UPTAKE OF SOIL-APPLIED CADMIUM AND ITS DISTRIBUTION IN RADISHES

Abstract

Various amounts of cadmium chloride were added to unlimed and limed Hjorth soil in a growth-chamber experiment to study cadmium uptake by radish plants. The plants accumulated more cadmium in the tops than in the root portion. Concentrations in both tops and roots increased progressively as more cadmium was added to the soil. When lime was also applied, plant concentrations were increased to a lesser degree than for unlimed soil. Both independent variables included in equations to predict plant cadmium content from added cadmium and added lime contributed significantly to the multiple regression.
