Abstract
Soil reclamation is usually labor and cost intensive and thus in many cases uneconomical. The less expensive way to restore the quality of the ecosystem is to utilize microbes in so-called bioremediation. There are various ways in which flora can improve the soil ranging from trapping the pollutants in the rhizosphere, extracting them to upper parts of the plant or removing the volatile compounds through evaporation. The plants also impact the microbial community and help in recreating the natural balance. Overall, the positive effect on soil quality is a sum of many interactions that have the potential to completely restore degraded land, although it takes time and often requires additional supplementation of soil. The strategy should be tailored to use specific species to problematic pollutants to achieve the best results.
