What is the Compost Outreach Project?

The Compost Outreach Project provides Snohomish and King County farmers with an opportunity to see first-hand the benefits of incorporating compost into their cropping systems. Our on-farm research is helping document the value of using compost in local cropping systems, and create a sustainable system for returning urban landscape and food waste energy to local farms.

Local farmers are using compost made from food scraps and yard waste!

Do you participate in food and yard waste collection? If so, you're helping to create a natural soil amendment! Food scraps then put in the food and yard waste collection become compost.
