Manure Share Program

The OCWC Manure Share is a free manure exchange program for ARIZONA Residents and Business Owners that brings gardeners and landscapers searching for organic materials for use in composting or field applications in contact with farmers and livestock owners who have excess manure.

This benefits the water quality of the Oak Creek Watershed by removing excess nutrients from farms and ranches and by lowering the amount of commercial fertilizer used by gardeners and landscapers.

    Composting Glossary

    Helpful terms for completing our Manure Share signup:

    BEDDING: Dry absorbent materials used to provide a dry lying surface for livestock. Bedding materials such as paper, saw dust, wood pellets, and wood shavings absorb moisture from livestock wastes, the soil, and the environment.

    COMPOST: Completely decayed organic matter. It is dark, odorless, and rich in soil benefits, making it easier for plants and other organisms to absorb.

    COMPOSTING: The process by which gardeners convert organic matter into compost. The aerobic or anaerobic decomposition of organic and biodegradable material results in a nutrient-rich growing medium and soil amendment.

    MANURE: The fecal and urinary excretion of livestock and poultry. Sometimes referred to as livestock waste. This material may also contain bedding (see above), spilled feed, water, or soil. It may also include wastes not associated with livestock excreta, such as milking center wastewater, contaminated milk, hair, feathers, or other debris.

    MULCH: A material spread over the soil surface to conserve moisture and porosity in the soil underneath and to suppress weed growth. Mulch should not generally be mixed into the soil; it is not a fertilizer or soil amendment. There are many types of mulch, including partially decomposed compost, bark, wood chips, hay, nut shells, grass clippings, pine needles, straw, and others. The point is to cover bare ground so that top soil is not washed away, soil temperature is buffered, and weeds are reduced from lack of light. A good organic mulch will also supply nutrients to the earth as it decomposes. Often used for landscaping and erosion control, but does not have the soil and plant nutriment value and composition of rich, clean, compost.

    ORGANIC system: Any material in the soil that was originally produced by living organisms, plant or animal.

    YARD WASTE: grass clippings, leaves, and weeds and shrub and tree prunings six inches or less in diameter from a residence or business.

    YARD - aka CUBIC YARD: A unit of measure equivalent to 27 cubic feet or 22 bushels. A cubic yard of compost-manure weighs approximately 900 lbs = about 0.45 tons. A box that is I yard wide, I yard long, and I yard high has a volume of I cubic yard. A cubic yard is often loosely referred to as a "yard" (for example, a one-yard bucket).

How the Program Works - Sign-Up

For ARIZONA Residents and Business Owners who want Manure

especially for gardeners or landscapers

1. Sign up for our Manure Share List below. We require this for the security of the personal information we are providing. Decide how you can haul it safely. Make arrangements to have a pick-up or other vehicle available, if necessary.

2. Use our Manure Share List Search to lookup list members who have manure. Note: You will not be able to log into your account until your email address is verified.

3. Arranging A Pick-Up Time: Contact the member to obtain information on where and when the manure or compost can be picked up.

4. Composting the Manure: Participating livestock owners are encouraged to fully compost their manure. However, some farms may have only fresh manure available. You are encouraged to compost the manure in your own compost pile prior to using it. There are risks to you and your garden if the manure is not composted.

Review our MANURE SHARE RESOURCES to help you understand guidelines for use of manure in home compost systems.
