Using grains as fertilizer
I'd like to pose a question regarding using grains as fertilizers. I'm not really sure how to word it, so please bear with me if I'm awkward.
I mostly use coffee grounds to fertilize my lawn. I know that's not practical for everybody, but my approach is to take something that would have been waste and turn it into fertilizer (same reason I compost).
I've been reading a lot about how ethanol production has led to a global increase in grain prices (also increased water and petroleum use). I've also seen some concerns about clearing rain forests to make room for more grain production. These have made me question the wisdom of using grains as fertilizer.
I'm curious to hear other thoughts on this matter.
