Does spring rolling of winter cereals germinate blackgrass in zero till clay? (There is good ground cover from residue)

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.

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.

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.

In 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.
Chicken muck already under it

Should also save the need for early growth reg perhaps?

Again not DD but I have quite an area of wheat that has not been rolled. Normally I wouldnt worry but now with more rotational ploughing I am getting more large flints on the surface so I am going to have to spring roll so as not to kill my combine. I am worried that if I go too early I will damage the pre em barrier and get a black grass flush. When should I roll assuming good weather conditions. I will finish pre/peri ems this week.

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.
Recreational CCC?

Flat corn gets a big thumbs down.
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.

The old "cure" for thinner stands of wheat was to chuck a bit of AN on; roll it a couple of times; leave a week then a bucket full of mineral and a splash of moddus.

I think we like to roll as it leaves it all stripey more than anything else. Several past agronomists have had kittens watching me do it, but I've rolled spring barley three times post emergence with no problems.

All my wheat is after oats and not ploughed, so consequently will be looking like it's gasping for fert come spring.
