Effect of sulfur-perlite containing waste on clover productivity and heavy metal translocation (Cd, Pb, Zn)

Abstract

The results of field experiments conducted in order to determine heavy metals (Cd, Pb, Zn) translocation in the
system of sierozem and sulfur-perlite containing waste - a plant, as well as their impact on clover yield are presented in the
article. Experimentally obtained results indicate that sulfur-perlite containing waste has a sorbing property in relation to heavy
metals, it has fertilizing and ameliorative property. The dependence of clover yield on the nature and quantitative content of
heavy metals (HM) in a soil system has been revealed. Except that, it is not recommended to use the first hay cutting of the top
clover grown in the soil which is technogenic contaminated with heavy metals since content of all three studied heavy metals in
a plant much more exceeded their maximum allowable concentrations (MAC). The second and third clover cuttings contained
HM (Cd, Zn) in concentrations not exceeding the MAC, therefore they can be used as fodder. Translocation process slowdown
in the case of lead has not been established. Pb content in a plant (clover) weight obtained by the second and third cuttings
exceeds the MAC values; therefore a clover grown in the soil contaminated with lead cannot be used for animal nutrition, for
food and medical purposes
