That's what I'm doing but not going quite that low. 1500 is plenty low enough I think it's a good enough amount that it isn't growing from the roots and should have enough leaves to photosynthesise and grow from. I have some left at 1800 to see what will happen. I expect it will just rot.My sheep will end up on a sacrifice field here on haylage once the paddocks are grazed out, so not too bothered about regrowth for winter grazing (if I got any), more about what sets up the place for next spring. There's a bit of dead stuff about. Best to take it down hard (1000-1200kgdm) and freshen it up?
