To produce the annual Mercaris Organic and Non-GMO Acreage Report, Mercaris utilizes state-level, crop-specific organic operation data collected from the OID to estimate the annual number of certified organic operations per state and by crop. Mercaris also analyzes ERS and NASS national and state-level organic operation size data beginning in the year 2000 to estimate average size and crop rotation practices for organic operations at the state level, and on a per-crop basis. Employing this methodology, Mercaris is able to more accurately capture the full size of the organic agriculture industry in the U.S. as well as provide acreage estimates for the current year.
