FAO ResourceSTAT, Food and Agriculture Organization of the United Nations; Proportions calculated by UNSD Environment Statistics Section.
- When the Fertilizer Utilization Account (FUA) does not balance due to utilization from stockpiles, apparent consumption has been set to zero.
Definitions & Technical notes:
Proportions of use of fertilizers (by nutrient group) per unit of agricultural land area are calculated by UNSD using available consumption and land use data from FAOSTAT. The indicator units are tonnes of nutrients per 1000 hectares (or 10 km2) of agricultural land area for each country or area.
Fertilizers use refers to the consumption of the three main types of nutrients used: Nitrogen (N), Phosphate (P2O5) and Potash (K2O). Data are either official as reported to FAO through the Fertilizers and Land and Irrigation questionnaires (http://www.fao.org/es/ess/questionnaires/default.asp) or obtained as a balance or otherwise estimated by FAO and other expert sources. For more information on individual values and calculations visit the FAOSTAT ResourceSTAT website.
Definitions for land areas can vary across countries. For more information on the country/area calculations for agricultural area visit the FAOSTAT ResourceSTAT website.
In some cases, a portion of fertilizer consumption may be for purposes unrelated to agricultural land. Therefore, the proportions should be treated as estimations.
