Conditioning the soil microbiome through plant–soil feedbacks suppresses an aboveground insect pest

Summary Soils and their microbiomes are now recognized as key components of plant health, but how to steer those microbiomes to obtain their beneficial functions is still unknown. Here, we assess whether plant–soil feedbacks can be applied in a crop system to shape soil microbiomes that suppress herbivorous insects in above‐ground tissues. We used four grass and four forb species to condition living soil. Then we inoculated those soil...
