Abstract
Distribution of cadmium, pH KCl , and organic carbon content in the soil over a 29-ha field was evaluated. Cadmium concentrations were found mostly within the interval 0.17–1.27 ppm, with increasing trend towards one edge of the field. Cadmium concentrations were correlated with pH and organic carbon content. A one-hectare section of the original area was selected to analyze spatial variability of cadmium, pH and organic carbon content using geostatistical techniques. Cadmium concentrations were found to be spatially dependent and anisotropic, whereas pH levels did not reveal space dependence. Similar spatial behaviour of cadmium and organic carbon was observed. Linear correlation analysis at the one-hectare section revealed strong correlation between organic carbon and Cd, whereas no coincidence between Cd and pH was found. Extensive application of a cadmium-contaminated sludge in the past is suggested as a possible cause of this phenomenon.
