Soil Mapping and in - Situ Soil Description of Selected Land Area of Funtua, Nigeria

Shobayo A.B.,*, Sulaiman Yau Lawan, Tarfa, B.D.

The study was done to delineate soil mapping units and produce the soil map of a selected 10 000 ha land. Landsat imagery of the study area was acquired and used for land cover and land use identification. Digital Elevation Models (DEM) of 10 m resolution was also obtained to produce landforms and contour maps. A 10 000 ha land was delineated from the landform map and divided with grids at 400 m i...
