Newspaper is biodegradable, so that when it is composted it turns into nutritious, mineral-rich topsoil. Even beginning gardeners can easily learn how to compost newspaper in order to produce the rich topsoil that organic gardeners refer to as "black gold."
Rip any quantity of old newspapers into strips, or run them through a paper shredder. Smaller pieces decompose faster.
Dig a hole in your back yard, 1 to 2 feet deep and 1 to 2 feet wide.
Cover the bottom of the hole, up to 4 inches deep, with newspaper and lightly spray it with water.
Add a layer of grass clippings and/or kitchen scraps to the top of your newspaper. This will hasten the newspaper's decomposition and provide an environment that bacteria, earthworms and microbes enjoy.
Cover the food and yard waste with a layer of organic garden soil. If there's room in the hole for another set of layers, just be sure that you keep layering in the same order: newspaper, followed by grass clippings and/or kitchen waste, then garden soil.
Leave the newspaper compost untouched for three months. After this you can sift the matter into a wheelbarrow for distribution in your garden.
