We did some rolling a few years ago, we don't have GPS so the lad doing it got lost. A week later you couldn't see any difference either. Complete waste of diesel on the kind of land that gets black grass.I have been thinking about going down the rolling route, as in very wet or very dry years a full cultivation is counter productive, it's either that or a scratch cultivation, has anyone tried the old KV C tine harrows to do this? I could easily do disc and Xpress Vaddy but having gone to system disc I believe I could comfortably get away with 2 passes for establishment (I know this is in reply to ADJ and he is no till but the discussion is about a 2 pass system) it is getting a weed chit, cheaply, that is my challenge.
