About this directory. Entries come from public government records: the USDA AMS Organic INTEGRITY Database (certified organic operations, snapshot of Oct 1, 2026) and the California Department of Food and Agriculture list of Certified Producer Certificates (as of Oct 1, 2026). County statistics are from the USDA NASS 2022 Census of Agriculture. A listing here does not mean the farm has joined CropListing or endorses it; farms marked Claimed have verified their profile. Crops are matched from the products named in each public record and may be incomplete. Farm owners can claim, correct or remove an entry from its profile page.
