[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods of organic fertilizer, what are the advantages of organic fertilizer

Organic fertilizer properties

Organic fertilizer, as an important agricultural resource, has a variety of properties and has a significant impact on crop growth. Organic fertilizer is mainly made of animal and plant residues, livestock and poultry manure and agricultural waste through composting, fermentation and other treatment methods, which is rich in a large amount of organic matter and a variety of nutrients. Compared with chemical fertilizers, organic fertilizers contain higher organic matter and beneficial microorganisms, which can improve soil structure, increase soil fertility, and promote plant root development. The organic matter in the organic fertilizer can improve the water holding capacity and aeration of the soil, and effectively prevent the soil from compacting. Organic fertilizer decomposition is slow, can continue to provide nutrients, to avoid nutrient loss.

Organic fertilizer use

Organic fertilizer is widely used in agricultural production, and its use mainly includes improving soil, providing plant nutrition and improving crop yield. Organic fertilizer can significantly improve the physical and chemical properties of the soil, making the soil more loose and fertile, suitable for crop growth. A large number of organic matter and trace elements in organic fertilizer can meet the various nutritional needs of plant growth and promote the healthy growth of crops. Third, organic fertilizer can enhance the biological activity of the soil, increase the number of beneficial microorganisms in the soil, and form a good soil ecological environment. Organic fertilizer also has certain environmental benefits, which can reduce the use of chemical fertilizers and reduce the pollution of agricultural production to the environment.

Organic fertilizer upstream raw materials

The production of organic fertilizer involves a variety of upstream raw materials, the most important of which are crop residues, livestock and poultry manure and agricultural waste. Crop residues include straw, leaves and fruit residues, which are rich in organic matter and are a good source of organic fertilizer. Livestock manure is another important organic fertilizer raw materials, especially cattle, pigs, chickens and other livestock manure, because it is rich in nitrogen, phosphorus, potassium and other nutrients, widely used in the production of organic fertilizer. Agricultural wastes such as rice husk, peel and branches are also one of the main raw materials of organic fertilizer. After composting and fermentation, these wastes can be converted into high-quality organic fertilizers.

Organic fertilizer downstream application

The downstream application of organic fertilizer is mainly concentrated in the field of agricultural cultivation, including food crops, cash crops, horticultural crops and fruit trees. For food crops, the application of organic fertilizer can significantly improve the yield and quality of crops, and enhance the resistance of plants to diseases and insect pests. For cash crops such as cotton and oil crops, the use of organic fertilizer can not only increase yield, but also improve product quality and increase economic benefits. Horticultural crops and fruit trees also benefit from the application of organic fertilizers, which can promote the development of fruits and improve the sugar content and taste of fruits. Organic fertilizer also occupies an important position in organic agriculture and green agriculture, becoming an important part of environmental protection and sustainable agriculture.

Organic fertilizer production process

The production process of organic fertilizer mainly includes raw material collection, compost fermentation, decomposition treatment and product packaging. Collect all kinds of animal and plant residues, livestock and poultry manure and agricultural waste for classified treatment. Then, these raw materials are mixed in a certain proportion and subjected to compost fermentation. During the fermentation process, it is necessary to turn the pile regularly to ensure the full decomposition of the material and the growth of beneficial microorganisms. After the fermentation, the organic fertilizer reaches a stable state and has a suitable fertilizer effect. The decomposed organic fertilizer is screened and packaged to make commercial organic fertilizer for market sale and use.

Organic fertilizer storage method

The storage method of organic fertilizer has an important influence on its fertilizer efficiency and use effect. Organic fertilizer should be stored in a ventilated and dry place to avoid direct sunlight and rain to prevent nutrient loss and fertilizer deterioration. The site where organic fertilizer is stored should have good moisture-proof facilities to avoid moisture and caking of fertilizer. In order to prevent the decomposition of organic matter and nutrient loss in organic fertilizer, a layer of plastic film or moisture-proof cloth can be covered on the fertilizer. During the storage of organic fertilizer, attention should be paid to fire prevention and insect prevention to avoid the loss of fertilizer caused by high temperature or insect pests. During long-term storage, the quality of the fertilizer should be checked regularly to ensure its stability and fertilizer efficiency.

Organic Fertilizer Market Prospects

With the development of modern agriculture and the enhancement of environmental protection awareness, the market prospect of organic fertilizer is very broad. The rise of organic agriculture and green agriculture has promoted the growth of organic fertilizer demand. Increased consumer demand for organic food has prompted farmers to use more organic fertilizers to produce high quality organic produce. The state attaches great importance to agricultural environmental protection, and has issued a series of policies to support the development of organic fertilizer, which further promotes the development of organic fertilizer industry. As a renewable resource, organic fertilizer conforms to the development concept of circular economy and has broad application prospects. In the future, organic fertilizer will play a more important role in agricultural production and become an important force to promote sustainable agricultural development.

Organic Fertilizer Development Challenges

Although organic fertilizer has many advantages, its development also faces some challenges. The production cost of organic fertilizer is high, the production process is complex, and the output is limited, which is difficult to meet the needs of large-scale agricultural production. The quality of organic fertilizer is uneven, market supervision needs to be strengthened, and consumers' awareness and acceptance of organic fertilizer need to be improved. The application technology and management level of organic fertilizer need to be further improved, and there are still some difficulties in the actual operation of farmers. Therefore, it is necessary to strengthen the research and promotion of organic fertilizer in the future, improve its production technology and quality management level, and promote the wide application of organic fertilizer in agricultural production.

Conclusion

As an important agricultural resource, organic fertilizer has many advantages, such as improving soil, providing nutrition and increasing crop yield. Its upstream raw materials are abundant, downstream applications are extensive, the production process is relatively complex, and the storage method needs to be cautious. Although facing some development challenges, with the development of modern agriculture and the enhancement of environmental protection awareness, the market prospect of organic fertilizer is broad. In the future, by continuously improving the production technology and quality management level of organic fertilizer, organic fertilizer will play a greater role in promoting the development of sustainable agriculture.
