Functional nitrogen fertilizers are a category of nitrogen-based fertilizers with specialized properties. They typically contain specific nutrients and bioactive substances that promote crop growth, increase yields, and improve quality. The application methods for functional nitrogen fertilizers differ from conventional nitrogen fertilizers. Below are some common usage approaches:

1. Basal Application Method: Spread the functional nitrogen fertilizer evenly on the soil surface before sowing or transplanting, then plow the soil to fully integrate the fertilizer. Suitable for large-scale planting, this method ensures uniform distribution of nutrients.

2. Ditch Application Method: Open ditches between crop rows or plants, apply the fertilizer into the ditches, and cover with soil. Ideal for small-scale planting, this reduces direct soil contact and minimizes nutrient loss.

3. Hole Application Method: Dig holes near the crop roots, apply the fertilizer, and cover with soil. Best for shallow-rooted crops, this method minimizes potential root damage.

4. Foliar Spraying Method: Dissolve the functional nitrogen fertilizer in water and spray it onto crop leaves using a sprayer. Suitable for crops requiring rapid nitrogen supplementation, such as fruit trees or vegetables.

5. Fertigation Method: Use a drip irrigation system to deliver the fertilizer directly to the soil near crop roots. Effective in well-irrigated fields, this method enhances fertilizer utilization and reduces runoff.

6. Microencapsulation Technology: Encase the functional nitrogen fertilizer in microcapsules and deliver them to the root zone via irrigation systems. This improves stability and longevity, reducing volatilization losses.

7. Combination with Microbial Inoculants: Mix functional nitrogen fertilizers with microbial agents to boost fertilizer efficacy and promote crop growth.

Key Considerations for Using Functional Nitrogen Fertilizers:

1. Select Based on Crop Type and Growth Stage: For example, choose high-nitrogen formulations for nitrogen-demanding crops or high-phosphorus options for phosphorus-demanding crops.

2. Adjust Dosage According to Soil and Climate: Increase applications in low-fertility soils to boost yields, while reducing doses in fertile soils to avoid waste.

3. Optimize Timing and Methods: Apply fertilizer in the morning or evening to mitigate midday heat-induced decomposition. Use appropriate methods (e.g., basal, ditch, or hole application) to minimize soil disruption.

4. Post-Application Field Management: Timely irrigate, weed, and control pests after fertilization to ensure effective nutrient uptake.

the optimal use of functional nitrogen fertilizers depends on factors such as crop type, soil conditions, climate, and application objectives. Tailoring practices to these variables maximizes fertilization benefits.
