A comparative study on the physico-chemical parameters of the soils of Chitradurga district, Karnataka

The physico-chemical study of soil is based on various parameters like color, pH, Electrical Conductivity (EC) and status of available total primary macronutrients (N+P+K), status of Sulphur (S), Organic Carbon (OC) and total micro-nutrients (Cu+Fe+Mn+Zn). Soil fertility identification of a region plays an important role in the context of sustainable agricultural production. The proper proportions of primary macronutrients, micronutrients present in the soil represents the fertility status which helps to control the yield of crops. The chitradurga district of Karnataka was selected for the study. The soil samples(depth 0-15cm) were collected randomly in all the taluks of chithradurga district and compared for their physico-chemical properties. These results help agronomists, agriculture engineers and farmers for finding the problems related to soil, nature and nutrient status and improve the sustainable agricultural production.
