Global Fertilizer and Manure, Version 1: Phosphorus in Manure Production

The Phosphorus in Manure Production data set of the Global Fertilizer and Manure, Version 1 Data Collection represents the amount of phosphorous in manure produced and present on the landscape. The manure production at grid cell level was computed based on livestock population and nutrient excretion rates. The livestock population per grid cell was computed by multiplying the density values from FAO Gridded Livestock of the World by the area of grid cell. Spatially explicit manure produced and present on landscape is derived by combining the number of livestock heads and the nutrient excretion rate. The data were compiled by Potter et al. (2010) and are distributed by the Columbia University Center for International Earth Science Information Network (CIESIN).

全球肥料与粪便数据集（版本1）中的磷素含量数据集，描绘了粪便生产及存在于景观中的磷素总量。该数据集基于家畜数量及养分排泄率，在网格单元级别计算粪便生产量。每个网格单元的家畜数量通过将联合国粮食及农业组织（FAO）的全球网格化家畜密度值与网格单元面积相乘得出。空间上具体的粪便产生及存在于景观中的数量通过结合家畜头数与养分排泄率计算得出。该数据由Potter等人（2010年）编制，并由哥伦比亚大学国际地球科学信息网络中心（CIESIN）分发。
