Does spring rolling of winter cereals germinate blackgrass in zero till clay? (There is good ground cover from residue)
It’s all on disc drilled land I’m considering doing it, there are no clods. But I am wary still. There is very minimal amounts of blackgrass in the historically bad areas. Easily rougable levels.Depends.
If you have a lot of clods they get broken down and release their deadly cargo. Or the soil can be crumbled up and let some light in on the little blighters.
In theory the crop will be stimulated and out run it all anyway. I would be wary of it. If you have bad patches of it appear in crop I would seriously consider cutting your losses and roundupping those areas.
Chicken muck already under itIn the circumstances described I would probably do it but I would evaluate the crop in spring to see if it needed it. Certainly not something I would plan to do routinely. Better to give the soil some extra zing by improving fertility with dung etc.
Should also save the need for early growth reg perhaps?Not no till but...
We spring roll a lot of wheat, and yes we do get a few extra weeds although usually blws. Given a normal year we get plenty of surface cracking and bg from there, I don't really worry about it. All rogued anywsy.

fair point, i didnt mean leave it all out just the early ccc. althought it may get broadway so that will do that job anyway.Not really. Certainly thickens it up. But I'm not sure anyone would convince me to leave the pgr our given the digestate, grass and feet we put on.
Recreational insecticide = nooo.
Flat corn gets a big thumbs down.
