The regional ecological and geographical analysis of the Cadmium Concentration Influence on the Agrolandscapes of Sumy Region
Abstract
The mechanism of accumulation of Cd compounds and the migration of its mobile forms in the soil are considered. The method of sampling soil and plants, as well as the method of morphometric research, was explained. The process of determining the content of cadmium in plants and soil was analyzed. The analysis of the experiment shows that high concentrations of Cd salts significantly inhibit all growth processes. This is manifested in growth retardation, color change, reduction in the number of leaves, occurrence of chlorosis and necrosis, which leads to a decrease in the accumulation of phytomass. With an increase in the amount of Cd, we observe suppression of plants and a sharp decrease in their height. A trend line is given based on the received data. The value of the reliability of the approximation is close to one and is R2=0.99, which indicates a close relationship between the increase in the concentration of cadmium in the soil and the decrease in the height of spring barley plants.
