Agronomic Fertilizer Use Efficiency (FUE) (Map) in Maize biomass in Ashanti region and Brong-Ahafo region in Ghana (Map) under three fertilizer application rates i.e., 4 kg/ha Nitrogen (current application rates); 45 kg/ha Nitrogen and 15 kg/ha Phosphorous; 135 kg/ha Nitrogen and 45 kg/ha Phosphorous, 1992-2010

Agronomic Fertilizer Use Efficiency (WUE) for maize biomass in Ashanti region and Brong-Ahafo region in Ghana has been estimated under three different fertilizer application rates using crop model LINTUL5 embedded into the modeling framework SIMPLACE (Scientific Impact Assessment and Modelling Platform for Advanced Crop and Ecosystem Management. Quality/Lineage: The Agronomic fertilizer use efficiency in maize biomass under three different fertilizer application rates, plotted in the map was calculated as the average values of 19 years (the year 1992 -2010).

The unit is kilogram per Kilogram (kg/kg). Agronomic fertilizer Use Efficiency (FUE)= (Maize biomass under fertilized condition - Maize biomass under unfertilized condition) (in kg)/ Fertilizer application rate (in kg) The climate data at the national scale was made available from the Terrestrial Hydrology Research Group, Princeton University (hydrology.princeton.edu/data.php) at a resolution of 10 km x 10 km. The dataset was constructed by combining a suite of global observation-based datasets with the NCEP/NCAR reanalysis.
