Nigerian Journal of Science. An outline of northern Nigerian Soils [texte imprimé] / Klinkenberg, K. ; Higgins, G.M. . - sept-68. ISSN : CI-10027 The soils of northern Nigeria are described in term's of d'Hoore's legend yo the soil map of Africa and the distribution of the various categories is descrited in map form. It appears that ferruginous tropical soils are the normale product of soil for most of northern Nigeria. Under drier-than-average conditions brown and reddish brown soil arid and semi-arid regions are found while ferrallitic soils and ferrisols occur in areas with a higher an better distributed rainfall. In some areas particular lithological conditions have an overriding influence or pedogenetic processes and vertisols and eutrophic brown soils are formed. Juvenile soils are found on recente deposits, where the depogenetic processes have not been active enough to exibit any effect. Langues : Anglais (eng)
