I have been no-tilling plus using cover crops for 10 years. I now have over 3.1 organic matter in one farm, 4.0 on another and 5 on a third farm just out of CRP. This year on some corn fields, the weed control was bad. I have heard you should increase herbicide rates when your organic matter gets above 3. Has anybody experienced this?

I understand your thinking behind the increasing rates thing, I've been there. I have one muck farm that has organic matters as high as 50% in some areas. Maybe I should call it a peat bog. lol I use standard rates there, you just have to be diligent about scouting for outbreaks and reapply as needed. Is reapplying the same as applying a higher rate? No. Think in terms of crop injury,,, that may occur with higher rates. I hope this is helpful.
