• The soil microbiome regulates vital ecosystem functions ranging from primary production to soil carbon sequestration. Yet, we have only begun to understand the factors regulating the soil microbiome. While the importance of abiotic factors is increasingly recognized, the roles of trophic regulations in driving the structure and function of the soil microbiome remain less explored. Here, we review the current understanding of how and when microbial and top predators of the soil shape the community structure and function of the soil microbiome via both direct and indirect effects. We finally highlight that the structure and function of the soil microbiome depend on the interactive effects among predation, plant inputs, and abiotic variables present in the soil. Predators of the soil microbiome regulate microbial structure and functions via both preferential and nonpreferential feeding, with implications on their structure (e.g., diversity) and functions (e.g., nutrient mineralization).The trophic cascade effects on the soil microbiome is often masked due to intraguild predation and omnivory in the soil.Less is known about how microbiome predators influence the competition between soil bacteria and soil fungi.Global climate change can alter the trophic ecology of the soil microbiome by making it fungus-dominated, depending on soil moisture and resource availability.We propose that the interaction among microbiome predators, plant inputs, and abiotic resources could interactively determine the structure of the soil microbiome.
