Interesting article. This part in particular. I had no idea that it could reactivate and adversely affect the crops you were trying to help in the first place.

We do know that even though it’s immobilized rapidly in most soils it can then be reactivated or desorbed and reactivated to damage future crops.
ACRES U.S.A. What must happen to reactivate it?
HUBER. One of the things that’s recently
been shown to do this is to apply phosphorus fertilizer on the crop. From a nutritional standpoint, it can actually desorb the glyphosate so that it’s again reactivated as an active chemical for plant uptake and damage.
ACRES U.S.A. Has this been demonstrated
by researchers to impact the crops when it’s desorbed?
HUBER. Yes. That can be quite damaging
to the crop and actually limit uptake of nutrients required by the crop as much as 60 to 70 percent, and that’s pretty much across the board.
