Organic Compost for Tomatoes

I've been adding bonemeal to my compost for my tomatoes but am wondering whether anyone has any other good suggestions for what to add?
Thanks.

washed kelp, alfalfa meal......fish heads
just throwing some thoughts out there.

 

Thanks Jimmy. Washed kelp and alfalfa meal sound like good suggestions, will try those. I tried fish heads once for a fruit tree, but they didn't seem to help...
