The Biodynamic mark means that farms meet the organic standard including the prohibition of synthetic chemical fertilisers, pesticides, herbicides and fungicides, but then it goes much further. Emphasis is on the generation of farm inputs out of the living dynamics of the farm itself, rather than being imported from the outside. Dependence on imported materials for fertility and pest control is reduced. Water conservation is considered. Farms are required to maintain at least 10% of total acreage as a biodiversity set-aside.
This mark is audited annually.
