Not long ago, I was reading a PDF report on organics written by a couple of science dudes, and what they said was pretty amazing. According to them, by just using nothing but kelp meal and alfalfa meal, all 83 macro and micro nutrients needed for healthy plant growth will be available to your plants. I forgot to save the PDF file, so I can't post the article for you, but here are a couple of other articles that list all the macro and micronutrients of both items. Kelp and Alfalfa meal are pretty phenomenal stuff.

Also, here is an excellent file found on an old AFN thread that lists all the nutrients found in various manures and organic amendments. It's very complete and an excellent reference.
