| Sumario: | In the micro plot experiment, the effect of varying light and medium soil contamination with heavy metals on their content in rye green fodder, serradella forage and barley, and the migration of Cd, Pb, Cu, and Zn in the soil profile was evaluated. Plants accumulated more heavy metals on light soil and soil with low organic matter content. Under the influence of increasing heavy metal contamination of soils, cadmium content increased more in fodder plants than lead content. After 14 years from the introduction of different rates of metals into the top layer (0–30 cm) of the two soils studied, a relatively large movement of heavy metals in the soil profile occurred. The amount of leached metals depends mainly on the rate of a given element. The more contaminated the soil, the heavier the metals that leached to lower genetic levels of soil. An increase in mobility was obtained alongside an increase in soil contamination with the heavy metals studied. By analyzing the mobility coefficients, they can be ranked in the following decreasing sequence: on light soils: Cd > Cu > Zn > Pb and on medium soils: Cd > Zn > Pb > Cu. |
