What is it that it is forbidden to directly return livestock manure to the field?

On June 4, 22, the General Office of the Ministry of Agriculture and Rural Affairs and the General Office of the Ministry of Ecology and Environment jointly issued the Notice on Further Clarifying the Requirements for Returning Livestock and Poultry Manure to Fields and Strengthening the Supervision of Farming Pollution, which requires that the supporting facilities for preventing and controlling livestock and poultry scale farming pollution are not in place, and the manure is directly returned to the fields or discharged into the environment without harmless treatment, which does not meet the national and local discharge standards. The agricultural and rural departments should strengthen technical guidance and services, and the ecological and environmental departments should investigate and deal with it according to law.

farmers should earnestly fulfill the main responsibility of manure utilization and pollution prevention, and take measures to scientifically treat and recycle livestock manure to prevent environmental pollution. Engaged in large-scale livestock and poultry breeding should strictly implement the requirements of the Law of the People's Republic of China on the Prevention and Control of Environmental Pollution by Solid Waste, the Law of the People's Republic of China on the Prevention and Control of Water Pollution and the Regulations on the Prevention and Control of Pollution in Large-scale Livestock and Poultry Breeding, build facilities for the harmless treatment and resource utilization of manure and ensure its normal operation, or entrust a third party to realize the harmless treatment and resource utilization of manure.

Harm of returning livestock manure directly to the field

Unlike the ecological farming in the past, various drugs and feed additives are widely used in large-scale farming. With the discharge of livestock manure, returning livestock manure directly to the field without treatment is not only harmful to the soil environment, but also may threaten food safety and thus human health.

At the same time, it is also a great harm that the heavy metals in livestock manure exceed the standard. When livestock manure containing a lot of heavy metals is applied to farmland for a long time, it can cause heavy metal pollution in the soil and eventually pose a threat to human health through the food chain. Secondly, raw livestock manure contains eggs, especially chicken manure, which is the easiest to breed root-knot nematodes. Finally, the direct return of raw livestock manure to the field can easily lead to burning seedlings and roots.
