It is widespread on rocky areas and is grown on different soil associations, including alfisols, regosols, and lithosols.
15.
Because of their productivity and abundance, the Alfisols represent one of the more important soil orders for food and fiber production.
16.
In eastern North America, Alfisols are commonly found in glaciated areas while Ultisols are restricted to the areas south of the limit of maximum glaciation.
17.
The district is dominated by Alfisols and sod-calcareous loamy soils that have high natural fertility and are some of the best soils in Udmurtia.
18.
Alfisols and ultisols emerged in the late Devonian and early Carboniferous, and have a continuous, though not rich, fossil record in eras since then.
19.
The above soil orders in sequence of increasing degree of development are Entisols, Inceptisols, Aridisols, Mollisols, Alfisols, Spodosols, Ultisols, and Oxisols.
20.
A wide range of soil fertility exists as evidenced by soil orders-Alfisols and Mollisols which are medium to high in base saturation to Ultisols which are low in base saturation ( 24 ).
