Abstract

Soil is an important ecosystem component; it serves as a habitat for many microscopic organisms that play an important role in the ecosystem's maintenance and crops grown in soil. Unfortunately, human activities have adversely affected not only the environment but also the soil health. Soil has been contaminated with heavy metals hydrocarbons and hydrocarbon-based products that are affecting soil health and the growth of plants. In this review two methods of heavy metal remediation are discussed; one is the role of plant growth-promoting bacteria (PGPB) in the enhancement of phytoremediation and the other is composting. PGPB help plants to grow better by providing them with nutrients, in turn, these plants play a role in the phytoremediation of heavy metals. In composting, targeted pollutants like petroleum products, pesticides, and chlorophenols are decayed by the action of microorganisms present. The use of PGPB provides an efficient and pollution free solution for the removal of heavy metals from soil reviving its properties while composting results in the mineralization of different hydrocarbons and the minerals also become the part of soil increasing its health. Likewise, these techniques are helpful in the removal of harmful organic and inorganic pollutants from soil and reviving it.
