The Agronomic fertilizer use efficiency in maize grain yield under three different fertilizer application rates plotted in the map was calculated as the average values of 7 years (the year 2004 -2010). The unit is kilogram per kilogram (kg/kg).
Agronomic fertilizer Use Efficiency (FUE)= (Maize grain yield under fertilized condition - Maize grain yield under unfertilized condition) (in kg)/ Fertilizer application rate (in kg)

The climate data at the national scale was made available from the National Aeronautics and Space Administration (NASA), Goddard Institute of Space Studies(https://data.giss.nasa.gov/impacts/agmipcf/agmerra/), AgMERRA.The dataset is stored at 0.25°×0.25° horizontal resolution (~25km).

Soil parameter values were extracted from the soil property maps of Africa at 1 km x 1 km resolution
