Increasing the use of organic fertilizer production lines has multiple positive effects on the agricultural environment, as follows:

1. Reduce environmental pollution: Organic fertilizer equipment can efficiently process agricultural waste such as livestock and poultry manure and crop straw, converting them into high-quality organic fertilizers, achieving the resource utilization of waste and reducing the pollution of waste to the environment.

2. Enhance soil quality: Organic fertilizers are rich in organic matter and microorganisms, which can significantly improve soil structure, increase the proportion of soil aggregate structure, and enhance the soil's water and nutrient retention capacity. Long-term application of organic fertilizer can enhance soil fertility, increase the content of soil organic matter and reduce soil acidification.

3. Promote ecological balance and increase soil biodiversity: The microorganisms in organic fertilizers can promote the reproduction of beneficial bacteria in the soil, inhibit the growth of pathogenic bacteria, and reduce the use of pesticides, thereby achieving the green and healthy growth of crops.

4. Enhance the quality of agricultural products: Agricultural products grown with organic fertilizers often have higher nutritional value, better taste and longer shelf life. Reduce the use of chemical fertilizers and pesticides to make agricultural products safer and more reassuring.

5. Promoting sustainable agricultural development: Organic fertilizer production lines convert agricultural waste into fertilizer, reducing the burning or discarding of waste and lowering greenhouse gas emissions.

In conclusion, the application of organic fertilizer production lines not only reduces the pollution of agricultural waste to the environment, but also improves soil quality, promotes ecological balance, enhances the quality of agricultural products, and drives the sustainable development of agriculture.
