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: The World Bank): A measure of annual emissions of nitrous oxide (N₂O), one of the six Kyoto greenhouse gases (GHG), from the agricultural sector. This includes emissions from livestock (IPCC 2006 codes 3.A.1 – enteric fermentation, 3.A.2 – manure management) and crops (IPCC 2006 codes 3.C.1 – emissions from biomass burning, 3.C.2 – liming, 3.C.3 – urea application, 3.C.4 – direct N₂O emissions from managed soils, 3.C.5 – indirect N₂O emissions from managed soils, 3.C.6 – indirect N₂O emissions from manure management, 3.C.7 – rice cultivation). The measure is standardized to carbon dioxide equivalent values using the Global Warming Potential (GWP) factors of IPCC's 5th Assessment Report (AR5).
