CNG farmers don’t use any synthetic herbicides, pesticides, fertilizers, or genetically modified organisms. CNG livestock are raised mostly on pasture and with space for freedom of movement. Feed must be grown without synthetic inputs or genetically modified seeds.
So how is CNG different than Certified Organic?
CNG is a private non-profit organization that's not affiliated with the USDA's National Organic Program. CNG's certification approach is based on the participatory guarantee system (PGS) model that relies on peer reviews in which inspections are typically carried out by other farmers. The PGS model promotes farmer-to-farmer knowledge sharing about best practices and fosters local networks that strengthen the farming community. This model uses an approach that minimizes paperwork and keeps certification dues affordable.
