  Proud to be Organic and Sustainable
Sonoma Compost is a leader in the movement toward more sustainable growing systems, whether in the backyard, commercial landscape or on large agricultural parcels.

We verify that Sonoma Compost, Organic HI-TEST Compost, Mallard Plus, Vineyard Mulch, and Sonoma Feather-Lite Amended Soil are all currently listed as "Allowed" materials for use in organic production by the Organic Materials Review Institute (OMRI). Organizations such as California Certified Organic Farmers (CCOF) rely on OMRI to provide guidance on whether particular products are allowed inputs for certified organic farms.
