摘      要：As the demand for livestock products continues to increase in China,so too does the challenge of managing increasing quantities of *** action is needed to control point source(housing,storage and processing)and diffuse(field application)pollution and improve the utilization of manure nutrients and organic ***,we review strategies to improve management at each stage of the manure management chain and at different *** strategies require infrastructure investment,e.g.,for containment of all manure *** solutions are needed to develop advanced composting systems with lower environmental footprints and design more efficient nutrient stripping *** the field-scale,there is an urgent need to develop a manure nutrient recommendation system that accounts for the range of manure types,cropping systems,soils and climates throughout *** the regional scale,coordinated planning is necessary to promote recoupling of livestock and cropping systems,and reduce nutrient accumulation in regions with little available landbank,while minimizing the risk of pollution swapping from one region to another.A range of stakeholders are needed to support the step change and innovation required to improve manure management,reduce reliance on inorganic fertilizers,and generate new business opportunities.
