Plant activities can play an important role in transfer and mobility of toxic elements. Using plants to restore the environment is one of the possible ways to fight with soil pollution. Plant systems are studied for estimation of changes of P availability at different equilibriums of heavy metals in soil. Our general aim was to investigate modern gentle remediation techniques to rehabilitate heavy metals (Pb, Cd and Zn) contaminated agricultural lands. Obtained results on P content in crops and P uptake by different plants in Kremikovtsi soil from different treatments have different values for the combination of crops and treatments. The soil from Pribram differs significantly to the soil from Kremikovtsi. Phosphorus assimilation depends on treatments, crop and the time of interaction of these two factors (growing period).
