Type: Research



Soil Survey and Evaluation of an approximately total area of 25.58km2
of Obosi land was carried out, using the map of the area. The aims of the
research were to map out the soils of Obosi, classify and evaluate them for
suitability and sustainability for agricultural production and other land
use development projects, and to inventory the causes of the prevalent soil
erosion and the general land degradation of the area. Auger samples and
profile pits samples were collected and examined based on the morphology and
the relief of the surveyed area three mapping units: MUI – Lowland areas,
MUII – Upland areas and MU III – Gullied areas were established. From the
results obtained it was found out that the lowland areas and the upland
areas were suitable for arable crops. Their major shortfall for agricultural
production is low fertility. The Gullied areas, MUIII is physically found
within the uplands and low-land areas. They are referred to as badlands. The
prominent limitation of this unit is erosion hazard. The area cannot be used
in their present state without serious reclamation activity. The soils are
generally Iso-thermic udult (ultisols) by USDA classification and correlated
as Eutric Ferralsols by FAO – WRB classification. Efforts made through
interviews and consultations to inventory the causes of the prevailing land
degradation and soil erosion in Obosi revealed that so many factors such as
massive and sudden deforestation of the area, the topography and relief of
the area, the erodibility of Obosi soils and the poor government
intervention, all contributed immensely to the land degradation problems of
the area, and appropriate recommendations were made.
