Přispět k objasnění zákonitostí interakce systému půda-půdní roztok-rostlina (krmivo, potravina) se zvl. zřetelem k dominantní úloze labilních forem půdního C org. Charakterizovat status sledovaného území z aspektu obsahu (potenciálně) rizikových prvků. (cs)
This project is focused on potentially risk elements (namely Co, Cu, I, Mo, Se and Zn) transport problem from soil environment to plant tissue and on influence of labile (active) soil organic matter fractions on these processes. In five partial parts is evaluated a loading of experimental plots with above mentioned elements, the impact of pratotechnic and agrotechnic management manners and the influence of some selected crops on elements’ bioavailability. Also character of interaction between these elements and some soil organic carbon fractions is assessed. Solution of this project contributes to ecological remediation of the important part of agricultural landscape ecosystem. (en)
