Miranda Hart, who teaches biology at UBC’s Okanagan campus, says despite a decades-long practice, there could be environmental consequences of adding bio-fertilizers into soil. It’s common practice for farmers to use bio-fertilizers as a method to improve crop production. These added microorganisms will live in the soil, creating a natural and healthy growing environment.
However, after a multi-year study on four different crop fields, Hart says the inoculants may not be doing much for the soil. The study, which involved researchers from Agriculture and Agri-Food Canada, was published recently in Science of The Total Environment.
