Geoinformatic technique based land suitability assessment was used to classify
Ikpoba River basin, a Rain Forest River basin in Nigeria into land suitability zones
for the optimum cultivation of maize, cassava, yam and oil palm, based on the Food
and Agriculture Organisation (FAO) guidelines and suitability model. This is in an
attempt to attain a precision farming structure for the forest river basin. The
technique entails overlay analysis of land use land cover characteristics interpreted
on Landsat TM imagery and physico-chemical soil properties as well as nutrient
attributes within GIS framework. Established land suitability cultivation ratings for
selected crops were derived from the integration of the established crop
requirements, land use land cover and soil physic-chemical and nutrient layers. The
result revealed areas of high, moderate and marginal suitability for the cultivation
of maize, yam, cassava and oil palm, which could serve as basis for further analysis
and selection of parcels of land for precision farming in the basin.
