I don’t know specifics, but I know in the San Joaquin Valley of California where I live, regular use of glyphosate on roundup-ready cotton has created a soil full of fusarium and pythium and no beneficial biology. That is over years of use, and I’m sure the problem continues to compound. Personally, I think glyphosate is pretty bad stuff from the research I’ve read. It’s just that it’s more chronic than acute. The damages compound generationally. The first generation you may see no real problems. The Institute for Responsible Technology has a great catalogue of the studies on it.
