• The 2017 S1032 Annual Meeting was held in 219 LW Chase Hall, University of Nebraska’s East Campus, Nebraska, May 22-24, 2017. The meeting was hosted by Richard Koelsch. The meeting consisted of a tour of University of Nebraska research beef feedlot on Monday (May 22). A total of 22 people attended the meeting on Tuesday (May 23). Tuesday’s program include three presentations: (Positioning the USMARC as a Model System for Antibiotic Resistance Transfer Research - Tommy Wheeler; Pasture Systems and Watershed Management Research Unit: Approach to System Modeling of Nutrient Flow Through Agricultural Systems - Alan Rotz; Assessing the long-term consequences of nitrogen and phosphorus losses from a grow-finish swine facility - Brooke Latack); group discussions for reviewing the current project objectives and status; and breaking out groups to brainstorm assigned questions to show how we can link our individual research in animal protein production via the CLD. A total of 17 people attended the business meeting on Wednesday (May 24). Luis F. Rodriguez provided INFEWS-ER updates and discussion on how to participate. As part of the business meeting, the new project writing team was identified. Members agreed to continue monthly webinars starting from September 2017, and to have the 2018 meeting in Washington DC.   
• Brent Auvermann and Rick Koelsch initiated weekly proposal-development web-conferences for the S1032 group in fall of 2016. AFRI priorities and proposal ideas were discussed. Weather variability and a changing climate creates critical vulnerabilities for animal feeding operations was identified as one topic. Examples of those vulnerabilities include: animal feed supply disruptions, increasing animal stress due to increasing temperatures and wet periods, greater risks to storage of manure, increasing disease/health risks for animals and human, extreme events disrupting and displacing AFOs and their managers, inability to recycle nutrients through land application systems.
• On behalf of S1032, Deanne Meyer from UC Davis worked with Carol Barford from the University of Wisconsin on a dairy data dictionary to move the group toward data harmonization. One webinar was devoted to an update of data harmonization progress and had participation from National Ag Library staff and U. Wisconsin on a monthly webinar. Deanne Meyer also participated in the NSF INFEWS PI meeting.
• Steven Safferman from Michigan State University is preparing a comprehensive literature review on winter manure application and soil health in conjunction with the North Central Water Network and Soil Health Institute. As part of the effort, an annotated bibliography of all related articles will be prepared and housed on the new Soil Health Institute Landscape Tool. Last literature review was published over 10 years ago.
• Teng Lim from University of Missouri is conducting a small project that assembles and analyzes soil health variable and land application of manure data, and compare the findings with a set of field plot data that are more controlled and replicated over the years. Key variables indicating soil health include water-stable aggregates, bulk density, and organic/active carbon.
• Erin Cortus engaged in a grant proposal that leveraged S1032 goals and collaborations, as well as connections with the INFEWS-ER Project (PI Rodriguez). This grant proposal engaged investigators outside of S1032 in the disciplines of natural resource management, agricultural economics and agricultural education. The proposal was titled “Curriculum Development for Wicked Problem Solving”, led by Dr. Benjamin Turner (Texas A&M University Kingsville). The proposal status is Under Review.
• Jacek Koziel made major progress to solve the livestock odor problem. A bio-based, soybean-derived, mitigates ammonia emissions up to 68%, major odorous volatiles up to 90%, without significant increase in nitrous oxide emissions. (2) “INFEWS/T4: The INFEWS-ER: a Virtual Resource Center Enabling Graduate Innovations at the Nexus of Food, Energy, and Water Systems” (Jan 2017 – Dec 2020) project was initiated (Koziel, co-PI). (3) Novel ‘aerobic-digestion & trench burial’ hybrid system was developed for biosecure and rapid disposal of infectious animal carcasses.  Lab-scale research warrants field-scale studies. 
• Shafiqur Rahman, North Dakota State University is working with nanoparticles in mitigating hydrogen sulfide and greenhouse gas emissions. In this study, Alginate-nZnO beads or bare nZnO proved to be an effective NP in reducing H₂S (up to 99%), CH₄ (49-72%); and CO₂ (46-62%) from manure stored under anaerobic conditions and these reductions are likely due to the microbial inhibitory effect from nZnO, as well as chemical conversion. Both SEM-EDS and XPS analysis confirmed the presence of zinc sulfide (ZnS) in the beads, which is likely formed by reacting nZnO with H₂
• Luis Rodriguez, Illinois, is the PI of the NSF INFEWS project entitled, “INFEWS/T4: The INFEWS-ER: a Virtual Resource Center Enabling Graduate Innovations at the Nexus of Food, Energy, and Water Systems”. The project has hosted a kick off meeting in April 2017. The members of S-1032 represent most INFEWS-ER steering committee membership. The project management team is in the process of recruiting participanting Faculy Fellows and Graduate Students to develop and enjoy learning modules. The INFEWS-ER is developing a website for hosting of learning modules targeting the development of graduate training in transdisciplinary food, energy, and water research. The inaugural symposia is tentatively schedules to occur in February of 2018.

