摘要

The study quantified spatial variability in exchangeable basic cations in soils of forested hilly terrain in 2006. A transect technique was used in aligning profile pits along three physiographic units of interfluve, colluvial footslope and channel bed. Collected soil samples from the profile pits were analysed using routine and special laboratory techniques. Soil data were subjected to conventional and geostatistical analyses. Exchangeable cations varied spatially and vertically irrespective of physiographic position. Strong degree of spatial dependence was exhibited by these cations in epipedal horizons while moderate degree of spatial dependence dominated in their subsurface distribution using nugget values. Values of coefficient of variation confirm pronounced anisotropy among these attributes in their vertical distribution. Studies in exchange chemistry and other related edaphic properties using other multivariate techniques will enhance knowledge gained in this study.
