Jack Chambers co-founded the Sonoma Valley Worm Farm a quarter of a century ago after a surprising discovery in his home garden's compost bin. The composting worms he had bought from a local bait worm farm had processed his compost pile into a refined and nutrient-dense soil––vermicompost. Ever since then, Chambers was hooked. Now known as Terra Vesco, the worm farm is home to over 40 million composting worms called Eisenia fetida which thrive in and feast upon manure-based compost. These worms create microbially-active and fertile soils that Terra Vesco provides and sells to the local agricultural industry as well as across the country.
