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
In this report, fertilizers data are provided with respect to the three primary plant nutrients: nitrogen (N), phosphorus (P) and potassium (K). Data related to each of these nutrients are all expressed in the same units, as follows: » Nitrogen and ammonia: expressed as N » Phosphorus and phosphoric acid: expressed as P 2 O 5
11 wrz 2023 · To provide input data for the land surface models for assessing the effects of agricultural N fertilization practices on food security, climate change and ecosystem health, we developed a new...
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.
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 ...
Nitrogen is an important raw material for the chemical and fertilizer industries. Almost all nitrogen products are derived from ammonia, and about 85 percent goes to .
