Mix your own: Mixing your own combination of N, P and K is the most economical way to use organic fertilizer, as well as the best way to meet specific conditions in the garden. Dont worry about getting the formula just right; its not so important with organics, since (with the exception of blood meal) you're not likely to hurt your plants or your soil by using too much.
Recipes: Mix these together thoroughly. You can keep the mix uncovered, the rock powders make the soybean meal unappetizing to the animals who would like the soybean meal by itself. However nitrogen does evaporate, so don't keep much uncovered for long.
These are my best attempts to digest the conflicting advice I have found in many sources. They are not guaranteed. If you have experience with other recipes, I would be interested to hear about them.
Commercial Products: If you dont want to bother making your own, there are premixed organic formulas available in several brand names; the most common are probably Espoma and North Country Organics.
