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

description: 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.
