	abstract = {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{\textquoteright}s {\textquotedblleft}mega-manureshed,{\textquotedblright} 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.},

	abstract = {US poultry production and processing industries provide close to 2 million jobs and have annual economic impact of close to $500 billion. In 2019, over 9 billion broiler chickens were produced across the US with 60\% or so concentrated in southeastern states. The production of approximately 1.2 kg of manure per broiler chicken poses daunting challenges in terms of beneficial use that is economically and environmentally acceptable. The issue is exacerbated due to production and processing being located in relatively small confined spaces. Currently, opportunities for transporting surplus manure from confined animal operations for use on nutrient-deficient crop and hay lands elsewhere are limited. A potential solution recently proposed by the USDA{\textquoteright}s LTAR Network study is the concept of {\textquotedblleft}Manureshed{\textquotedblright} {\textendash} the lands surrounding confined animal operations onto which manure nutrients can be redistributed to meet production, economic, and environmental goals. Using this concept, this presentation reviews the manure management issues within the poultry production and processing industry and seeks to explore opportunities for intra-county pathways for redistribution of poultry manure nutrients to recouple crop-livestock agricultural systems disconnected for some time due to specialized livestock production industries. Key case studies where local accumulation of poultry manure nutrients are manifest at forefront at a national scale will be examined.},
