Effect of rock phosphate on Zn and Fe bioavailability and accumulation by Salix smithiana in heavily contaminated soil

Popis výsledku v původním jazyce

S. smithiana accumulate Cd and Zn in aboveground biomass. In heavily contaminated soils willows can suffer from chlorosis. Chemophytostabilization is good measure for planting willows in such contaminated soil. We evaluated effect of rock phosphate on changes in Zn and Fe bioavailability and accumulation of these elements by willows together with the willows growth on heavily contaminated soil. Rock phosphate reduced plant-available Zn concentrations in soils resulting in significant decrease of Zn content in leaves. Fe contents in leaves significantly decreased as well, although the mobile portion of Fe in soil remained unchanged. Yield of aboveground biomass in rock phosphate treatment was not significantly different in comparison to the control. After the first vegetation period, we can conclude that reduction of Zn contents in willows after rock phosphate application did not lead to suppress of Fe deficiency and improvement of willow growth in heavily contaminated soil.
