Characterization, Classification And Land Capability Evaluation Of Soils Of A Toposequence In Okwulaga Afaraukwu Umuahia, Abia State, Nigeria
ABSTRACT
A study was conducted to characterize,
classify and assess the potential of the soils of a toposequence for
sustainable crop production in Okwulaga Afaraukwu in Umuahia North Local
Government Area of Abia State, Southeast Nigeria and lies between latitudes 50291-50421
N and longitudes 70291-70331 E. The
toposequence was delineated into three physiographic units (upper slope, middle
slope and lower slope). A modal soil
profile was established in each of the units. The profiles were described
morphologically and soil samples collected from the identified horizons were
analyzed for physical and chemical properties. The soils were classified using
the USDA Soil Taxonomy and World Reference Base. Also, the USDA land capability
classification (LCC) was used to assess the potentials of the soils for arable
and non arable crops production. Results revealed variations in morphological,
physical and chemical properties of the soils. The soils of the upper slopes
were well drained and deep, the middle slopes were well drain at the topsoil
while the sub-soils were imperfectly drained and deep compared with the poorly
drained soils of the lower slope whose depth was limited by high water table at
the depth of 40cm.
