NOT ALL GOOD BACTERIA GET ALONG
Just as the beneficial bacteria living in yogurt and sauerkraut are good for your gut, tiny organisms living in the soil help plants and intense research is underway on natural “probiotic” soil treatments containing living microorganisms. Developers of these products have been including multiple species of beneficial bacteria in their formulations, aiming to boost crop growth and yield. But new research from the University of Delaware suggests these selections must be made very carefully, because not all good bacteria get along.
