| Popis: | Eight pedons representing the major soils found within the Guinea Savanna region of northern Nigeria were studied with respect to their important morphological, physical, chemical, and other characteristics, and their suitability for sustainable agricultural production was evaluated. The most important soil characteristics observed for separating the soils into mapping units include presence or absence of petroferric contact, effective soil depth especially to hardpan layer, gravel and subsoil clay content. Dominant pedogenic processes, which influence the rate of soil development in the area, include plinthization, clay eluviation‐illuviation, iron (Fe)‐oxyhydroxide release (lateral movement and enrichment), eolian deposition, and leaching. According to the USDA system of classification, the soils (MU‐EDA) in the summit to upper slope are classified as Lithic Haplustepts, those (MU‐EDB) at the midslope are Typic Haplustepts, the MU‐EDC (lower slope soils) as Dystric Haplustepts, and the MU‐EDD (... |
