Geo-Environmental Impact Assessment of Soil Quality Using the Physico-Chemical Parameters of Sankari Regions Salem District Tamil Nadu India

Abstract

Soil is one of the important components of the environment that affects the growth and development of plants. Soil testing is one of the chemical processes in which the suitability of essential nutrients is determined before sowing the crops so that the demand for remaining nutrients can be fulfilled artificially by applying fertilizer in the field. A physicochemical study of soil is based on various parameters like soil pH, Electrical Conductivity (EC), Aluminum (Al), Iron (Fe), Sodium (Na), Phosphorus (P), Potassium (K), Manganese (Mn), Calcium (Ca), and Magnesium (Mg). Ten representative samples were obtained and analyzed for their alkalinity content, pH, electrical conductivity, organic carbon, sodium, and potassium. Ten soil samples were collected at a depth of 0-20 cm and analyzed for soil that was neutral to slightly alkaline. Soil pH ranges from 7.16 to 8.34, electrical conductivity from 62 to 138, aluminum oxide from 0.4 to 0.26, iron oxide from 7.7 to 12.7, sodium oxide from 9 to 31, potassium oxide from 14 to 58, manganese oxide from 2.2 to 14, calcium oxide from 32 to 188, and magnesium oxide from 6.1 to 61. This information will help the farmers know the number of fertilizers to be added to the soil to increase production.
