Lots of inert matter and noxious weeds in feed wheat but to each their own. Come mid December you'll be asking where those giant looking turnip plants that cover your field came from and just remember the few $$$ you saved. Don't worry those wild turnips will be back next year also. This I have seen first hand on people land who used feed wheat vs seed wheat. 257's knowledge on this is well beyond mine so he can probably elaborate a little more.