Objective 2. Facilitate organization, synthesis, and integration of component-based research findings and supporting data.

The underlying premise of this objective is that project participants collaborate or work together in teams to build a component(s) of the relational aspects of animal protein production presented in the CLD. Participants will make/share data available to support the CLD work via a publicly accessible database.    Planned activities to meet this objective include: (1) identifying the types of data participants have or being generated in their current work and (2) designing and hosting a publicly accessible database for sharing project data by participants to facilitate development/integration of system components outlined in the CLD (figure 1). The accomplishments towards achieving this objective include:

• Project participants continue to identify and update the nodes relevant to their work and also indicated sets of data they have available to share, as listed in table 1.
• Some examples of specific data available and/or current research activities by project participants to generate data for potential use in completing the CLD are listed below.
  • Arkansas: Jun Zhu’s group continued their research on anaerobic digestion of poultry litter to produce renewable energy with focus on developing kinetic models to describe the digestion process. The Gompertz model was used and modified based on the experimental data and a new kinetic model was developed. The group still are working on the cleanup methods/technology in water recycling because this is still the major bottleneck for treating poultry litter using anaerobic digestion. Avoiding adding a large amount of water to litter to make it a liquid for the process has not made much progress. New methods such as non-thermal plasma technology, may need to be looked at to reduce the contaminants in the effluent water from the digester so that it can be recycled back to the digester. Other water cleaning technologies will also be investigated as well.
  • California: Deanne Meyer and Carol Barford are currently interacting with French scientists who developed Animal Trait Ontology for Livestock. https://bioportal.bioontology.org/ontologies/ATOL. A separate dictionary is used by pork ISIC (http://unstats.un.org/unsd/cr/registry/regcst.asp?Cl=27).
  • Iowa: Researchers led by Koziel continued to improve four mitigation technologies for odor and gaseous emissions from swine and poultry operations. Development and testing follows gated approach from lab- to pilot-, and finally to farm-scales.  (1) Soybean-based treatment in a form of pit manure additive was tested on farm-scale. Non-sulfur VOC emissions were reduced by 36%. Ammonia emissions were reduced by 22%. Hydrogen sulfide emissions were reduced by 80%. No significant change to greenhouse gases emissions were observed. Estimated material cost of treatment is $1.45 per pig, equivalent of ∼8% of the pig market price.  (2) Biochar was tested on a pilot-scale as a pit manure additive.  Significant reductions in emissions were observed for ammonia (12.7–22.6%). Concomitantly, significant increases in methane emissions (22.1–24.5%) were measured. (3) Black light was tested on both laboratory and pilot-scale at a swine operation.  Treatment reduced p-cresol emissions by 22%. Treatment reduced odor emissions by 16%. Treatment reduced nitrous oxide (a greenhouse gas) emissions by 9%. (4) Microbial-mineral treatment for surficial application to poultry manure was tested.  Reduction levels of odorous volatile organic compounds was between 9% and 96% for microbial-mineral additive, depending on the analyzed compound.
  • Idaho: Lide Chen’s team focused on mitigating gas emissions from manure application lands by using filtration/low sprinkler head irrigation and manure nutrient recycle by solid separation. They also conducted nutrient uptake research for which duckweed strains were cultivated on anaerobically digested dairy manure. Both lab and on-farm tests have been carried out. Preliminary data analysis has been conducted.
  • Kansas: Zifei Liu’s group conducted a comprehensive review of life cycle assessment on carbon footprint of beef production in the US. The study will offer (1) an initial critical review on types of LCA methodology and allocation method used, the scope, scale and system boundary defined in the LCA applications in beef production; (2) an LCA comparison of different beef systems; (3) a ranging of results on carbon footprint of beef production based on conditions of the US beef production, trends in various indicators and the current data gap. Results of the LCA will be expressed in the unit of carbon footprint per kg product, and the main sources of uncertainty in the results will be identified. The results will provide a better understanding of the whole-farm greenhouse gas (GHG) emissions from beef production, including emissions from feed production, from the enteric fermentation of the cattle, from the cattle's waste, and from processing and transportation, and the relative contributions of different system components.
  • Michigan: Steven Safferman is maintaining online, publically available decision support tools to convert animal waste into a resource. Specifically, the Michigan Waste Biomass Inventory to Support Renewable Energy (Inventory) maps organic wastes in Michigan and conducts preliminary energy modeling. Included in the Inventory is manure from animal agriculture facilities. The Anaerobic Digestion Development Iterative Tool and the Combustion Renewable Energy Development Iterative Tool are companion tools to model the economic, renewable energy production, and greenhouse gas emissions reduction from blended feedstocks. Research is conducted on the development of a holistic phosphorus fate and transport index that includes consideration of manure application during different seasons. A major goal is to identify site-specific best management practices that maximize beneficial nutrient utilization while minimizing runoff.  The research entails modeling the complex system using Hydrus and running various scenarios, typical of the Great Lakes states, to establish the index.
  • Minnesota: A multidisciplinary team is conducting several research and demonstration projects with the overall goal to identify major energy uses for swine and dairy production and identify renewable energy options to replace fossil fuels (B19). The team measured energy use on two dairy and swine farms. They installed photovoltaic solar systems and monitored their energy production. Data collection and analysis is ongoing. New projects to install another photovoltaic system and provide sow cooling and piglet heating were funded.
  • South Dakota: South Dakota has been working with colleagues at North Dakota State University and several centers of the USDA-ARS to collect and aggregate environmental and production data for confinement cattle operations in the Northern Great Plains. The data are being integrated into (through validation of or alterations to) the Integrated Farm System Model (v4, Rotz et al, 2016). This model incorporates multiple loops and nodes indicated in Figure 1 including, but not limited to B4, B5, B11 and R10. Initial simulations of cattle feeding systems (open lot, bedded pack) of varying capacities (750, 1500, 5000) in multiple locations in ND, SD and NE have been simulated for both current and projected climate conditions. The initial simulations provide a baseline for both system understanding and model evaluation.
  • Virginia Tech worked on developing a compartmental based processed based model to improve the accuracy of estimating aerial emissions from stored dairy manure. The model estimates (i) spatial variation of temperature and substrate concentration (ii) spatial variations and rates of biogeochemical processes, and (iii) production and emission of ammonia from a liquid manure storage tank. Model performance was evaluated using experimental data obtained from National Air Emissions Monitoring Study. A sensitivity analysis was performed and air temperature, manure pH, wind speed, and manure total ammoniacal nitrogen concentration were identified as the most sensitive model inputs. Model simulations were run to estimate ammonia emission under different management and weather scenarios: two different manure storage periods in cold season from November to April and in warm season from May to October using historical weather data of the Rockingham County.

