greenhouse tomato soil Raw sequence reads
Reductive soil disinfestation (RSD) is an efficient and environmentally friendly practice for controlling soil-borne diseases, such as the bacterial wilt in tomatoes caused by Ralstonia solanacearum. The amendment of organic materials is an integral part of RSD, however, how the choice of organic materials affects the disinfestation of R. solanacearum remains poorly understood. Here, we collected nine plant-based organic materials with varying C:N ratio, and assessed their effectiveness in improving soil properties and removing R. solanacearum during RSD. In all, our results highlight the value of incorporating low C/N organic amendments with RSD to improve soil properties, suppress soil-borne disease, and advance the development of effective soil disinfestation strategies.
