I've been searching around for a while now, and although I find scattered information regarding the nutrients contained in certain compost items, I have been unable to find a sort of exhaustive listing of the nutrient profile for common kitchen/yard/farm waste. I am a lover of references and would find it extremely helpful if there were some book or website that has such a listing. If not, wouldn't it be nice to pool all of our information and knowledge to come up with a list? Someone mentioned putting rusty nails in the soil to add needed iron, which is exactly what my raspberries need. So I went into the garage and found some old nails sitting around and have pushed them into the ground around a raspberry plant to see if it works. I am attempting to reduce my dependence on external fertilizers as much as possible, and if I knew something like banana peels can be used to at "this" specific content to the soil around "that" specific plant, it would seem a more efficient use of my kitchen waste than just throwing it all in the compost pile. I think it would be important to differentiate between nutrients found in the waste, and nutrients that actually made it into the soil, and any conversion of nutrients when the waste decomposed.
