Environmental friendly nitrogen fertilization

Area of Science:

• Agricultural Science
• Environmental Science
• Agronomy

Background:

• Intensified agriculture necessitates sustainable practices for environmental and human health.
• Growing demand for eco-friendly nitrogen (N) application methods to support land use and food production.

Purpose of the Study:

• To review and analyze environmentally friendly nitrogen application approaches.
• To examine the agronomic and environmental significance of these N application strategies.
• To assess the relevance of these methods for different farming scales and sophistication levels.

Main Methods:

• Literature review of current nitrogen application techniques.
• Analysis of action mechanisms for each approach.
• Evaluation of agronomic and environmental impacts.

Main Results:

• Key approaches include improved application modes (split/localized), bio-amendments (inhibitors), controlled/slow-release fertilizers, fertigation, and precision fertilization.
• Effectiveness depends on synchronizing N supply with plant demand and appropriate N-species composition/dosage.
• Methods vary in applicability based on farming scale and technological sophistication.

Conclusions:

• A range of innovative nitrogen application strategies support sustainable agriculture.
• Optimizing N use efficiency is crucial for balancing food production with environmental protection.
• Tailoring approaches to specific farming contexts is essential for successful implementation.
