I've trialled them over the last few years both on our own and other peoples farms and I have to say I haven't seen or heard of any major advantages in black oats over common or garden ones just a lot more expensive !

Only problem with oats is that they suppress your cereal crop as much as your black-grass due to a combination of allelopathy, N lock-up and phytotoxic acids generated when the oat residues break down. Less of a problem for beans.

whilst it is theoretically possible I think the answer to that is not always ....

Our beans behind your No1 mix are fine. My worry is that not always isn't enough of a guarantee for cereals, unless you glyphosate well beforehand, and the received wisdom on that seems to be at least a month if not six weeks.

.... because you don't want to spend the extra money on Black oats?
I was talking to a company a few weeks ago and they say it most definitely works. Black oat produces large amounts of biomass and maintains a narrow carbon to nitrogen ration therefore cycles nitrogen very well.
It breaks disease cycles in wheat and is resistant to some nematodes and has exceptional allelopathic activity for weed control.

that I agree with too ...but at nearly £2000 a tonne it ought to do a good job !.... because you don't want to spend the extra money on Black oats?

and a lot of those same things can be applied to ordinary oats too

Some may be that price but some are almost half.

I think to get the best benefit of blackoats you need to sow early.

But not to early Will as it could be more susceptible to winter kill and lodging.
Oats/Vetch seem to be a very popular choice for this year.

....and at least eight weeks to be out of danger, but to be fair it is all about the weather ( temp and rain ) after drilling that makes the difference.

I got more biomass with black oats FWIW. I didnt have a problem sowing spring oats behind them having sprayed off 5 weeks before. They were part of a mix.

I visited a guy in Argentina who is the arabale manager on a large dairy farm. He stopped growing black oats because they looked so good the got silaged. Now he just uses normal oats.
However I've never seen a lot of benefit from them here. I would say that if the higher seed rate for normal oats isn't a problem, then use them.

I've got a small area of oats / beans/ peas/ sunflower cover crop beside the road Adam, should look a right mess soon! It's not fancy just what I had lying around.

We spend a lot of money controlling wild oats. Any chance of a 'wild black oat' problem or are you always planning to spray off before seeds are produced?

Was thinking of a cheap cover crop of home saved OSR and home saved oats.
