I am an Environmental Microbiologist who joined Monsanto in 2006. Since that time I have been in charge of conducting studies to evaluate plant-soil microorganism interactions and soil microbial processes as part of environmental risk assessments performed for all our biotech products. Before joining Monsanto I received my Ph.D. in Microbiology and Molecular Genetics from Michigan State University for research on the ecology of denitrifying bacteria in agricultural soils.

A: Glyphosate herbicide enables farmers to use no-till practices, which have been shown to benefit soil health and minimize greenhouse gas emissions from agricultural soils. Much of the benefit to soil health is mediated by microbial communities. Many studies have investigated the effect of glyphosate and Roundup Ready (RR) crops on these microbial communities, including rhizobia and fungi. First, I’ll address the findings on rhizobia, which are important members of the microbial soil... Continue Reading
Q: I have read from various sources that the combination of GMO plants and the patented chelatorherbicide glyphosate change the composition of soil, sometimes make it very difficult to sow and grow nongmo seeds ever again. Is this true?

A: Many claims have been made on the Internet that use of glyphosate-resistant (GR) crops and glyphosate can change the composition of soil because glyphosate is a strong chelator- a compound that can bind with metal ions- that will bind to micronutrients in soil. It is also claimed that this will increase the potential for disease to affect plants, or even cause new pathogenic bacteria to be present in the soil that can affect plant, animal and human health. These have all been used as reasons... Continue Reading
