Sonoma Compost Is Reinventing
WE ARE BACK with some products. We have been looking to serve you in any way at all. We now have a limited source of organics available. While we are finetuning the products, we are very pleased that we now have limited supplies of Vineyard Mulch, an equivalent of Sonoma Compost, Amended Soil and some firewood available. Give us a call for delivery.

Stay Connected to Bring Compost Back to Sonoma County
Many of our residents believe that a solution for our organics recycling program has been found and that a new facility will open soon. At this point it looks like a new facility is at least 5 years away. The cost to the ratepayer is about $2,000,000 per year. Meanwhile, all organics are shipped out of County. Join the Compost Coalition to stay connected (click image below).

Save Compost

Keep this topic alive. While a small group of Sonoma Compost Co's neighbors have been successful in their lawsuit to shut down local composting in Sonoma County, we can't afford to sit back. Please, click the image above to sign on and voice your support for this program.

Presentations
Sonoma Compost does presentations about on-site composting, the benefits of compost to soils, the role of compost in IPM, etc. For those who attend the presentations I leave a copy of the most recent presentation here. If you have not had a chance to attend one of the talks, it will give you a sense of what will be discussed.

Lawn Conversion: A Tool To Live With Drought
Lawn Conversion We are facing a serious drought. Everyone has to chip in to cope with the drought. If you have a lawn, lawn conversion is a green way to conserve water, soil and labor. When you remove your lawn you also remove approximately 500 years of fertile soil. The lawn that is pulled out cannot be composted, since it has too much soil in it. In the landfill it contributes to greenhouse gases. So, why not just leave it in and turn it into the foundation for a drought tolerant native landscape or vegetable garden. Simply cover the lawn with compost, cardboard or newspaper and mulch, keep moist, and nature will do the rest for you. For more information on how to do this take a look at our Lawn Conversion document.

Organic • Local • Affordable
We operate the successful Sonoma County Organic Recycling Program. We Keep It Cleanproduce premium quality organic compost and mulch from 100% recycled organics. To date over 1,800,000 tons of organics have been diverted from the landfill and turned into valuable compost and mulch.

To check what materials are accepted at our site, or which ones are not, please see the Organic Recycling Guide. Sonoma Compost does not accept compostable plastic products. Read our Pitfalls to Compostable Plastics document.

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.

OMRI LogoWe 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) and registered with the California Depertment of Food and Agriculture (CDFA) for use in the production of organic food and fiber. Because of our listing, you’ll find our compost used on many of California Certified Organic Farms (CCOF). CDFA Logo

Sonoma Compost promotes organic and sustainable management  practices that minimize chemical use and emphasize preserving and rebuilding our valuable topsoil resource.

Putting It All in Perspective
Sonoma Compost has provided compost and mulch services for over 25 years. We hope you'll enjoy this video and learn more about Sonoma Compost.

Sonoma Biochar
NOTE: TEMPORARILY OUT OF STOCK. 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.

Food Scrap 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.

Sonoma Compost Supports School Gardens
We work closely with local schools to promote organic recycling and educate school children about the importance of nature’s decomposition process. We are proud to donate compost to school garden programs and provide interesting field trips to our organic recycling facility.

Sonoma Compost Produces Biodynamic Composts
Demeter Logo 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. Next batch will be available in July). 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.
