My no til crops

Did you get many rooks on these? What do you think caused the lower establishment here? Our one field of zero tilled winter beans is a lot patchier than the fields we went over once with the Terrastar. Some bits are OK, but there are quite big patches that aren't. Seed didn't really go in deep enough and straw was stuffed in the slot which did close -- this made it easier for the rooks / slugs to get at them. Even had to pellet this field.
I don't really know why the establishment is worse. There weren't any rooks or slugs and the slots were closed just as well. It's as if the oats did produce an alleopathic exudate that even effected the non cereals as well as cereals or just purely that the cover took the moisture at seeding depth.
The only other thing is wether the high rate of glypho was somehow translocated down to the cc roots and picked up by the new seedlings??

I might be wrong, but I thought the allelopathic effects from grasses affect any emerging seedlings. Whereas established broadleaved species can be killed without creating the problems for emerging grasses or broadleaves.

A very interesting thread, we've had similar issues issues.
No oats in the CC, some volunteer wheat, linseed drilled on the green and its struggled to get going. To the point I thought it had failed.
Slug pellets applied, flea beetle sprayed etc. But I can't help feeling it should have out grown any pests. There weren't massive numbers of either.
Talking to our agronomist we did wonder wether it mate have taken up some glyph exuded from the CC roots.
I think it was @mikep had a theory on this.
WW and W beans drilled on the green always seem to be ok.

I've got a patch of rye grass in a field I sprayed off a good few weeks ago, the rest drilled was with millet 'on the green'. It'll be interesting to see how it compares.
The only other thing with our linseed was we used Callist pre em. We did wonder wether this may have been washed on to the seedling. Just another unknown.

We had the effect drilling into spring barley stubble which was untouched, and that wouldn't have had the root translocation effect. That's not to say that wasn't the reason in your case though. Don't know if you remember that article that @martian linked to in the 'Fate of Pesticides in the Soil' thread? That went into quite a bit of depth about that effect.

Very interesting article on this very subject by Matt Hagny in issue 8-3 of Leading Edge, which Silliam W kindly posted up a while ago. Can't work out how to make it easier for you to access.

No. I've only got a micro granule applicator on the drill but just spun Fert on top after drilling.

Well I don't know how much it would have effected your situation, but this picture presents what happened here when I shut fert off on the drill to fill in a narrow gap (spring wheat, drilled right after each other). I have same situation in spring barley where I shut fert off in a strip. This would probably be noticeable in a tilled field as well, but no-till may have enhanced the effect with possible nutrient lock-up.
