Are you serious? I can't imagine you are, as where I live natural fertilizer is a huge industry on it's own. There are also huge benefits from natural fertilizer as opposed to using synthetic. You can also put GMO's into play, which can increase the yield even further. Honestly, the true goal is to not have a need for synthetic fertilizers, a lot of farmers would say that.
I don't really care about the battery crap, as of now that's somewhat true. We can't sustain much off renewable resources yet, though I have faith we will.
