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’s LTAR Network study is the concept of “Manureshed” – 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.