Objective 3. Discover (reveal), substantiate, and interpret the broader impacts of component-level modifications to animal production systems.

In Arkansas, the results from research provide new knowledge and useful information based on which further investigation of using liquid anaerobic digestion technology to treat a solid waste substrate such as poultry litter can be planned. The kinetic models developed can be applied to simulate the digestion process without having to conduct actual experiments, thus saving research costs while still obtaining important information on the performance of the digestion process so that better operating strategies can be explored and experimented. The ultimate product will be a better digestion technology that can be implemented at farm level for poultry producers to handle/abate the nutrients in poultry litter to reduce the environmental liability of their productions.

In California, annual report data quality submitted by dairy farmers was evaluated by determining if reported values were consistent with mass balance analyses of 1) excreted nutrients and, 2) land-applied N. This study compared the sum of excreted nutrients to that of applied and exported nutrients submitted in annual reports and used simulations to determine if reported N-application rates were reflective of existing agronomic limitations.  Findings indicate opportunities for improvement likely exist in quantification of solid or liquid manure applied to land or plant material harvested from land. Additionally, opportunities for improvement in obtaining a representative sample likely exist. Progress is being made to define uncertainty introduced at farm level to determine amount of N, P, and K, removed from (as crops) fields where manure was applied.  Each load of chopped forage from nine fields (3 each planted in corn, sorghum and cereal forages) was weighed and sampled for moisture and nutrient composition.  This detailed dataset is useful to identify how different sampling protocols impact uncertainty of the answer. Work has begun to measure total and volatile solids as well as nutrient flows through commercial dairy operations (n=4 or 5).  This is a one year field project. It will provide data to evaluate.  Modification of previously developed eLearning decision support system occurred to aid dairy operators and consultants understand importance of collecting representative samples and quantification of material applied to land and removed as crops.

In Minnesota, a multidisciplinary team has developed educational materials and tools to convey critical concepts to enhance biosecurity for poultry and swine production facilities. A Biosecure Entry Education Trailer (BEET) was developed and videos produced to demonstrate key principles of Danish Entries. The BEET has been used with veterinary students, FFA members, company employees and producers. Presentations were made to producers groups in Minnesota and Missouri. In Minnesota, many sow barns use filter all air coming through inlets to reduce the airborne spread of porcine reproductive and respiratory syndrome virus (PRRSV). Recent research reported leakage rates for sow barns. A model was developed to estimate indoor virus concentrations in a leaky sow barn with filtered inlets and a negative-pressure ventilation system.

In Iowa, Soybean-based treatment in a form of pit manure additive for mitigation of odor and gaseous emissions was developed and tested on a farm-scale. Significant reduction of main odorants was observed with no significant change to greenhouse gases emissions. Estimated material cost of treatment is $1.45 per pig, equivalent of ∼0.8% of the pig market price. Major advances were made to move black light treatment of odor and gaseous emissions from lab- to pilot-scale.  Emissions of odor and one key greenhouse gas were reduced.
