In a two-year microplot experiment conducted on sandy and loess soils contaminated with Cd and Pb, the response of energy willow to these metals has been analyzed as well as the results of soil reclamation using two rates of peat. Differences have been observed between the soils, both in terms of the response of plants to pollutants and the effect of the applied peat. Contamination of sandy soil with Cd and Pb have led to complete necrosis of plants, whereas the yield of willow plants obtained on loess was comparable to the control. The application of peat to sandy soil limited the transport of metals by willow plants to aerial parts, restoring the intensity of photosynthesis to a comparable level, as in the control treatment.
