1、Final

Recommendations for the management of GHGs, in addition to energy efficiency and conservation, are addressed in the General EHS Guidelines. Process emissions from urea plants consist mainly of ammonia (NH3) and dust. Fugitive emissions of NH3 from tanks, valves, flanges, and tubing may also occur.

2、Hazards of nitrogen fertilizers and ways to reduce nitrate accumulation

Since the beginning of nitrogen fertilizers in agriculture, researchers are attempting to devise different approaches to reduce the availability of nitrate content in soil for plant uptake.

3、Towards precise nitrogen fertilizer management for sustainable

Effective nitrogen (N) fertilizer management is crucial for meeting the growing demand for crop production while maintaining planetary boundaries within sustainable limits.

Nitrogen Fertilizer Management & Greenhouse Gas Mitigation Opportunities

Use of synthetic nitrogen fertilizer can be reduced as discussed above by optimizing the 4 Rs of fertilizer use, using other available sources of nitrogen such as manure, crop residues, and cover crops, and developing and using a comprehensive nutrient management plan as discussed below.

Nitrogen fertilizers and the future of sustainable agriculture: a deep

Governments and researchers in various countries have implemented measures from three perspectives, namely ‘source control, process management, and terminal treatment,’ in order to mitigate agricultural nitrogen pollution.

Nitrogen fertilizers are indispensable in agricultural production and critical for crop growth. excessive use of nitrogen fertilizers can harm the environment, necessitating preventive and control measures to reduce overuse. The following measures outline effective strategies:

1. Rational Fertilization: Determine nitrogen dosage and timing based on crop growth stages and soil fertility. Avoid overapplication to prevent nitrogen surplus, soil acidification, and salinization. Combine organic fertilizers with chemical ones to balance nutrients and improve soil health.

2. Promote Slow-/Controlled-Release Nitrogen Fertilizers: These fertilizers release nitrogen gradually, reducing losses from volatilization or leaching. Apply them during sowing or early growth stages to align with crop nitrogen demands.

3. Improve Fertilization Methods: Use deep placement, drill application, or hole application to distribute nitrogen evenly. Avoid mixing nitrogen with phosphorus or potassium fertilizers to prevent reduced absorption efficiency.

4. Enhance Field Management: Perform timely mid-cultivation, weeding, and soil loosening to improve aeration and root development, boosting nitrogen uptake. Strengthen pest and disease control to minimize nitrogen loss.

5. Establish Monitoring Systems: Regularly test soil nitrogen content to guide rational fertilization. Adjust strategies based on monitoring data to ensure crops receive optimal nitrogen.

6. Adopt Water-Saving Irrigation: Implement drip or sprinkler irrigation to reduce water loss and lower nitrogen needs. Optimize irrigation schedules to enhance water use efficiency.

7. Develop Ecological Agriculture: Grow green manure and leguminous forage crops to increase soil organic matter and nitrogen supply. Use crop rotation and intercropping to improve soil structure and fertility.

8. Strengthen Scientific Research: Address challenges in nitrogen use through innovation. Develop advanced slow-/controlled-release products and precise soil nutrient monitoring technologies.

9. Raise Awareness and Education: Train farmers and distribute materials to promote scientific nitrogen use. Discourage blind pursuit of high yields at the cost of soil health.

10. Policy Support and Guidance: Governments should incentivize sustainable practices, support organic fertilizer research, and encourage eco-friendly farming transformations.

prevention and control measures for nitrogen fertilizers include rational fertilization, improved application methods, field management, monitoring systems, water-saving techniques, ecological agriculture, research innovation, education, and policy guidance. These efforts collectively reduce overuse, protect the environment, and advance sustainable agriculture.
