US requires composting of manure unless it is applied to land used for a crop not intended for human consumption or it is applied 90/120 days prior harvest of a product for human consumption (depending on whether the edible portion has direct contact to the soil or not)


EU Regulation 2092/91 requires that the quantity of manure applied annually may not exceed 170 kg of nitrogen/year/ha; US does not. US sets restrictions on the time between application of raw manure and the harvest of crops for human consumption; this is not addressed by EU. EU requires controlled fermentation and or appropriate dilution of slurry/urine; US sets restrictions only if applied on land used for a crop intended for human consumption. EU sets specific requirements for the capacity of manure storage facilities; US does not. EU requires consideration of the source of manure allowing manure from organic production units and regulating the amount of manure from conventional sources. EU prohibits manure from "factory farms" (but still allows from "extensive husbandry" under certain conditions). US does not address manure source.


Raw manure contributes significant benefits to soil nutrient, structure, and biological activity that other soil fertility practices and materials do not provide. The responsibility to use raw manure in a manner that is protective of human health applies to all producers, whether organic or not, who apply such materials. USDA acknowledged the commenters who noted that the OFPA cites food safety concerns relative to manure use and, therefore, that food safety considerations should be reflected in the practice standard for applying raw manure in the final rule.
