The Gila is definitely a special place. I was there way back in 1970 while I was in the Army at Fort Bliss and have been back two more times in the last ten years after mulies with no success, but saw deer both times.
Let me start off by saying I am not a farmer.
I am a deer hunter and I do own a tractor and have all of the equipment - but that does not make you a farmer any more than standing in the garage makes you a car - well, you get the picture!
Having said that - and with most of my ineptitude fairly well hidden - I do think that buckwheat is one of the most under rated cover crops out there.
I say cover crop because I see mixed results as it relates to the deer eating the plants.
