In agricultural production, nitrogen fertilizers are one of the key factors in promoting crop growth and increasing yields. the sole use of nitrogen fertilizers often leads to issues such as soil salinization and structural damage. the rational application of fermented fertilizers has become a more environmentally friendly and scientific approach to fertilization. Below is a detailed introduction to the combined application methods of nitrogen fertilizers and fermented fertilizers, aiming to provide references for agricultural production.

I. Definition and Functions of Fermented Fertilizers

Fermented fertilizers refer to organic materials decomposed by microorganisms, which produce beneficial microorganisms and release nutrients such as nitrogen. These fertilizers not only improve soil structure but also enhance water retention and fertility preservation capabilities, reduce the use of chemical fertilizers, and support sustainable agricultural development.

II. Selecting Appropriate Types of Fermented Fertilizers

1. Animal-based Fermented Fertilizers: Examples include chicken manure, cow dung, etc. These fertilizers are rich in nitrogen, phosphorus, potassium, and trace elements, effectively promoting plant growth. they must undergo harmless treatment before use to prevent pathogen transmission.
2. Plant-based Fermented Fertilizers: Examples include straw, soybean cake, etc. These fertilizers contain cellulose and hemicellulose, which increase soil organic matter content and improve physical and chemical properties. Careful dosage control is required to avoid compromising soil aeration and moisture retention.
3. Microbial Fermented Fertilizers: Examples include root nodule bacteria and nitrogen-fixing bacteria, which convert atmospheric nitrogen into plant-available forms. These fertilizers are cost-effective and efficient but require proper bacterial strain selection and inoculation.

III. Application Methods for Fermented Fertilizers

1. Base Application: Spread fermented fertilizers evenly on the soil surface and incorporate them into the soil through tillage. Suitable for organic fertilizers, this method directly replenishes soil nutrients and enhances fertility.
2. Topdressing: Apply additional fertilizers during the crop growth period based on nutrient demand. Combining fermented fertilizers with chemical fertilizers improves nutrient utilization efficiency. Ideal for crops with high topdressing requirements, it provides rapid nutrient supplementation.
3. Foliar Spraying: Dilute fermented fertilizers and spray them onto crop leaves to enhance photosynthesis and stress resistance. Suitable for nutrient-demanding crops, this method delivers quick nutritional support.

IV. Precautions

1. Fermentation Process Control: During production, temperature, humidity, and ventilation must be strictly managed to ensure effective fermentation. Over-fermentation may degrade fertilizer quality, while under-fermentation could result in insufficient nutrients.
2. Storage and Transportation: Avoid direct sunlight and high temperatures to maintain microbial activity. Ensure intact packaging to prevent leakage and environmental contamination.
3. Integration with Other Fertilizers: Combine fermented fertilizers with nitrogen, phosphorus, and potassium fertilizers based on crop needs and soil conditions to optimize fertilization outcomes.

combining nitrogen fertilizers with fermented fertilizers offers a scientific and eco-friendly approach. By selecting appropriate types, applying rational methods, and adhering to precautions, the advantages of fermented fertilizers can be maximized, enhancing agricultural efficiency and sustainability. In the future, continued exploration of efficient and environmentally friendly fertilization practices will contribute to agricultural innovation and progress.
