Developing disease suppressive soils is a fascinating area of research, with the potential to completely change how we manage plant diseases in the near future. In this presentation, you will learn more about the factors which allow soils to suppress potential pathogens, how we are better able to manage these influences in the field, and produce soils which can greatly reduce or even eliminate plant infection by a broad range of soil-borne pathogenic organisms.
