Abstract

A study was conducted to evaluate the morphological and physical characteristics of a soil devel-oped on a toposequence using fire slope positions. Modal profile pits were dug in each of the slope positions and characterized. Soil samples were collected from each of the pedogenetic horizons and analyzed routinely for particle size distribution of bulk/particle densities and total porosity. Results showed that the landscape had a relative elevation of 0-24. 25 m with a slope gradient value from the crest to valley bottom as: 1.68, 1.55, 1.46, 1.42 and 1.22%. Soil colour from the crest to the valley bottom varied significantly from dominant 5YR to 7.5 YR and 10YR respectively. Soil depth, structure, consistence and rootlets varied significantly (P ≤ 0.05) across slope position. Bulk and particle densities value were higher in the crest and upper-slope positions with mean values of 1.20 gcm-3 and 2.35 gcm-3. There were no significant variations (P > 0.05) in particle size distribution across slope position.
