How to Make Compost for Mulching

Prepare an area for a compost pile by removing grass and weeds. You can also use a homemade or commercial structure such as a compost bin or barrel, which contains the compost and keeps the area neat. Compost bins are available in a range of styles and sizes.

Pile 3 to 4 inches of organic yard waste on the soil, or in the bottom of the bin or barrel. Use coarse yard waste such as chopped brush, which promotes air circulation at the bottom of the pile.

Place 6 to 8 inches of damp, or "green," organic waste on top of the coarse waste. Damp organic waste may consist of grass clippings or moist leaves. You can also add kitchen waste such as eggshells, fruit and vegetable waste or coffee grounds. Avoid dairy products, whole eggs, grease, bones and meat, which may attract vermin and insects.

Spread about 1 inch of soil on top of the damp organic waste. Soil contributes organic microorganisms, which assist in the composting process. Up to 10 percent of this layer can consist of sawdust.

Spread 2 to 3 inches of well-rotted animal waste such as cow manure over the top of the soil layer. Animal waste contributes nitrogen to the composting process.

Sprinkle a handful of rock phosphate or lime over the top to prevent the manure from becoming too acidic.

Moisten the pile if the manure is dry.

Allow the compost to process for three to four weeks. At that time, use a pitchfork to turn the pile so the outside of the pile becomes the center.

Turn the pile every week to 10 days for three or four months, or until the compost is ready for use.

Use the compost for mulch when the pile has a rich, earthy smell and has a crumbly texture.
