Background Microbiomes play vital roles in plant health and performance, and the
development of plant beneficial microbiomes can be steered by organic fertilizer inputs.
Especially well-studied are fertilizer-induced changes on bacteria and fungi and how
changes in these groups alter plant performance. However, impacts on protist communities,
including their trophic interactions within the microbiome and consequences on plant
performance remain largely unknown. Here, we tracked the entire microbiome, including …
