Before revision: Advantages and limitations Advantages: the cost of the phytoremediation is lower than that of traditional processes both in situ and ex situ the possibility of the recovery and re-use of valuable metals (by companies specializing in " phyto mining ") it preserves the topsoil, maintaining the fertility of the soil Increase soil health, yield, and plant phytochemicals the use of plants also reduces erosion and metal leaching in the soil Limitations: phytoremediation is limited to the surface area and depth occupied by the roots.
