A farm I bought has 15 acres of CRP on it.  I am going to crop it for a year and possibly put it back into a better CRP program.  Yesterday, we got it burnt off the best we could.  I have a Case 1250 planter and wondering if I am better off with a burn down of Round-Up and 24-D, then go no-till the beans or is there a better way to do it?  Thanks.
