MFM

Global gridded N, P₂O₅, K₂O application rates [kg/ha of crop harvested area] for 141 crops and pastures at a resolution of 0.0833 degree (~10 km at the equator); reference year 2000.

Input

^25,48

Briefly, data was estimated based on national and subnational statistics collected from various international organisations and NSOs, and spatialized based on MRF crop masks. Data granularity at subnational and national levels, i.e., pixel values are uniform in a whole subnational or national unit. Data granularity in a country varies among crops and nutrients. Data quality varies greatly across geographical areas, crop types, and nutrients, depending on the availability of input data.
