How long must one wait for glyphosate to denature in the soil before planting ?

Simon.

Half-life of glyphosate in soil varies widely depending on individual
conditions. 40 days is an average, but as short as 2 and as long as
140. Note that half-life isn't the same as persistence. Detectable
levels can persist for several half-lives (a bit like radioactivity,
or indeed any half-life). See http://tinyurl.com/jzf9396


Which doesn't actually answer his question....
