Szukana fraza: [Abstract = "Before the randomized experimental plots were established \(25m2 plots with plant density 2\/m2\) \?time\-zero\? soil samples were taken to determine initial levels of total \(aqua regia\) and bioavailable \(CaCl2 extraction\) concentration of Pb, Cd and Zn. After the growing season plant material was sampled during autumn \(October, green harvest\) and winter \(March, brown harvest\) to determine differences in heavy metal uptake. Results after the first growing season are presented, including the plot establishment success, biomass yield and heavy metal uptake."]
