Abstract 

A soil survey analysis using terrain ruggedness and normalized difference vegetation index (NDVI) of Wafongo-Yola Terrain, Northeast Nigeria was conducted to examine and characterize geographic bodies such as vegetation, soils and terrain features which play an important role in evaluating soils conditions for agricultural production. In agriculture, a regional reconnaissance soil survey is usually carried out to identify soils that may support agricultural production. The Terrain Rugged Index Analysis showed the top right quadrant through to the top left quadrant and down the bottom left quadrant at a higher level of abstraction appeared homogeneously leveled. This confirms the earlier suggestion that the area could support agricultural production having a regular terrain and vegetative cover. Terrain Ruggedness Index values of 0.00 to 2.00 were regarded as leveled, 2.00 to 6.00 as nearly leveled which could support agricultural cultivation and values >6.00 are considered to be rugged and might need erosion control measures in the study area.
