Under the NOP there are specific requirements for the use of raw manure.
Raw animal manure must be composted unless it is:
Grazing animals are not subject to the restrictions of raw manure application. We encourage the use of animals in crop rotations; however, we do not encourage the use of grazing animals in crops that are harvested for fresh consumption.
Heat-treated manures or processed manures may be used without these restrictions as they are treated to prevent the contamination of organic crops. Remember to seek approval of new materials, including manure-based products, prior to using.
