Abstract
Grumusols in Kenya comprise black, grey and brown soils and occur on Pleistocene lake clays, alluvium, volcanic ash, basic lava and tuffs, and even Precambrian gneisses and schist. They occupy about 116,000 hectares in the Kano Plains where they primarily derive from Pleistocene lake sediments which have been largely eroded and redistributed to form a variable alluvium under conditions of Impeded drainage and seasonal flooding. The soils occupy level or slightly sloping situations but drainage impedance is such that a local depression of only a few centimetres is subject to seasonal waterlogging.
