Ease of establishment, it can be broadcast, grain drill, no-till in the spring or fall.
Stiff competition with minimal management, and i mean grazing management or fertilizer, it's just tough. There are crop fields here that they spray glyphosate on every year at least once... By next spring there will be a large amount of volunteer fescue, generally growing quite well from all the excess nitrogen from the previous crop.
It holds up equipment and cattle very well in the winter time and if they do pug, theres a pretty good chance it'll be back.. Only place I have problems is my portable salt and mineral feeders and I now just take them away when it gets to muddy.
And most importantly for me and my operation.
In the words of Jim Gerrish, "there are 3 reasons to have fescue, January, February, and March"
And there they are, Jan. Feb. & March. Better than any hay I bought this year.
However it is a 2 headed beast and the other side has been discussed.
