“…Several approaches such as incineration, excavation, and the use of chemicals have been employed to clean up polluted soils but these methods are too expensive and do not provide total cure as some just shifted the contamination from one site to another (4). Most of the times, they also result in production of secondary pollutants, which incur another negative impacts on the environment (5).…”

Soils are polluted by both organic and inorganic substances. Plants growing in polluted soils suffer damages such as leaf rolls, chlorosis, growth inhibition, root tips browning, and death of plant. Soil pollutants such as hydrocarbon and heavy metals are absorbed by crops and such ends up being consumed by human posing health risk like cancer and respiratory abnormally. Conventional methods of remediation such as chemical and physical methods are very expensive and not sustainable. Excavation, which is a type of physical method, merely shifts the pollutant from one site to another. Bioremediation is a biological method of reclaiming polluted soils. Bioremediation is less expensive and more sustainable and safer when compared to the conventional methods of reclamation of polluted environment. This biological method of remediation is an extremely attractive, important, and productive alternative for cleaning, debugging, managing, and rehabilitating and consequently ameliorating contaminated environments via judicious utilization of microbial activities. The rate, at which the waste substances are degraded, is usually dictated by competitiveness among biological agents, sub-optimal supply of essential nutrients, unconducive abiotic conditions (in forms of temperature, aeration, pH, and moisture), and constrained pollutant’s bioavailability. Bioremediation is often effective only under conducive environmental conditions favorable for microbial growth and development. It has been successfully used at various parts of the world. Based on the significance of bioremediation in enhancing the reclamation of polluted environments by decontaminating and degrading heavy metals and xenobiotics, more focused researches would be needed so as to improve contaminated environments in much safer ways and conditions through bioremediation techniques. This research discussed the various types and methods of bioremediation. The mechanisms of actions and strategies of microorganisms in bioremediation were well expatiated. The interaction between bioremediators and the mineral particles in the soil environment was explained.

“…They can Muratova et al (2005) therefore be used in biological control against plant pathogens (Sukweenadhia et al 2015) against weed pest (Biological herbicides) (Babalola et al 2007) and insect pest (Saharan and Nehra 2011). Microbial inoculants can also be used in phytoremediation of polluted soils (Alori and Fawole 2012;Alori 2015). Waterlogged, compacted, desiccated wind and rain eroded soil are remediated through microbial inoculation.…”

“…Phytoremediation of contaminated soil assisted by microbial inoculants enhance plant growth through: Production of plant growth hormones such as indole acetic acid and cytokinins, essential nutrients released by nitrogen fixers' siderophore producers and phosphorus solubilizer and suppression of the production of stress producing ethylene and hence have the potential to aid phytoremediation. Microbial inoculants are capable of remediating both organic and inorganic soil contaminants (Alori 2015). Some plants and associated microbial inoculants in phytoremediation of some soil inoculants are shown in Table 9.2.…”

Agricultural soil pollution refers to its accumulation of heavy metals and related compounds which could be from natural or anthropogenic sources. This threatens food quality, food security, and environmental health. The traditional physico-chemical technologies soil washing used for soil remediation render the land useless as a medium for plant growth, as they remove all biological activities. Others are labor-intensive and have high maintenance cost. Phytoremediation, sustainable and cheaper in situ remediation techniques was therefore considered. However, plants do not have the capability to degrade many soil pollutants especially the organic pollutant. It is therefore imperative to take advantage of the degrading ability of soil microorganisms. This chapter therefore focuses on phytoremediation techniques augmented by microbial inoculants.
