| Abstract:
The nutrient solution of hydroponically grown tomatoes (Lycopersicon esculentum) amended with olive mill waste water (OMW) suppress bacterial growth. In the same experiment, a promotion of beneficial microorganisms occurred. There are also some chemical properties of OMW supporting this hypothesis due to their high antimicrobial activity. We give evidence that the addition of OMW to hydroponic nutrient solutions provides an environment suppressing plant pathogens while favoring beneficials. | |
