Can I Moldboard Plow Fields To Eliminate Weeds?

Question: I didn’t have much of a corn crop this year, and weeds turned some of my fields into a jungle. Would it be ok to moldboard plow those fields?

Answer: That’s a pretty radical option, but it may help bury seed that’s present so it doesn’t sprout and interfere with next year’s crop. For plowing to be effective, you must understand each weed species that’s out there because some weed seeds need to be buried longer than others. I’d avoid plowing if you can, but if your weed seed bank is completely out-of-control, then that might be a good option.
