Environmental friendly nitrogen fertilization

Area of Science:

• Agricultural Science
• Environmental Science
• Agronomy

Background:

• Intensified agriculture necessitates sustainable practices for environmental and human health.
• Growing awareness drives the development of eco-friendly nitrogen (N) application methods.
• Effective N management is crucial for sustainable land use and food production.

Purpose of the Study:

• To review and analyze environmentally friendly nitrogen application approaches.
• To examine the mechanisms, agronomic, and environmental significance of these N management strategies.
• To assess the applicability of these methods across different farming scales and sophistication levels.

Main Methods:

• Review of scientific literature on advanced N application techniques.
• Analysis of bio-amendments, controlled-release fertilizers, and fertigation systems.
• Examination of precision fertilization in large-scale farming.

Main Results:

• Key approaches include split/localized application, bio-amendments (nitrification/urease inhibitors), controlled/slow-release fertilizers, fertigation, and precision fertilization.
• These methods aim to synchronize N supply with plant demand, enhancing efficiency.
• Agronomic and environmental impacts vary based on the specific approach and farming context.

Conclusions:

• Eco-friendly N application strategies are vital for sustainable agriculture.
• The choice of method depends on farming scale, intensification, and technological sophistication.
• Optimized N management supports both food security and environmental protection.
