N application rates from mineral fertiliser and manure

Historical N application rates from mineral fertiliser and manure. Prepared for Gridded Global Crop Model Intercomparison (GGCMI) project phase 3. 

Gridded time series of fertiliser application rates are based on national and sub-national estimates for 141 individual crops for the year 2000 from Mueller et al. (2012) and national time series for five different crop groups from LUH2v2 (Hurtt et al., 2020). Gridded time series of manure application rates on cropland are based on total applied manure per grid cell from Zhang et al. (2017) and cropland extent from LUH2v2 (Hurtt et al., 2020).

This update (v.1.1) corrects an error in the manure application rates, which was caused by a misalignment of manure data and cropland extent. Files for fertiser application rates are identical to the previous version.
