“…The concept of manuresheds has recently been introduced, built on a model similar to watersheds, as a tool to better understand and troubleshoot issues surrounding the recycling of manure nutrients (Kleinman et al., 2022; Spiegal et al., 2020). A manureshed framework is also useful for examining AR, a critical concern with land application of fecal wastes (Durso & Cook, 2014).…”

Field application of beef cattle feedlot runoff may transport manure‐borne microbes and antibiotic resistant bacteria to agricultural soils eventually impacting deeper soils and groundwater. To evaluate this potential, total soil, antibiotic resistance (AR), and fecal indicator bacteria (Escherichia coli and Enterococcus) and the presence/abundance of AR genes were examined to a depth of 1.8 m in an agricultural field receiving long‐term application of feedlot runoff and compared to a nearby pasture receiving no runoff. While plate counts of total soil bacteria and cefotaxime‐resistant, erythromycin‐resistant, and tetracycline‐resistant bacteria decreased with depth on both fields (p < 0.001) by an average 2‐log10 colony forming unit g−1 to 1.8‐m depth, field differences were only observed with greater abundances of total soil and erythromycin‐resistant bacteria (p ≤ 0.026) in the runoff‐amended versus control field soils. Soil bacterial and fecal indicator bacterial isolates evaluated phenotypically for resistance to 12 antibiotics varied in range and sensitivity. Using a culture‐independent approach, erm(C) and tet(Q) were detected using polymerase chain reaction in 31% and 58% of runoff‐field samples throughout the soil profile. Detection of erm(C) and tet(Q) in the control field soil profile was less frequent (0% and 11%, respectively). Two other genes, erm(A) and tet(X) were not detected in any soil samples. Based upon these results, long‐term applications of beef cattle feedlot runoff may increase the total abundance of microorganisms in the surface and shallow soil, but the relative enrichment of AR was dependent upon the type of resistance evaluated and, more specifically, the genes targeted for analysis.

“…Although manureshed‐based nutrient management strategies are proposed to improve manure nutrient use efficiency and benefit environmental quality and economic returns (Kleinman et al., 2022), quantitative evaluations of water quality benefits are lacking. Evidence of the benefits (and potential inadvertent drawbacks) of manureshed management is needed to support investment in implementation of the strategy and promote its adoption.…”

Manureshed management guides the sustainable use of manure resources by matching areas of crop demand (nutrient sinks) with areas generating livestock manure (nutrient sources). A better understanding of the impacts of manureshed management on water quality within sensitive watersheds is needed. We quantified the potential water quality benefits of manureshed-oriented management through scenario-based analyses in the Susquehanna River Basin (SRB) using the Soil and Water Assessment Tool. Five manureshed management scenarios were developed and compared with a baseline "business-as-usual" scenario. The baseline assumes manure is less transportable, which means some locations have manure application in excess of crop demand. The "watershed nutrient balance" scenarios assume excess manure from surplus locations is transportable and that manure is applied around the SRB based on crop nutrient demand. The "watershed nutrient balance avoiding runoff prone areas" scenarios assume manure is transportable but not applied in vulnerable landscapes of the SRB. Each scenario was evaluated under two application rates considering crop nitrogen demand (N-based) and phosphorus demand (P-based). Phosphorus-based manureshed management was more effective in water quality improvements than N-based management. Phosphorus-based nutrient balance scenarios simulated 3 and 25% reduction in total N (TN) and total P (TP), respectively, from the baseline scenario at the watershed outlet. The N-and P-based

“…However, in livestock-intensive regions the production has raised environmental concerns, among which undesirable nutrient losses from livestock farms and their subsequent consequences on eutrophication in downstream water bodies have gained worldwide attention (Li et al, 2015;Sharpley et al, 2015;Kleinman et al, 2020). In livestock-intensive regions, particularly, manure is often an important (if not predominant) source of nutrients applied to the agricultural land and also a key contributor of nutrient loads in the stream (Johnes et al, 2022;Kleinman et al, 2022). In Norway, it has been estimated that livestock manure accounts for roughly 50 % of the total phosphorus (P) and 25 % of the total nitrogen (N) supplies to agricultural lands (Kolle and Oguz-Alper, 2020).…”
