I'll agree with Ray C's observation. Since the first years we've planted plots - I'd only consider Buckwheat as a "soil rebuilder". The deer might end up liking it a couple weeks / year - but it cannot compare to clover, soybeans or other long term food plots. BUT the soil has to be good first.

So - Buckwheat can be a great 1st plot on newley prepared ground. It Definitely helps add organic matter and pull up nutrients.
