Study of Physico-chemical Properties in Industrial Areas of Chambal Region Soil

Abstract

Background: Soil is a crucial and remarkable component of the terrestrial ecosystems. The objective of this study is to analyze macronutrients and micronutrients in order to understand the suitability of soil for cultivation of crops in the selected sites. In the present study the physicochemical analysis was carried out by analyzing the parameters i.e. pH, organic carbon and potassium etc. Methods: Four soil samples were collected in 2017-2018 during the winter season at different locations in industrial areas of the Chambal region and compared with the standard value of soil quality. The micronutrients Fe, Cu, Mn and Zn were determined by using atomic absorption spectrophotometer. Result: Organic carbon was observed in a range between 0.51 to 0.55%. The soil pH was observed neutral to slightly alkaline in nature (7.2-7.6). All the parameters were under the permissible limit of soil quality standard except the phosphorus which was found to be less than minimum requirement ( less than 28 kg ha-1). Pearson’s correlation matrix result demonstrated that several physicochemical characteristics of soil were having a positive association, particularly soil pH, were correlated with EC and sand content. Organic matter and organic carbon had positive and significant correlation with nitrogen, phosphorus, potassium and iron. Organic matter and fertility of soil was significantly correlated. Therefore, the proper study of soil provided the information about its fertility and crop productivity.
