“…In addition to extension and regulatory agents who help to interpret and implement these policies, advisors (e.g., nutrient consultants), NGOs, and local extension agents may serve as important actors. Further, manure may be processed (e.g., solid separation, de‐caking, composting), including as recycled bedding in the dairy and poultry industries (Bryant et al., 2021; Church et al., 2020), affecting its availability and characteristics related to off‐site transport (e.g., water content, pathogen content, odor). Contractors (e.g., manure application), custom haulers, regulatory/action agencies, retailers, and even specialized consultants (e.g., certified crop advisors) all contribute to manure processing.…”

Manureshed management—the strategic use of manure nutrients that prioritizes recycling between livestock systems and cropping systems—provides a comprehensive framework for sustainable nutrient management that necessitates the collaboration of many actors. Understanding the social dimensions of collaboration is critical to implement the strategic and technological requirements of functional manuresheds. To improve this understanding, we identified aspirational networks of actors involved in manureshed management across local, regional, and national scales, principally in the United States, elucidating key relationships and highlighting the breadth of interactions essential to successful manureshed management. We concluded that, although the social networks vary with scale, the involvement of a common core set of actors and relationships appears to be universal to the successful integration of modern livestock and crop production systems necessary for functional manuresheds. Our analysis also reveals that, in addition to agricultural producers, local actors in extension and advisory services and private and public sectors ensure optimal outcomes at all scales. For manureshed management to successfully integrate crop and livestock production and sustainably manage manure nutrient resources at each scale, the full complement of actors identified in these social networks is critical to generate innovation and ensure collaboration continuity.

“…In addition, the physiology of animals (monogastric, ruminant), their diets (protein content, phytase supplementation), and chemical manure manipulation (alum, gypsum, sodium bisulfate) all affect the fertilizer value of manure and its transport potential (Kleinman et al., 2019b). Despite this variation, dry manure is often exported from poultry, dairy, and beef production systems for use elsewhere (Bryant et al., 2022; Dell et al., 2022; Spiegal et al., 2020b).…”

“…As a strategic tool for reintegrating animal and production across scales, early visions of manureshed management focused on confined animal production systems where specialized technologies, practices, and strategies are already commonplace and are more readily envisioned (Saha et al, 2018;Spiegal et al, 2020b). Surveying manureshed management in vertically integrated U.S. poultry and hog industries, respectively, Bryant et al (2022) and Meinen et al (2022) document opportunities for implementing manuresheds in systems where grazing is absent. Through standardization, coordination, and contracts, poultry and hog industries offer predictability and scalability that has great potential for deliberate, strategic management needed to maintain manuresheds.…”

The specialization and intensification of agriculture have produced incredible gains in productivity, quality, and availability of agricultural commodities but have resulted in the separation of crop and animal production. A by‐product of this separation has been the accumulation of manure regions where animal production is concentrated. Enter the “manureshed,” an organizing framework for integrating animal and crop production where budgeting of manure nutrients is used to strategically guide their recycling and reuse in agricultural production systems where manure resources are of highest value. To move beyond regional nutrient balance analyses into the transformational realm required to mitigate “wicked” manure problems, manureshed management requires recognition of the challenges to systematically reorganizing resource flows. In better integrating crop and livestock systems, manureshed management must account for the unique nature of managing manure nutrients within individual livestock industries, anticipate trade‐offs in substituting manure for commercial fertilizer, promote technologies to refine manure, and engage extensive social networks across scales that range from the farmgate to nation and beyond.

“…The conceptual framework of the “manureshed” (i.e., the lands where surplus manure nutrients from concentrated animal feeding sites can be recycled to meet production, environmental, and socioeconomic goals) provides spatially explicit information and knowledge about where and how nutrient circularity via manure redistribution would actually work (Saha et al., 2018; Spiegal, Kleinman et al., 2020). To date, manuresheds have been designed as spatially contiguous land units: a manure hotspot is identified, and the adjacent productive agricultural lands needed to assimilate the hotspot's surplus nutrients are delineated (Figure 1a) (e.g., Bryant et al., 2021; Saha et al., 2018; Spiegal, Kleinman, et al., 2020). Here we modify the approach by defining a “circular manureshed” as the feed‐producing lands where surplus manure nutrients from animals ingesting feed from those lands can be recycled to meet production, environmental, and socioeconomic goals, where feed‐producing lands are not necessarily contiguous with the manure source (Figure 1b).…”

Recycling nutrients in the beef supply chain through circular manuresheds: Data to assess tradeoffs

Nutrient circularity can help supply chain participants meet sustainability targets. Across the segmented beef supply chain, opportunity exists to reinforce and introduce nutrient circularity by recycling surplus manure nutrients from cattle feedlots to lands where cattle feed is produced. We describe four datasets developed to evaluate options in U.S. and Canadian beef systems. The datasets delineate three “circular manuresheds,” each encompassing a hay‐grazing landscape where beef cattle are raised on grazingland and supplemented with hay grown nearby, and the distant feedlots where those cattle produce manure nutrients for potential import back to the hayfields. We selected the hay‐grazing landscapes of New Mexico, USA; Florida, USA; and western Canada (Manitoba, Saskatchewan, Alberta, British Columbia) because of their significant grazingland production and potential to substitute feedlot manure for commercial fertilizer on hayfields. In each circular manureshed, the manure nutrients from major feedlot destinations could supply a considerable proportion of the P used by hay for grazing cattle: 34% of the P requirements in New Mexico, 36% in Florida, and 6% in western Canada. The average distance to return the resource was 647 km for New Mexico, 1,884 km for Florida, and 1,587 km for western Canada. These magnitudes and distances suggest that the New Mexico circular manureshed may be the most economically viable in the current agri‐food system, but this reflects only part of a greater, multi‐factor assessment of tradeoffs. The circular manureshed concept provides a platform for simultaneous consideration of competing factors for sustainability via circularity.
