Persistence of plant-mediated microbial soil legacy effects in soil and inside roots [PDF]

open access: yes, 2021
Plant-soil feedbacks are shaped by microbial legacies that plants leave in the soil. We tested the persistence of these legacies after subsequent colonization by the same or other plant species using 6 typical grassland plant species.
