Years ago LSU came out with a mix of worm castings, cricket castings, crawfish shells and several other things. It was supposed to be the shiznit from what I read. Never tried any but I used to love using crawfish shells and worm castings in my garden. I had tomato plants that were in 6 ft cages and then laid over and ran another probably 12 feet along the ground....I also put a small bream or catfish in the bottom of every planting hole. You can't go wrong with organics.
