Ozone impact on soil bacterial and fungal microbiota

Ozone is a volatile compound with strong oxidizing and disinfectant properties, and its use in crops such as grapevines has been proposed as an alternative to abusive pesticide application. While its disinfectant efficacy has been demonstrated in barrels and grape berries, and its effects on vine physiology have been studied, its impact on soil microbiota remains poorly understood despite its relevance to the agroecosystem. This two-year vineyard study assessed the impact of irrigation with ozonated water on soil bacterial and fungal microbiota using metataxonomic approaches.
