Analysing the Soil Nutrient and Physico-Chemical Characteristics of Soil in Bar-Mohra Khurd-Kalab Kalan Section of Pali District, Rajasthan, India

Minerals and organic matter are produced by weathering and breaking up the rock particles. The soil enriches with organic matter and minerals from aerial and subterranean parts. These are the main and important constituents of soils, which are influenced by biological activities. The role of the vegetation is relatively less in arid zones because of the scanty sparse canopy cover and the poor development of aerial parts but the root systems often exhibit exceptional development and have the greatest influence of the cracking of the rocks influencing soils formation processes. The parent rocks had definite relation with the soil nutrient and material which supports the vegetations. But in western Rajasthan the studies of relation between parent rock material and soil and further correlation of these aspects with different types of vegetations e.g. herbs, shrubs and trees supported by the soil is quite deficient. The present paper, therefore, highlights by the fact that the vegetations including herbs, shrubs and trees and most importantly the herbaceous vegetation vary from soil to soil depending upon minerals present in the soil and these minerals and derived from the parent rock materials. The present investigation may bridge this gap in the Aravalli hill ranges occurs in semi arid region. Therefore, the objective of this paper are to study the type of soils formed under the influence of parent rocks found in and around the Bar region of Delhi Supergroup. Another region is to investigate nutrient availability and different characteristics of soil for finding out its relation with the different type of vegetations it supports.
