Nutrient status of Dhanbad district soils
Dr. Adarsh Kumar Srivastava, Mahesh Chandra Jerai and Dr. JK Lal
Soil fertility is a complex quality of soils that is closest to plant nutrient management. Soil fertility is an aspect of the soil-plant relationship. Fertility status of the soils is primarily and importantly dependent upon both the macro and micronutrient reserve of that soil. Continued removal of nutrients by crops, with little or no replacement will increase the nutrient stress in plants and ultimately lowers the productivity. Soil test based nutrient management has emerged as a key issue in efforts to increase agricultural productivity and production since optimal use of nutrients, based on soil analysis can improve crop productivity and minimize wastage of these nutrients, thus minimizing impact on environmental leading to bias through optimal production. Deficiencies of primary, secondary and micronutrients have been observed in intensive cultivated areas. This Physio-Chemical study of soil is based on various parameter like pH, Electrical Conductivity(EC),Total Organic Carbon, Available Nitrogen (N), Available Phosphorus (P2O5) and available Potassium (K2O), Sulphur (S), Zinc (Zn), Boron (B) and Iron (Fe).
