I read it that there's quite a bit of flexibility if you read @Brisel s link and you would probably be ok. Obviously you must include kale if its a 2 year mix. I would be tempted to buy a few other bits and pieces eg linseed, sunflowers etc to chuck in. Won't cost a lot and will make it 'look' a lot better.I need to put some AB9 in, I don’t want to spend much so I was thinking I have barley, wheat and OSR in the shed if I mix that up and providing none make up more than 70% of the mix will NE be happy? Obviously I won’t have a seed invoice but I would make a record and put it in the stewardship file.
Drilling isn't the issue, it's spraying and cultivating. I hand sow spring mixes and autumn goes in when the wheat is drilled. We're talking plots of less than an acre.Flail mower and then plough or rotavate? Glyphosate if required. To buy some kit to establish a few acres shouldn’t break the bank if contractor won’t come. Eg 3 furrow reversible rotavator and 3m drill.
