Potential source here. Perhaps the data hunting exercise at GEE has yielded something better?

These data are needed to estimate the available water storage capacity in effective rainfall and the average crop water demand.

List of soil parameters (250 m) – might add/remove some (i.e. DRAINFAO as it is a categorical variable).

Africa SoilGrids - Clay content - CLYPPT Clay content (0-2 micro meter) in g/100g (w%) at 6 standard depths predicted using two sets of Africa soil profiles data.

Africa SoilGrids - Soil pH in H2O - PHIHOX Soil pH x 10 in H2O at 6 standard depths (to convert to pH values divide by 10) predicted using two sets of Africa soil profiles data. Measurement units: NA.

Africa SoilGrids - Drainage classes – DRAINFAO Drainage classes, defined according to the Guidelines for Soil Description (FAO, 2006) predicted using the Africa Soil Profiles Database (AfSP) v1.2. LEGEND = 1:Very poor, 2:Poor, 3:Imperfect, 4:Moderate, 5:Well, 6:Somewhat excessive, 7:Excessive, 255:NODATA.

Africa SoilGrids - Depth to bedrock - BDRICM Depth to bedrock (R horizon) in cm, to maximum 175 cm, predicted using two sets of Africa soil profiles data

Africa SoilGrids - Bulk density (BD) - BLD Bulk density of the soil fine earth (measured by core method) in kg / cubic-meter (kg/m3) at 6 standard depths predicted using the Africa Soil Profiles Database (AfSP) v1.2.

Africa SoilGrids - Texture - TEXMHT Textural class (defined according to USDA system) at 6 depth intervals derived from sand, silt and clay contents predicted using the Africa Soil Profiles Database (AfSP) v1.2.

Africa SoilGrids - Soil organic carbon (SOC) - ORCDRC Soil organic carbon content (measured by either wet oxidation or dry combustion at 900 C) in g/kg (fine earth) at 6 standard depths predicted using two sets of Africa soil profiles data.
