A wide variety of USDA soil orders were also found throughout the study area, including Inceptisols, Entisols, Vertisols, Andisols, Alfisols
, and Ultisols.
Pedogenic factors, especially the varying climate and topography, have caused the formation of various soil orders including Alfisols
, Mollisols, Aridisols, Entisols, and Inceptisols.

and ultisols of Western Kenya.
entisols, inceptisols, alfisols
and vertisols, are present in the study area.
Ukraine is mainly covered by three types of soil: alfisols
, mollisols, and entisols.
This is surprising since the kind of soil that dominates--Kancab in the local folk taxonomy, equivalent to Nitisols in the Food and Agriculture Organization of the United Nations (FAO) soil taxonomy and to Alfisols
in the United States Department of Agriculture (USDA) system of classification--are ranked among the best for cultivation in the northern Maya lowlands (Dunning 1992; see also Driessen et al.
Soils included Mollisols, Vertisols, Alfisols
, and Entisols (Hatch and Pluhar, 1993).
It looked bewilderingly complex, covered in soil groups with names such as alfisols
, common in forests, and histosols, found in peat bogs.
More local soils include entisols (especially on more recent colluvium/alluvium), inceptisols (especially on deep/damp colluvium/alluvium), mollisols (presumably with more stable grass, cane or cedar cover), and alfisols
(on more weathered loamy uplands with more woodland history just above the chalk).
These conclusions reinforce why nitrate leaching of temperate climate soils, such as Mollisols, Alfisols
, Vertisols, Aridisols, will be favored throughout the soil profile (BAKHSH et al.

Pre-mining soils are largely order Alfisols
and Subgroup Typic Fragiudalfs (Miles and Weiss, 1978) including infertile fragipan and claypan soils.
