Reactive Nitrogen Assessment in South Asia

The nitrogen (N) cycle is anthropogenically the most disturbed nutrient cycle having adverse impacts on majority of ecological compartments and resultant ecosystem services. Such perturbations adversely impact food security, energy, industry, human health, biodiversity, environment and climate change. Reactive nitrogen (Nr) includes inorganic (from both sides of the redox range, including NH₃, NH₄⁺, NO_x, N₂O, NO₂^-, NO₃^-) and organic (urea, amines) variants that readily interact in the environment.
