National survey data of manure nutrient input to cropland across China from 2005 to 2014

The data included the inputs of manure nitrogen (N), phosphorus (P), and potassium (K) for cereals, fruits, vegetables, and other crops, along with the manure proportion of total N, P, and K inputs at the county level. The national survey data of > 6.6 million farmers were collected from 2005 to 2014. the total manure N, P, and K input to the cropland for each crop type was extensively quantified at the county level. Second, based on county-level statistical data, the manure inputs for the four crop types were calculated. Finally, in combination with chemical fertilizer input data from the national survey, the county-level spatial variation of the proportion of manure input was established. Our results provide a clear perspective for manure nutrient management in agricultural production, as well as detailed support for environmental impact assessment at the spatial level in China.

本数据集涵盖县域尺度下粮食作物、果品、蔬菜及其他农作物的粪肥氮（N）、磷（P）、钾（K）投入量，同时包含粪肥占总氮、磷、钾投入总量的比例。本研究于2005至2014年间采集了覆盖超660万农户的全国性农户调查数据，并基于该数据在县域尺度上全面量化了各作物类型向农田投入的粪肥氮、磷、钾总量。其次，依托县级统计数据，核算了四类作物的粪肥投入量；最后，结合全国调查获取的化肥投入数据，构建了县域尺度粪肥投入占比的空间分异特征。本研究结果可为农业生产中的粪肥养分管理提供清晰的研究视角，同时为中国空间尺度的环境影响评估提供详实支撑。
