The meeting was held at Ramada-Mall of America, Bloomington, Minnesota from June 19 to 21, 2012. There were 32 participants. Tuesday Morning, June, 19, 2012: Sub-committee for the regional coordinated agricultural project on tall fescue held a discussion. In the afternoon, Chuck West reported to the NCCC-31 group the outcome of the discussion. NCCC31 meeting started Tuesday afternoon at 1:00 PM. Greg Cuomo was the local host, Xuejun Dong the chairperson. As Marvin Hall (this year's Secretary) was not able to attend the meeting, Steve Barnhart volunteered to take the minutes (see attached file). Administrative Advisor Dr. Jim Kells gave updates on the current status of the NCCC-31, as well as instructions for the upcoming mid-term review in early 2013. He indicated that the impact statement will need to be revised and posted on the NIMSS website based on past two years' activity impacts. Rebecca McCulley volunteered to lead this revision effort. Jim reminded to group to submit this year's annual report within 90 days of the meeting. Beth Nelson, President of both the National Alfalfa & Forage Alliance and Midwest Forage Association, gave a report on some of the coordinated lobbying efforts of the associations she represents for funding and support for forage research and activities. Xuejun Dong appointed three working committees: Locations: Jennifer MacAdam, Howard Skinner, and Matt Sanderson. Nominations: Bill Lamp, Rebecca McCulley, and Ben Tracy. Resolutions: Dave Barker, Jeff Volenec and Todd White. Howard Skinner (PA), Tom Griggs (WV), Rebecca McCulley (KY), and Kim Cassida (MI) delivered their state reports (each 20 minutes, followed by 10 minutes discussion). Wednesday, June 20, 2012 The following six researchers delivered their state reports: Craig Sheaffer (MN), Chuck West (AR), Ben Tracy (VA), Todd White (KS), Anowar Islam (WY) and Jeff Volenec (IN). The group attended a one-hour video conference with Dr. Jim Dobrowolski on Ag budget and funding with NIFA. This was followed by a field tour featuring ongoing forage studies by scientists at University of Minnesota and UDSA-ARS. Thursday, June 21, 2012: Chuck West gave a brief description of the on-line bioenergy course coordinated by the U. of Arkansas. The three committees gave their reports: The Locations Committee recommended next NCCC-31 meeting to be held in Kentucky, with dates to be determined. The Nomination Committee proposed that Tom Griggs be appointed as Secretary for 2013 with expected advancement to Chair in 2014.

Accomplishments

1. NCCC-31 scientists continued the active communication and information exchange among members, which has been a tradition for this group in past 60 years. Given the accelerated pace of scientific advancement and rapid expanding of literature in the area of eco-physiology-based forage management, the timely face-to-face communication and information exchange during the NCCC-31 annual meeting becomes of paramount importance for individual members to avoid duplicating research efforts in problems that have already been solved but not been published, and to consolidate individual research efforts to unique, most important research questions. Interaction of the NCCC-31 group with Dr. Jim Dobrowolski, National Program Leader of NIFA's Division of Environmental Systems, and Beth Nelson, National Alfalfa Improvement Association (NAIA), reinforced the group's involvement in national panels for forage funding and research planning. Interaction of the group with Fae Holin, Editor of Hay & Forage Grower magazine, provided possibility for connecting research findings of NCCC-31 scientists directly with producer groups. 2. The information exchange fostered efficient coordination and fruitful collaboration among members and led to the birth of two highly coordinated research activities involving a number of members of this group: (a) a common alfalfa-tall fescue mixture experiment across the north-central USA involving seven NCCC-31 members representing seven states; (b) a regional integrated Coordinated Agricultural Project (CAP) planning grant ($50,000) to coordinate the development of a full proposal, in which several NCCC-31 members serve as core writers with involvement of the region's leading researchers in life cycle analysis, soil science and climate change modelers. See below for impact statements. 3. During this reporting period, NCCC-31 researchers published 80 peer-reviewed journal papers, eight book chapters, one edited book, 36 extension papers, 59 conference abstracts/posters, eight reports/proceedings, and six referred popular articles.

