As an emerging environmental protection technology, organic fertilizer production lines can not only convert waste such as crop straw and livestock manure into high-quality organic fertilizers, but also effectively reduce environmental pollution in agricultural production processes. The following are several highlights of organic fertilizer production lines in terms of environmental protection and income increase:

1. Improving soil fertility: Organic fertilizers produced by organic fertilizer production lines contain rich elements such as nitrogen, phosphorus, and potassium, which can improve soil structure, enhance soil fertility, reduce fertilizer use, and lower agricultural production costs.

2. Promote crop growth: Microorganisms in organic fertilizers can effectively decompose harmful substances in the soil, improve crop disease resistance, promote crop growth, and increase yield.

3. Improving the ecological environment: The application of organic fertilizer production lines helps to reduce environmental pollution caused by fertilizers, pesticides, etc., reduce agricultural non-point source pollution, and protect the ecological environment.

4. Increase farmers income: Organic fertilizers produced by organic fertilizer production lines can be used for crops grown by oneself or sold to other farmers, increasing farmers income.

5. Achieving resource recycling: The organic fertilizer production line converts waste into organic fertilizer, achieving resource recycling and reducing environmental pollution.
