Phytostabilization is a method that exploits plants to immobilize contaminants in soil or ground water using roots absorption, adsorption onto the surface of the roots, or formation of insoluble compounds as a result of interactions of contaminants with plant exudates in rhizosphere. This method reduces the mobility of contaminants and thus prevents their migration into the groundwater or into the air. Therefore, phytostabilization can be used for restoration of the vegetative cover at sites where the original vegetation disappeared due to a high content of metals in the soil. Plant species that are tolerant to high concentrations of metals can reduce migration of contaminants by wind erosion of exposed soil surfaces and at the same time they can reduce leaching of contaminants into the groundwater. The project is focused on increasing the production of energy crops (Sorghum sp.)and also to immobilize heavy metals in soils contaminated by industrial activities. The knowledge about energy crops cultivation on contaminated soils should provide new possibilities for solving problems with contamination of water and soil, which we are facing around the world.
