Data from: A global FAOSTAT reference database of cropland nutrient budgets and nutrient use efficiency (1961–2020): nitrogen, phosphorus and potassium

Agricultural nutrient budgets help to identify an excess or an
insufficiency in use of fertilizers and other nutrient sources. Nutrient
budgets allow for indicators such as the nutrient balance (surplus or
deficit) and nutrient use efficiency to be estimated. This can help in the
monitoring of agricultural productivity and sustainability globally. The
present dataset is a global database of country-level budget estimates for
nitrogen (N), phosphorus (P) and potassium (K) in cropland. The database
is disseminated in FAOSTAT and provides a global reference, synthesizing
and continuously updating the state-of-the-art on this topic. The database
covers the period 961 to 2020 for 205 countries and territories, as well
as regional and global aggregates. Results indicate the wide range in
nutrient use and use efficiencies across regions, nutrients, and time.
This dataset introduces improvements over previous work in relation to key
nutrient coefficients affecting nutrient budgets and use efficiency
estimates. This is especially for nutrient removal in crop products,
manure nutrient content, atmospheric deposition and crop biological N
fixation rates.
