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.
Fertilizers supply plants with nutrients that are essential for growth. Fertilizers have played an essential role in feeding a growing global population. It's estimated that just under half of the people alive today are dependent on synthetic fertilizers. They can bring environmental benefits too: fertilizers can increase crop yields.
Explore the use and impact of fertilizers across the world.
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.
11 wrz 2023 · Our spatiotemporal N fertilization dataset could be used for the land surface models to quantify the effects of agricultural N fertilization practices on food security, climate change, and...
vi Technical notes on supply, demand and balances In this report, fertilizers data are provided with respect to the three primary plant nutrients: nitrogen (N), phosphorus (P) and potassium (K).
26 lis 2024 · These important statistics allow assess, for each country of the world, the impacts of fertilizers use in relation to the needs of crop production. Along with information on individual input and output components of the nutrient balance, the FAOSTAT data provide information on nutrient use efficiency (NUE), a critical indicator that helps ...
