Despite being the most prevalent atmospheric element, nitrogen presents a paradoxical challenge for agriculture. While plants require large quantities, only a small fraction is readily available for uptake. Most nitrogen exists as inert dinitrogen gas (N2), unusable by most organisms. However, transformations occur, converting it into more reactive forms like nitrate (NO3-) and ammonium (NH4+). These forms are highly mobile in water and air, leading to potential losses through leaching, runoff, volatilization, and denitrification in both upland (leaching, run-off) and lowland (denitrification, volatilization) soils. Effective nitrogen management is crucial for optimal crop growth and minimizing environmental losses. This necessitates implementing various strategies to enhance Nitrogen Use Efficiency (NUE).
