Organic fertilizer equipment plays an important role in promoting agricultural circular economy. The following are its specific mechanisms and practical cases:

1. Waste resource utilization: Organic fertilizer equipment can convert agricultural waste such as livestock and poultry manure and crop straw into high-quality organic fertilizer, realizing the resource utilization of waste.

2. Improve soil fertility: Organic fertilizer produced by organic fertilizer production line can significantly improve soil structure, increase soil organic matter content, and improve soil water and fertilizer retention capacity. This plays an important role in improving soil fertility, promoting crop growth, and improving the quality of agricultural products.

3. Promote the combination of planting and breeding: Organic fertilizer equipment is an important link between planting and breeding. By converting breeding waste into organic fertilizer for planting, a circular agricultural model combining planting and breeding is realized. This model not only improves resource utilization efficiency, but also reduces waste emissions and promotes the virtuous cycle of agricultural ecosystems.

4. Promote green development of agriculture: The application of organic fertilizer equipment has promoted the in-depth implementation of the concept of green development of agriculture. By reducing chemical fertilizer use and optimizing fertilization patterns, organic fertilizers can lower greenhouse gas emissions, reduce agricultural non-point source pollution, and protect the ecological environment.

5. Enhanced Agricultural Ecological Benefits: Under the goal of carbon neutrality, organic fertilizers have become an important means of reducing agricultural emissions. Organic fertilizers are rich in organic carbon, which, when applied to the soil, can increase soil carbon storage and reduce carbon dioxide emissions.
