Treatment abbreviations: LC—Litavka control soil without any additive, LCa—Litavka soil with lime, LP—Litavka soil with superphosphate, MC—Malín control soil without any additive, MCa—Malín soil with lime, and MP—Malín soil with superphosphate.
Differences between treatments and organs were evaluated by Kruskal-Wallis test. For each element, concentrations in organs within one treatment denoted with the same letter (a-b) and concentrations in treatments within one organ denoted with the same letter (A-C) were not significantly different.
