For corn I think you might want extra N? I do use organic fertilizer for corn. Last year, I used Alaska fish pellets and Dr. earth 4-4-4. This year, although my corn has been doing exceptionally well so far with just the not-quite finished compost full of active worms and soaked alfalfa pellets at initial planting, I just side dressed with Dr. Earth veg. (5-7-3) today -- which actually does NOT have highest N in the three key nutes, but I was persuaded that this is better than what I was *going* to try, which was organic lawn fertilizer.
If I had an easy access to them, I might consider rabbit manure -- have been hearing good things. (I've been saying this since last year without forward progress, but I did find a local rabbit rescue org. about 1/2 hr away....)
... I have to admit though -- I'm still experimenting with growing corn. What do other organic gardener's use for their corn, I wonder?
