Description

Soil nitrogen (N), phosphorus (P) and potassium (K) supply effectively available for uptake (kg/ha), calculated as a fraction of the measured and mapped contents of N, P and K,  using the formulas proposed by Sattari (Sattari et al. 2014, DOI:10.1016/j.fcr.2013.12.005) and pedotransfer functions (PTFs) from the QUEFTS model (Janssen et al., 1990, https://doi.org/10.1016/0016-7061(90)90021-Z). The NPK input data is derived from Africa SoilGrids [Soil property maps of Africa at 250 m resolution] (https://doi.org/10.1007/s10705-017-9870-x) aggregated for the topsoil at 0-30 cm.
