Unless you have it analyzed, you can't, sorry. Seems like an awful lot of trouble, though, when packaged ferts are clearly labelled and inexpensive.

Iskhan, I've moved your post to the Vegetable Gardening forum. It may get wider viewership among "Do It Yourself" (DIY) people. I know that somewhere I read NPK values of basic ingredients the past couple of years, but can't remember right this minute. I'll search around for you.
