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 effic...,
Details of how the Cropland Nutrient Budget data were collected and processed are described by Ludemann et al. (2024).

农业养分预算可用于识别肥料及其他养分源的施用过量或不足情况。养分预算可估算养分平衡（盈余或亏缺）、养分利用效率等指标，此举有助于全球范围内的农业生产力与可持续性监测。本数据集为全球农田氮（N）、磷（P）、钾（K）养分预算国别估算值数据库。该数据库依托联合国粮食及农业组织统计数据库（FAOSTAT）发布，作为全球参考基准，系统整合并持续更新该领域的前沿研究成果。该数据库涵盖1961年至2020年时段，覆盖205个国家和地区以及区域、全球汇总数据。研究结果显示，不同区域、养分类型与时段间的养分施用及利用效率存在显著差异。本数据集针对影响养分预算与利用效率的关键养分系数相关研究，相较此前工作实现了优化完善。农田养分预算数据的采集与处理流程详情参见Ludemann等人（2024）的研究。
