Suppressive compost: snake oil remedies or achievable goal?

In recent decades, many researchers have aimed to create suppressive composts and determine the factors that distinguish them from non-suppressive ones. The research conducted by A. Logo, B. Boppré, J. Fuchs, M. Maurhofer, et al. (Appl Environ Microbiol 91:e01100-25, 2025, https://doi.org/10.1128/aem.01100-25) represents a significant advancement in understanding the microbiological bases of this phenomenon, as it evaluates the suppressiveness of 37 composts across three different pathosystems. The authors successfully identified certain bacterial and fungal taxa that could potentially act as indicators of specific disease suppressiveness.
