Answer
Gary, corn meal is probably the safest and most inexpensive organic fertilizer for grass. But there are also commercial products that are more balanced and designed specifically for lawns.

My advice is to review a couple of organic merchants that specialize in this type of product. My two favorites are Gardens Alive and Planet Natural. Just be advised that organic fertilizers are much more expensive than synthetically processed fertilizers. However, if your area is small, it is well worth the investment.
