Global Fertilizer and Manure, Version 1: Phosphorus Fertilizer Application

The Phosphorus Fertilizer Application data set of the Global Fertilizer and Manure, Version 1 Data Collection represents the amount of phosphorus fertilizer nutrients applied to croplands. The national-level phosphorus fertilizer application rates for crops are from the International Fertilizer Industry Association (IFA) "Fertilizer Use by Crop 2002" statistics database that is available by request from the Food and Agriculture Organization (FAO).The number of crop-specific fertilizer application rates reported for each country ranged from 2 crops (Guinea) to over 50 crops (United States), and the years for which the data are reported range from 1994 to 2001. Spatially explicit fertilizer inputs of Nitrogen (N) were computed by fusing national-level statistics on fertilizer use with global maps of harvested area for 175 crops. The data were compiled by Potter et al. (2010) and are distributed by the Columbia University Center for International Earth Science Information Network (CIESIN).

全球肥料与粪肥应用数据集版本1的磷肥应用数据集，详尽地记录了施加于农田的磷肥营养素总量。该数据集中国家层面的作物磷肥应用率数据来源于国际肥料工业协会（IFA）的《2002年作物肥料使用》统计数据库，该数据库可通过粮食及农业组织（FAO）的请求获取。各国报告的作物特定肥料应用率数量介于2种作物（几内亚）至50多种作物（美国）之间，数据报告的年份跨度从1994年至2001年。通过融合国家层面的肥料使用统计数据与全球175种作物的收获面积地图，计算了具有空间明确性的氮肥（N）投入量。该数据集由Potter等（2010）汇编，并由哥伦比亚大学国际地球科学信息网络中心（CIESIN）分发。
