A soil assessment was carried out in the savannah region of Togo in 2018, aiming at drawing the digital map of Togo’s soil fertility and making fertilizer recommendations. Soil samples were taken from geo-referenced GPS points and were analyzed for parameters such as water pH, Organic matter, available phosphorus and exchangeable potassium. Thematic maps have been drawn using an ArcGIS package. The results showed that the soils of the Savannah region in Togo are mainly (84%) not very acidic (pH = 5.5 to 6.5), overall poor to very poor (84%) in organic matter (<2% OM), essentially poor to very poor (86%) in available phosphorus (<15 mg/kg of soil) and mostly very poor (87%) in exchangeable potassium (<90 mg / kg of soil). These results allowed the agricultural research institute of Togo to make fertilizer use recommendations and to develop, in partnership with Morocco, a digital platform (fertitogo.tg ) for decision making in crop fertilization.
