As a sustainable agricultural production method, organic agriculture has attracted more and more attention worldwide. In this mode of agricultural production, the use of organic fertilizers is a core component, which not only provides the nutrients required by the plants, but also improves the soil structure and enhances the biological activity of the soil. This paper will explore the application of organic fertilizers in organic agriculture and analyze their long-term environmental impact.

1. Definition and function of organic fertilizer

Organic fertilizer is derived from animal and plant residues, domestic waste and other organic matter, after fermentation, decomposition and other treatment made of fertilizer. It is rich in a variety of organic matter and microorganisms, can promote the growth of beneficial microorganisms in the soil, improve the soil's ability to retain water and fertilizer, so as to provide comprehensive nutrition for crops.

2. Application of organic fertilizer in organic agriculture

In organic agriculture, the application of organic fertilizer is mainly reflected in the following aspects:

Improving soil structure: Organic fertilizer can increase the content of organic matter in the soil, improve the soil aggregate structure, and improve the soil ventilation and water permeability.
Provide comprehensive nutrition: organic fertilizer contains a variety of nutrients required for plant growth, such as nitrogen, phosphorus, potassium, etc., to meet the needs of crop growth.
Promote biodiversity: The use of organic fertilizers helps to maintain and increase microbial diversity in soil and promotes the health of soil ecosystems.

3. Organic Fertilizer Production Line and equipment

In the production process of organic fertilizer, the following keywords play a key role:

Organic Fertilizer Production Line




Organic Fertilizer Production Line is a equipment system specially used for the production of organic fertilizer, including raw material treatment, fermentation, drying, screening, packaging and other links. These production lines are able to efficiently convert organic waste into high-quality organic fertilizers.

Fertilizer Granule Compaction Machine



Fertilizer Granule Compaction Machine is one of the key equipment in Organic Fertilizer Production Line. It makes organic fertilizer raw materials into granule form by extrusion, which is easy to apply and store.

Rotary Drum Granulator



Rotary Drum Granulator is another commonly used organic fertilizer granulation equipment. It makes the material form uniform particles by rotating the drum and rolling the material, improving the fertilizer application effect.

Windrow Compost Turning Machine



In the production process of organic fertilizer, it is used to turn Compost materials, promote air circulation, accelerate the decomposition process of compost, and improve compost efficiency.

4. Long-term effects of organic fertilizers on the environment

The use of organic fertilizers has many positive effects on the environment:

Reduce fertilizer use: Organic fertilizers can reduce the reliance on chemical fertilizers and reduce the pollution of fertilizers to soil and water.

Improve soil quality: long-term use of organic fertilizer can increase soil organic matter content, improve soil structure, and enhance soil self-purification ability.

Promote biodiversity: The use of organic fertilizers helps maintain microbial diversity in the soil and promotes the health and stability of ecosystems.

5. Conclusion

The application of organic fertilizers in organic agriculture can not only improve crop yield and quality, but also have a long-term positive impact on the environment. Through the rational design and operation of Organic Fertilizer Production Line and the use of efficient fertilizer granulator equipment, we can make better use of organic waste and achieve sustainable development of agricultural production.
