Chemical weathering breaks up the physically disintegrated rock fragments and organic matter. The process of chemical weathering in arid regions is not fast because of water deficiency. The present study was undertaken on soil contamination in Lawacha-Mohra Khurd section of Pali district, Rajasthan. The aim of the study was investigate the pollution of soil, which is a source of danger to the human and animal kingdom. The polluted soil also damages the nutrient availability along with quality of soil is also diminishing. Various inorganic soil samples were collected from different locations. In laboratory these samples of soil were analyzed to measure various chemical parameters by standard methods such as pH, electrical conductivity and % of organic carbon (OC) were determined. During the course of the study periods, fluctuation in the various parameters was observed due to unequal distribution of different minerals constituents present in the soil. These constituents in soil are produced by breaking up the rock particles and enriching with organic matter from aerial and subterranean parts, also influenced by biological activities. The role of the root systems often very important because it exhibit exceptional development and have the greatest influence of the fracturing in the rock formations producing soils rather than vegetation. Therefore, the objective of this paper is to study the different characteristics of soils around Lawacha-Mohra Khurd region of Delhi Super group and to investigate nutrient availability in different types of soil for finding out its relation with the different type of vegetation it supports.
