Definition (source: Our World in Data): Food and Agriculture Organization of the United Nations – Land, Inputs and Sustainability: Fertilizers by Nutrient. The Fertilizers by Nutrient dataset contains information on the totals in nutrients for Production, Trade and Agriculture Use of inorganic (chemical or mineral) fertilizers, over the time series 1961-2023. The data are provided for the three primary plant nutrients: nitrogen (N), phosphorus (expressed as P2O5) and potassium (expressed as K2O). Both straight and compound fertilizers are included. There is information on the methodology available at: https://files-faostat.fao.org/production/RFN/RFN_EN_README.pdf

Definition (source: Our World in Data): Fertilizer consumption measures the quantity of plant nutrients used per unit of arable land. Fertilizer products cover nitrogenous, potash, and phosphate fertilizers (including ground rock phosphate). Traditional nutrients--animal and plant manures--are not included. For the purpose of data dissemination, FAO has adopted the concept of a calendar year (January to December). Some countries compile fertilizer data on a calendar year basis, while others are on a split-year basis. Arable land includes land defined by the FAO as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land temporarily fallow. Land abandoned as a result of shifting cultivation is excluded. Note: Where data for 2023 is unavailable, the value from the closest year between 2020 and 2022 is shown instead.

Definition (source: FAOSTAT): Amount used in the agricultural sector in the year. Agricultural use of fertilizers refers to the use for crops, livestock, forestry, fisheries and aquaculture, excluding use for animal feed. Other plant nutrition uses (such as application to ponds, turf and ornamentals) would be excluded, but limited data availability currently prevents the discrimination of these uses. Therefore, it is assumed that those plant nutrition uses may also be included in the values for agriculture provided in this domain. Industrial uses, also known as technical uses, are excluded, to the extent allowed by data availability. Changes in stocks are not considered either, due to lack of information. The impact of stocks in the overall trend of the time series is assumed to be negligible.

Definition (source: Our World in Data): 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. The remaining 60% is lost to the environment as a pollutant. The data of this indicator is based on the following sources: Lassaletta et al. – 50 year trends in nitrogen use efficiency of world cropping systems: the relationship between yield and nitrogen input to cropland This dataset measures the nitrogen balance of agricultural inputs and outputs. Nitrogen inputs are measured as the application of nitrogen to crops either from synthetic fertilizers, or organic sources such as manure. Nitrogen output is measured as the nitrogen produced in the form of crops.
