Potentially toxic elements (PTEs) adversely affect biological functions in soil including the activity of microbially mediated enzymes involved in nutrient transformation and cycling in soils. The effect of PTEs on microbial activity in soils depends on the bioavailability of PTEs. The toxicity of PTEs to soil microorganisms can be mitigated by reducing their bioavailability in soils using various organic and inorganic amendments, such as phosphate compounds, liming materials, manure, biosolids, and biochar. This chapter provides an overview of the immobilization of PTEs in soils using organic and inorganic amendments, and its impacts on the bioavailability of PTEs and the microbial response to the immobilization-induced reduction in the bioavailability of PTEs.
