[QUOTE="Two Tone, post: 8126013, member: 44728"] Very interesting. Well done for trying. However there are a few golden rules that have been broken that have come back to haunt you [USER=681]@snarling bee[/USER] . We need a lot more information about what types of drill were used and when the crop was drilled. This is a 5th successive wheat crop on heavy land. I’d have thought with the build up of Blackgrass, ploughing was just about the only option to try and control it in this situation. Even then, I’m surprised you can get away without the need for an SU Pacifica type herbicide to control it. Min till doesn’t bury enough viable Blackgrass seed far enough below the surface to prevent it from growing. With regards the DD, was it a Tine or Disc drill? Whatever, to get any comparison, the DD section needed drilling at least a fortnight before any of the other sections. The reason being that you won’t have made any nutrients available that any type of cultivation would have. Therefore, the DD section needs that extra 2 weeks to get started. Also, contrary to what we believe with anything other than DD, being that delaying drilling will reduce the Blackgrass burden, with DD you can easily run into a situation whereby the wheat cannot compete against the Blackgrass enough, because it needs that earlier, extra time to be able to do so. Also, the DD drill needs to be one that gives the absolute minimal soil disturbance possible so as not to disturb and wake up any Blackgrass seed. As [USER=4612]@ajd132[/USER] rightly says high herbicides rates can easily damage DD’d crop, especially if put on in a stack in the Autumn, therefore stunting the crop even further. DD needs a completely different mindset compared to conventional, to be successful. Continuous wheat isn’t a good point to start and you need a decent rotation, probably not even using 2nd wheats. Successful DDing is a complicated balance of timing, drilling when the soils conditions are at their best and not hammering them with herbicides all in one go. Because Blackgrass seems to be worse in wheat, I’d want to use only 1st wheats after a break crop. Winter Barley, Especially the Hybrids are much better in a Blackgrass situation and far more ideally suited to a 2nd White straw crop. Especially on heavy land where Spring Barley will struggle. Whatever Break-crop you use needs to be one that controls Blackgrass well enough to prevent a Blackgrass situation from worsening. [/QUOTE]
