- Nitrogen-use efficiency refers to the yield of a crop relative to the amount of nitrogen available to it.
- Poor nitrogen-use efficiency results in substantial waste of nitrogen fertilizers, costing India ₹1 trillion annually and over $170 billion globally.
- Nitrogen fertilizers are a major source of pollution, contributing to harmful emissions and water contamination.
Importance of Nitrogen Use Efficiency
- Nitrogen-use efficiency is crucial for reducing the environmental impact of nitrogen pollution.
- Poor nitrogen-use efficiency leads to massive waste of nitrogen fertilizers, causing significant economic losses.
- Environmental concerns associated with low nitrogen-use efficiency include harmful emissions and water contamination.
