Study of Pedo Genesis of soils of Bundi district (Rajasthan)

The soils of Rajasthan vary from desert sand to heavy clay with all intermediate stages like sandy loam, loam and clay loam. The last two textural groups are more prevalant on the eastern, northeastern and southeastern part of the Aravallies which run almost in the middle of the State from southeast to northeast. The latter groups of soils have more potential from the point of agricultural development in the State. These soils are widely termed as alluvial soils which is a general term to indicate the nontaxonomic group of soils that have parent material of alluvial origin, Riecken ¹⁷, Kelloog ⁸ has referred to the soils developed from the alluvium as classified under variety of world soil groups. In our country many of the alluvial soils have not yet been studied from the soil genesis point of view as a measure to classify the soils under taxonomic groups. Ray Chawdhary and Mukerji ¹⁵, concluded that the alluvial soil groups of our country are ill defined and the classification of these soils need more study. Basu ³ was able to distinguish the genetic characteristics of the soils of Deccan. Agrawal and Mukherji ¹⁾ established that distinct genetic soil types have come into expression under Gangetic alluvium. Agarwal ² has concluded about the three types of soils in the toposequence with precipitated calcium throughout, zone of calcium accumulation in the bottom of the profile and soils free of calcium, and suggests that the soils of Gangetic plain be called as derived from alluvium. A process of reclassifying the alluvial soil series into taxonomic groups is a common trend in the United States since the last two decades.
