NEW! Sonoma Biochar
Sonoma Biochar is a new innovative product that improves soils in a sustainable, lasting way. While improving your soil, carbon is taken from the atmosphere, locking it into the earth for thousands of years, thereby reducing greenhouse gases. Biochar will greatly enhance the water holding capacity of your soil, conserve nutrients through its high cation exchange capacity (CEC) and help increase microbial populations and diversity.

New Program Takes Composting to the Next Level
Sonoma Compost, in collaboration with the City of Sonoma and Sonoma Garbage Collectors, launched a new program in the spring of 2011 to collect food scraps from commercial kitchens in the City. Sonoma Compost is working to establish similar programs throughout the County.
For more information on this program, please read the related article in Sonoma News.

Organic • Local • Affordable
We operate the successful Sonoma County Organic Recycling program. We produce premium quality organic compost and mulch from 100% recycled organics.
To check what materials are accepted at our site, or which ones are not, please see the Organic Recycling Guide.
Our soil products are used by Sonoma County’s most prestigious grape growers, organic farmers, backyard gardeners and professional landscapers. We also sell good quality recycled lumber and firewood at very affordable prices.
We have one of northern California’s largest selection of organic compost and mulches. Our Sonoma Compost, Organic Hi-Test Compost, Mallard Plus, Feather-Lite Amended Soil and Vineyard Mulch are all listed as “Allowed” materials with the Organic Materials Review Institute (OMRI) for use in the production of organic food and fiber. Because of our listing, you’ll find our compost used on a number of California Certified Organic Farms (CCOF).
Sonoma Compost promotes organic and sustainable management practices that minimize chemical use and emphasize preserving and rebuilding our valuable topsoil resource.
NEW! Sonoma Compost Now Produces Biodynamic Compost
Biodynamic agriculture was developed to address depletion of soils following the introduction of chemical fertilizers at the turn of the century. Biodynamic principles conceive of the farm as a self-contained organism with an integrated system of crops and livestock emphasizing food quality and soil health.
Sonoma Compost produces two Biodynamic Composts: Sonoma Biodynamic Compost (for vines, trees and native plants) and Biodynamic Hi-Test Compost (for hi-nitrogen loving crops such as vegetables).
Sonoma Compost Biodynamic Composts were developed with the assistance of experts from the Josephine Porter Institute of Applied Biodynamics and the Biodynamic Association of Northern California using the Demeter® Association’s Commercial Composting Standard as a guideline. The Demeter certification program was the first ecological label for organically produced foods.
Sonoma Compost Biodynamic Composts are created using the same process used to produce our other trusted composts. These specialty products are lab tested and listed by the Organic Materials Review Institute (OMRI) for use in organic production and are Demeter Certified for use in Biodynamic vineyards, farms, market, and home gardens. For more detailed information see our Biodynamic Compost Information.
