"RoundUp specifically advertises that glyphosate doesn't break down over time but instead gets stuck in the soil (therefore not running off into a watershed)."
Glyphosate "adsorbs" or clings to soil particles where it is acted on by soil organisms and broken down, usually in a short time of days or a few weeks. The relevant context is that by adsorbing and sticking to particles the glyphosate doesn't tend to drain into lower soil layers but stays where there is more soil activity by bacteria, etc. Depends on conditions, of course.
