This soil was classified as Eutric Fluvic Arenosols
with weak features of illuviation process development and sand and clay contents of 70.5-86.4% and 0.3-2.6%, respectively.
Soils in MMUST and Kisumu are generally classified as Nitisols and Arenosols
, respectively .
In the sandy covers located dominantly in the upper parts, at least 60% of the soils are classified as Arenosols
of the World Reference Base for Soil Resources (WRB) classification system (IUSS Working Group WRB, 2007).
From the viewpoint of soil diversity, aeolian dune sediments (7 sampling plots), where Arenosols
(6 sampling plots) and Podzols (1 sampling plot) are common, are relatively homogeneous (Table 1).
The soils in the catchment with the 30 households are well-drained, deep, yellowish brown, loamy sand to sandy loam (Luvic Arenosols
) (Muya, 2003).
Types such as cambic arenosols
(qc), rhodic ferralsols with fine texture in hilly to steep regions (frFHS) and calcic yermosols with coarse to moderate texture and in undulating to hilly regions (ykCMUH) were identified as high productivity soils.
The caatingas at La Esmeralda are developed on albic arenosols
, characterized by a layer of humus-rich sand (mean loss on ignition = 21%) [approximately]40 cm thick, overlying a bleached white-sand E horizon in which there are very few fine roots.

in Bindura and Shamva district of Zimbabwe.
and Regosols were grouped into "non-developed soils" and Chernozems, Phaeozems, Kastanozems and Vertisols into "mollic soils".
