Fertilizer and Manure Version 1
The Global Fertilizer and Manure, Version 1 data represent fertilizer application rates and manure production of Nitrogen (N) and Phosphorous (P). Spatially explicit fertilizer inputs were computed by fusing national-level statistics on fertilizer use with global maps of harvested area for 175 crops. Manure production was based on livestock head count and nutrient content of manure. The data were compiled by Philip Potter and Navin Ramankutty, et. al. (2010).
