How GMOs and Glyphosate Impact Soil Biology

Robert Kremer, Phd., co-author of the book Principles in Weed Management, is a certified soil scientist and professor of Soil Microbiology at the University of Missouri. He recently retired from the United States Department of Agriculture (USDA), where he worked as a microbiologist for 32 years. He's conducted research since 1997 on genetically engineered (GE) crops, and in this interview he reveals how GE crops and glyphosate impact soil ecology and biology. We often think of glyphosate as just another herbicide being applied topically, but it's important to realize that one of the properties of glyphosate is that when it enters a plant, it becomes systemic, and cannot be washed off like many other herbicides. Making matters even worse, glyphosate formulations such as Roundup are synergistically even more toxic than glyphosate itself.
