Soils in MMUST and Kisumu are generally classified as Nitisols and Arenosols, respectively [13].
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).
Arenosols are sandy-textured soils that lack any significant soil profile development.
All studied stands were growing on nutrient-poor sandy Arenosols (forest type - Vaccinio - myrtillo Pinetum).
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).
Arenosols were characterized by Fe/Al-P as dominant sparingly soluble P-fraction and contained PCAL (5.
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.
