The challenge of reducing metal phytotoxicity insoils affected by historical nickel-copper smelting operations in the Kola Peninsula, Russia

The topic of vegetative cover rehabilitation industrial barrens sites has a worldwide significance, especially given the potential polluted soils themselves to be “secondary pollution sources.” goal this study was determine effect peat addition lime + vermiculite-lizardite combined amendment on plant growth in from vicinity Ni/Cu smelter Kola Peninsula, Russia. Given complexity and time-consuming nature field studies, we decided test selected amendments under laboratory conditions first. Surface horizons two Spodosols (0-20 cm) were collected smelter. Lolium perenne cultivated pots for 21 days controlled conditions. difference with without not substantial. In other words, did improve efficacy promoting growth. Therefore, challenge reducing ryegrass exposure soil metals remained unsolved.
