Thanks for writing. There are three basic types of materials you'll need from compost: soil (which contains the microorganisms that break matter down into compost); carbon-rich materials (fallen leaves, sawdust, newspaper, etc.) that gets broken down into compost; and nitrogen-rich materials (rotted manure, fresh leaves, fresh grass clippings, most vegetable scraps etc.) to feed the organisms.
