John,
I had hunted high and low for the same thing. Was never able to find it in "quick" chart form. All the really good stuff I have found is aimed at commercial growers and talks more about lbs per acre, and of course, soil testing.
I did find this fairly comprehensive guide at one point.

It has a generic listing of crops and nutrient needs here.

This link might be of value as well.
