West Marin Compost is very pleased to announce that a proposal they wrote on behalf of the Lafranchi Dairy was awarded a $744,000.00 grant to convert the dairy from a wet flush manure collection system to a dry scrape system. Under the current system, water flushes manure out of the barns. The slurry enters a manure separator and the liquid runs into a manure pond. This liquid is like a manure tea, rich in nutrients and carbon. As a result, as the manure tea sits in the pond, methane is produced. The dry scrape system will eliminate the flushing. The nutrients will remain in the manure and very little manure water will enter the pond. What does enter the pond can be used to bring the compost to optimum moisture levels. The now more nutrient rich manure will enhance the compost produced. This is a win-win-win scenario for the dairy, the compost operation and the environment. http://www.marinij.com/business/20180212/west-marin-ranch-gets-grant-to-reduce-greenhouse-gas
West Marin Compost is constructing free wattles (for fire relief), which have been inoculated with mycelium to provide bioremediation for the fire affected lands in Sonoma County. The wattles, long 8″ diameter socks that are filled with straw, compost and mulch, will be placed in areas where the risk of run-off of water contaminated with oil, gas, pesticides, leaded paints, chemicals, etc. is a risk to the environment, particularly our water resources.
The Lafranchi Family have donated all of the straw bales from the Nicasio Pumpkin Patch. Gourmet Mushroom, Inc. is providing the fungi. Clean River Alliance transports the fungi substrate to our facility. Many volunteers are chipping in providing labor to put the whole package together with West Marin Compost providing compost, mulch, wattle socks, equipment, labor, coordination and transportation.
Volunteering is on hold. Stay tuned
How does it work? The wattles will provide erosion control by slowing down the water, allowing sediment to settle out and reducing the energy of the water. Compost in the wattles has the ability to immobilize heavy metals, thereby removing them from the environment. The microbes in the wattles see hydrocarbons (gas, oil, many pesticides) as a food source and will break them down. The added fungi are vey good in filtering out heavy metals, chemicals and hydrocarbons. We are building bioreactors, where nature can do its work to clean up.
Seasonal Sale! From time to time we may offer seasonal products on sale. Check here what may be available. June special: Ultra-Light Mulch Made from quick composted horse manure. Just processed long enough to neutralize odors, kill weed seeds and potential diseases, and to obtain a nice dark brown uniform color. As the name implies, this mulch is nice and light, making it easy to work with. It is screened to <1.5″.

Dairy manure separator solids are combined with approximately equal volumes of green and equestrian materials, formed into windrows on the composting pad and watered as needed. Any runoff from the compost area flows to the dairy’s liquid waste storage ponds. Windrows are managed in accordance with CAL Recycle and USDA National Organic Program (NOP) guidelines to reduce pathogens and weed viability to negligible levels. A mechanical screen is used to separate coarse from fine material at the end of the process.
Because finished compost is a dry material (typically less than 50% moisture at maturity, it is less costly to spread than wet manure (typically 75-95% water). Finished compost is odorless and the nutrients it contains are much less mobile under rainfall conditions than manure. In fact, compost is often used as an erosion control material to help prevent soil movement on disturbed sites. Properly composted material does not contain viable weed seeds, which liquid manure often does, so spreading compost does not spread thistles or other weeds.
