poultry and livestock manure can bring the following benefits:

1. Reduce odor and pollution

Poultry and livestock manure contains a large amount of volatile gases, such as ammonia, hydrogen sulfide, etc. These gases can produce unpleasant odors and pose a threat to human and animal health. Through aerobic fermentation, it can promote the decomposition and transformation of organic waste, reduce the emission of volatile gases, reduce the generation of odors, and effectively reduce environmental pollution.

2. Improving fertilizer quality and nutritional value

After aerobic fermentation, the organic components of poultry and livestock manure are decomposed and transformed, forming more stable organic fertilizers and removing some plant toxins and pathogens. In addition, aerobic fermentation can release a large amount of heat energy, increase the temperature and humidity of organic matter, promote microbial metabolism and reproduction, and improve the nutritional value and utilization efficiency of fertilizers.

3. Reduce production costs

Aerobic fermentation has low construction costs, high safety performance, and can reduce production costs for farmers and farms.

4. Protecting soil and environment

After aerobic fermentation, poultry and livestock manure has high fertility and can replace chemical fertilizers, playing a positive role in soil improvement and protection. Meanwhile, aerobic fermentation can also reduce non-point source pollution and greenhouse gas emissions, reduce the burden on the environment, and mitigate the impact on climate change.

In short, aerobic fermentation of poultry and livestock manure is an environmentally friendly, efficient, and economical treatment method. It can not only reduce odor and pollution, improve fertilizer quality and nutritional value, reduce production costs and protect soil, but also promote sustainable development of agriculture and ecological civilization construction.
