There are various methods to quickly supplement nitrogen fertilizer, with some common approaches listed below:

1. Apply nitrogen-containing fertilizers such as urea or ammonium bicarbonate. These fertilizers can be directly added to the soil to provide plants with essential nitrogen. When using, follow the recommended dosage on the instructions, as excessive application may cause overly rapid plant growth, which could be detrimental to their health.

2. Foliar spraying of nitrogen fertilizers. This method is suitable for plants requiring rapid nitrogen replenishment, such as fruit trees and vegetables. By spraying a nitrogen-containing solution onto plant leaves, nitrogen levels within the plants can be swiftly increased. Select a nitrogen solution appropriate for the plant species and apply according to the recommended dosage.

3. Use organic fertilizers. Organic matter in fertilizers can bind with soil nitrogen to form stable nitrogen compounds for plant absorption. For example, animal manure like chicken or cow dung, rich in nitrogen, can be used as organic fertilizer. When applying, control the dosage and method to avoid disrupting soil structure or microbial activity.

4. Add nitrogen sources. Incorporating nitrogen sources into the soil enhances its nitrogen supply capacity. Common nitrogen sources include urea, potassium nitrate, and ammonium sulfate. These can be applied by dissolving in water or mixing with soil. Follow product guidelines to prevent excessive use, which may increase soil salinity.

5. Adjust irrigation water quality. Groundwater or river water in some areas may contain high nitrogen levels, which could negatively impact crops if used directly. Consider using treated irrigation water or adding appropriate nitrogen fertilizers to dilute nitrogen concentrations.

6. Implement rational crop rotation. Rotation reduces nitrogen loss and improves nitrogen utilization efficiency. By alternating crops, some soil nitrogen is released for absorption by subsequent crops. Rotation types and durations should align with local climate, soil type, and crop needs.

7. Adopt biological nitrogen fixation techniques. Biological nitrogen fixation involves converting atmospheric nitrogen into ammonia using microorganisms (e.g., Rhizobia). Inoculating fields with nitrogen-fixing bacteria boosts soil nitrogen availability. this method requires time, investment, and is influenced by soil conditions and crop types.

8. Minimize nitrogen losses. Nitrogen easily depletes through volatilization, leaching, and runoff. To reduce losses:

   • Rational fertilization: Base fertilizer amounts and timing on crop needs and soil fertility to avoid excess.
   • Water source protection: Use water-saving irrigation methods and safeguard water bodies to prevent pollution-induced nitrogen entry.
   • Soil management: Improve soil’s water- and nutrient-retention capabilities; regularly test soil nitrogen content and forms for targeted measures.
   • Ecological balance: Maintain ecosystem equilibrium through crop diversification to reduce anthropogenic nitrogen loss.

numerous methods exist for rapid nitrogen supplementation, but the choice depends on specific circumstances. Before applying any method, consult professionals to ensure safe and effective nitrogen replenishment.
