There has been little investigation of the ecological interactions between major organisms brought about by the application of wastewater biosolids to agricultural soil. This paper provides an overview of the possible effects of biosolids application on these ecosystems by using what is known about the ecology and diversity of microbial populations in soil and biosolids. Areas considered include interactions between indigenous and introduced bacterial populations, impacts of biosolids application on soil protozoa and the role of phages in bacterial population dynamics. These ecological processes are particularly relevant, for instance, to increase an understanding of the fundamental mechanisms responsible for inactivation of potentially infectious enteric microorganisms in biosolids‐amended agricultural soil.
