Global dataset on nutrient removal with crop residues

This dataset provides global, annual estimates of how much nitrogen, phosphorus, and potassium are removed from cropland through the off-field removal of crop residues. It covers 210 countries from 1961 to 2023, based on information from official statistics, expert knowledge, and published sources. The dataset has been integrated into the FAO Cropland Nutrient Balance Database as of the 2025 release, enabling more complete assessments of nutrient balances and nutrient use efficiency.

## 1. Background and methods

Crop residues are the parts of the plant that remain in the field after harvest. Previous versions of the [FAO - Cropland Nutrient Balance Database (FAO-CNB)](https://www.fao.org/faostat/en/#data/ESB) only provided estimates of nutrient outputs through the harvested organs, but not for nutrient outputs associated with crop residue removal. When residues are removed from the field for other uses, such as off-field livestock feeding, bedding, fuel or mushroom cultivation, considerable amounts of nitrogen (N), phosphorus (P), and potassium (K) are removed out of the system. Nutrients may also be lost due to in-field residue burning. In contrast, nutrients in crop residues are recycled in the agroecosystem when they are used for grazing within the field or left to decompose above or below ground.

本数据集提供全球尺度下，通过作物残体移出农田的方式所带走的氮、磷、钾养分的年度估算值。数据集覆盖1961年至2023年的210个国家，数据来源于官方统计资料、专家经验及已发表文献。截至2025版发布，本数据集已整合至粮农组织农田养分平衡数据库（FAO Cropland Nutrient Balance Database, FAO-CNB），可支撑养分平衡与养分利用效率的更全面评估。

# 作物残体养分移出全球数据集

## 1. 研究背景与方法

作物残体指收获后留存于农田的植物剩余部分。此前版本的[粮农组织农田养分平衡数据库（FAO Cropland Nutrient Balance Database, FAO-CNB）](https://www.fao.org/faostat/en/#data/ESB)仅提供通过收获器官所产生的养分输出估算，未涵盖与作物残体移出相关的养分输出。当残体被移出农田用于其他用途时，例如用于场外畜禽饲喂、垫料、燃料或食用菌栽培，大量的氮（N）、磷（P）和钾（K）会从农业系统中被移出。此外，田间残体焚烧也会造成养分损失。与之相对，若作物残体被用于田间放牧，或留在地表、地下自然分解，则其携带的养分可在农业生态系统中实现循环利用。
