From a practical point of view, the ability of plants to accumulate various heavy metals from the soil is one of the most available means to significantly reduce heavy metal contamination of agricultural land. By fertilizing plants with sewage sludge, we greatly improve soil quality and productivity, but at the same time we pollute it with heavy metals. By fertilizing with sewage sludge, we greatly improve the quality of the soil, but at the same time we pollute it with heavy metals. The field experiment is being conducted at the Vėžaičiai branch of LAMMC (Western Lithuania), the aim of which is to evaluate how particular annual and perennial plant species, growing naturally in acidic Albeluvisol, can purify the soil from individual heavy metals (Zn, Cr, Cd, Pb, Cu, Ni and Hg). Based on the data received, investigated plant species differ in their phytoremediation ability to accumulate heavy metals in their biomass. By producing high annual biomass yield, these species are able to accumulate significant amount of soil pollutants.
