Had some bad experiences with poly in hay fields I rent. That stuff will destroy the bearings in a disc mower real quick, almost as quick as it will destroy the bearings in a lawnmower.
Poly is nice because the mice won't eat it but I cannot think of any other advantage and it becomes a real disadvantage when some 'idiot' (I use that term lightly) is too lazy to pick it up and dispose of it properly.
Poly will remain in state (on or in the ground) for eons.
Only thing I use it for here is row marker lines for the garden and in the fall, it gets tossed in the garbage.
Just look at the 'Plastic Tide' that is floating in the ocean if you want a reality check.
