Manureshed management seeks to address systemic imbalances in nutrient distributions at scales beyond the farmgate and potentially across county and state boundaries. The U.S. poultry industry, which includes broilers, layers, pullets, and turkeys, has many characteristics that are compatible with achieving a vision of manureshed management, including a history of engaging in local and regional programs to better distribute manure resources. Despite widespread vertical integration that supports large-scale strategic decision making and dry manures that favor off-farm transport, there are still many challenges to poultry manureshed management that require engaging stakeholders other than just the poultry industry. Analysis of county-level nutrient budgets highlights the industry's “mega-manureshed,” extending from the Mid-Atlantic, across the southeast, and into northwest Arkansas, Oklahoma, and Texas. The analysis also identifies areas with legacy nutrient build-up that are still present today. Implementing manureshed management in the U.S. poultry industry requires comprehensive consideration of manure treatment technologies, alternative uses such as bioenergy production, market development for treated manure products, transport of manure nutrients from source to sink areas, and manure brokering programs that promote manure nutrient distribution. Fortunately, past and present evolution and innovation within the industry places it as a likely leader of the manureshed vision.

家禽粪肥管理：垂直整合行业的机遇和挑战

粪肥管理旨在解决农场大门以外以及可能跨越县和州边界的养分分布的系统性失衡。美国家禽业，包括肉鸡、蛋鸡、小母鸡和火鸡，具有许多符合实现粪肥管理愿景的特征，包括参与地方和区域计划以更好地分配粪肥资源的历史。尽管广泛的垂直整合支持大规模战略决策和有利于场外运输的干粪，但家禽粪肥管理仍然存在许多挑战，需要参与家禽行业以外的利益相关者。县级营养预算分析突出了该行业的“大型肥料”，从大西洋中部延伸，穿过东南部，进入阿肯色州西北部、俄克拉荷马州和德克萨斯州。该分析还确定了今天仍然存在的遗留养分积累的区域。在美国家禽业实施粪肥管理需要全面考虑粪肥处理技术、生物能源生产等替代用途、处理过的粪肥产品的市场开发、粪肥营养从源头到汇区的运输，以及促进粪肥营养分配的粪肥代理计划。幸运的是，该行业过去和现在的演变和创新使其成为肥料愿景的可能领导者。家禽业需要全面考虑粪肥处理技术、生物能源生产等替代用途、处理过的粪肥产品的市场开发、粪肥养分从源区到汇区的运输，以及促进粪肥营养分配的粪肥经纪计划。幸运的是，该行业过去和现在的演变和创新使其成为肥料愿景的可能领导者。家禽业需要全面考虑粪肥处理技术、生物能源生产等替代用途、处理过的粪肥产品的市场开发、粪肥养分从源区到汇区的运输，以及促进粪肥营养分配的粪肥经纪计划。幸运的是，该行业过去和现在的演变和创新使其成为肥料愿景的可能领导者。
