Compost offers many benefits to the landscape and garden. For example, compost:

•   Increases the soil's ability to hold water and nutrients;
•   Supports living soil organisms;
•   Helps dissolve mineral forms of nutrients;
•   Buffers soil from chemical imbalances;
•   May provide biological control of certain soil pests; and
•   Helps return organic materials to the soil, and keeps
    them out of landfills and waterways.

Compost can be used as a mulch, a liquid "fertilizer", or incorporated into the soil or potting mixes.
