Luvisols and Lithosols
occupy a larger area (32%), mainly on top of the crystalline shield and have TOC between 10.
Comparative effects of separate incorporation of cowdung and rice-husk materials on nutrient status of some lithosols
in mubi, N.
Lithology comprises schists, quartzites, and tertiary 'rana' deposits, over which develop Lithosols
and Humic and Distric Cambissols.
These are Lithosols
, which are rocky, shallow, and infertile soils.
The talus slopes are mostly lithosols
All of the rocks have three classes of rarity, whereas the Lithosols
have mostly steppe or desert plants and only a few common rock plants.
Soils of most of the study area are immature lithosols
on the steep slopes of the range.
The dominant soil type of these two hillslopes is shallow lithosols
according to the FAO soil classification (Orthents according to Soil Taxonomy) and the parent material is quartz sandstone.
With respect to soils, BERKAT AND TAZI (2006) report that brown soils and rendzinas are dominant in the Middle Atlas with lithosols
and regosols on steep slopes.
It is widespread on rocky areas and is grown on different soil associations, including alfisols, regosols and lithosols
Classified by the GSG, the soils include Lithosols
, Red Earths, Yellow Earths, Red Podsolics, Yellow Podzolics, Solodic soils, Soloths, Red-brown Earths, and Alluvial soils.
Decalcification, leaching and gleying are the dominate soil-forming processes in the study area and the soils mainly comprise Grey Brown Podzolics, Brown Podzolics, Brown Earths, Gleys, Rendzinas and Lithosols
(Gardiner and Radford 1980).
