Nitrogen use efficiency (NUE) is the ratio between nitrogen inputs and output. A NUE of 40% means that only 40% of nitrogen inputs are converted into nitrogen in the form of crops.
Total nitrogen inputs to crops; Which countries overapplied nitrogen without gains in crop yields? World population supported by synthetic nitrogen fertilizers; World population with and without synthetic nitrogen fertilizers
For world’s sustainable food production and atmospheric benefits, there is an urgent need to up-grade nitrogen use efficiency in agricultural farming system. The nitrogen use efficiency is the product of nitrogen uptake efficiency and nitrogen utilization efficiency, it varies from 30.2 to 53.2%.
22 sty 2024 · We present a global database of country-level budget estimates for nitrogen (N), phosphorus (P) and potassium (K) on cropland. The database, disseminated in FAOSTAT, is meant to provide a global reference, synthesizing and continuously updating the state of the art on this topic.
3 sty 2017 · Power point presentation given by the EU Nitrogen Expert Panel about nitrogen use efficiency.
1 lis 2024 · LCC, sensors, GIS, GPS, data analysis, VRT, and crop models enable real-time N monitoring and precise N application. Real-time N detection optimizes fertilizer use, cuts waste, and reduces environmental impact. Improved nitrogen-use efficiency sustains agriculture with optimal yields.
18 maj 2021 · Nearly half of N fertilizer input is not used by crops and is lost into the environment via emission of gases or by polluting water bodies. It is essential to achieve production levels, which enable global food security, without compromising environmental security.
