My guys said it smelled like a dead mouse. Not sure what's up with that, but when we opened the bag, it stank up our entire office. I'm doing some more checking cuz I haven't given up on "natural" organics yet.
Well, if it smells bad what was in the fertilizer? If fish was an ingredient it will have an odor. It's such a general question it's hard to give a concrete answer.
As far as organic corn and soybeans, with GMO's you probably won't get true organic of either anymore.
