Relationship between pedogenetic manifestations in some arid soil and age of the landforms
- 23 Downloads
Arid soils with slight variations in parent material, vegetation and climate were studied for their morphological, chemical and mineralogical characteristics. Results show that the soils are at different stages of profile development. Varying degrees of pedogenic features have been tied up with data on palaeoenvironment to develop a relationship between the soil and age of the landform. Studies reveal that Dune and Shergarh sandy soils with least degree of manifestation belong to early Holocene to latest Pleistocene, whereas Chirai sandy soil with weakly developed B horizon belongs to the upper Holocene. Soils (Khajwana and Gajsinghpura) with well-developed B horizon and a calcic layer with lime segregations belong to mid-Pleistocene whereas Pali and Pipar soils with illuvial clay in B horizon belong to early Pleistocene.
