Yes and with the Added risk of a few dock stems straining the plastic .
Could be worth considering using an additive especially if there isnt much leafy grass in it as well.
Also if you want it to persist dont cut it too tight ie leave a relatively long stubble. That in itself can provide a problem if bales are wrapped in situ as when they get dropped they might punture the odd place , well so would the dock stubble aswell i guess.
Wrapping at the stack would be better in that situation.
Thats my experience with anyway, makes brilliant stuff for sheep if your careful.
Good point about the stubbles being a PITA. I had a small 2.5ha area last year of short term ley that had a load of rape come in it that I didn't want the Fusion on!
I baled and then wrapped them myself, but brought the bales on the wrapper, 2 at a time to the headland, to try and stop the puncture effect on the field.