Impacts

  1. Tall fescue is the most widely utilized forage species from the central Corn Belt to the southeastern U.S. and supports large, forage-based beef and dairy numbers. The regional integrated CAP planning project led by NCCC-31 researchers is channeling the region‘s leading scientific resource into the quest of guiding principles for optimally managing the livestock grazing systems in the humid east region to enhance soil carbon (C) sequestration, improve water and nutrient storage, mitigate the climate-forcing effect of fossil fuel combustion, and potentially provide producers with C credit income.
  2. The cost of nitrogen fertilizers and weed control constrain sustained forage production. A common alfalfa-tall fescue mixture experiment across seven states in the North-central USA has been implemented by NCCC-31 researchers and data collected are being analyzed for nitrogen replacement value and for the effect of grass-legume mixtures in deterring weed invasion. This coordinated study will also quantify the variability of production of the tall fescue-alfalfa mixtures across north-central USA, which is difficult to fathom based on meta-analysis of published individual studies.
  3. NCCC-31 researchers continued to provide scientific information useful for forage producers. Examples include (a) the finding by Virginia researchers that forage productivity in cool-season regions could be improved with minimal external inputs by adding pastures sown with moderately diverse (n=4-10 species) prairie plant mixtures; (b) the recommendation made by Arkansas researchers that broadcast establishment for crimson clover appeared to result in less establishment risk than no-till drill establishment, but the opposite was true for white clover; (c) a systematic survey by Minnesota and Wisconsin researchers for farm utilization practices of kura clover in Minnesota, Wisconsin and Iowa.
  4. The mathematical model (Gompertz equation) developed by NCCC-31 researchers is applicable for predicting pasture mass growth under a wide array of management scenarios. It validates recommendations for the monitoring of forage mass by producers (e.g., with a rising plate meter). The model has been presented to three grazing meetings within USA during 2011 and will be incorporated into future advanced grazing workshops. A related article has been published in Agronomy Journal.
  5. NCCC-31 researcher in Mandan, ND led a national multi-agency effort in the development of a literature synthesis summarizing the science behind the conservation practices applied to pasture and forage lands. Facilitated by the American Forage and Grassland Council (AFGC), the result of this synthesis will be published as a book in the third quarter of 2012 (will also be available electronically).
  6. NCCC-31 researcher in Wyoming selected well-adapted high performing accessions/lines of various legumes for the development of cultivars that will be specifically suitable for Wyoming and neighboring states. This will eventually contribute to the improvement of productivity of local and regional producers and in the long-run, with potential economic benefits.
  7. Responses of managed grasslands and pasturelands to future climate changes involve the interactions of multiple factors with complex feed-back/feed forward mechanisms. A clear understanding of the responses of grassland to changed climate scenarios is needed for both agricultural planning for environmental sustainability. A study by NCCC-31 researcher in the mesic grassland in Kentucky suggests that a 3 oC increase in air temperature is likely to reduce soil carbon storage and flux, but this effect may be offset or reversed if increased growing season precipitation occurs concurrently.
  8. Glyphosate-resistant (GR) alfalfa offers growers new options for weed control in alfalfa. A study by NCCC-31 researcher in Michigan cautioned that weed removal does not always result in improvement of relative feed quality or stand persistence of established glyphosate-resistant alfalfa. The study also demonstrates the improved relative forage quality of GR alfalfa under a high-intensity harvesting system (4 to 5 harvests yr-1) than it was with a moderate intensity harvesting system (3 to 4 harvests yr-1).
  9. NCCC-31 researchers in Arkansas demonstrated that much of the negative effect of the toxic endophyte on cow-calf production could be alleviated by using fall calving instead of spring calving, and (or) by replacing a limited amount of the access time to tall fescue with nontoxic (novel)-endophyte tall fescue during the critical breeding period.
  10. Extending grazing season‘s length and lowering the cost of grazing management are among the perennial quests by ranchers. NCCC-31 researcher in West Virginia has demonstrated the potentially negative impact of early-spring grazing under rotational stocking on subsequent pasture productivity, as well as the potential for beef heifers to feed themselves for part of the winter on pastures with stockpiled forage, thereby reducing costs associated with producing and feeding hay.
  11. Despite its popularity as an innovative pasture management system, mob grazing and its pros and cons remain to be largely anecdotal. NCCC-31 researchers in Kansas, Iowa and Nebraska are pursuing science-based answers to this problem through systematic studies taking into consideration soil and animal health, range sustainability, environmental quality impacts and long-term economic profits.
  12. Studies by NCCC-31 researchers in both Nebraska and Kansas demonstrate the benefits of using dried distillers grains (DDG) supplementation to increase grazing gains for beef cattle/steers while decreasing the use of commercial N fertilizers or increasing N use efficiency. The Nebraska study also demonstrates that DDG supplementation can provide resistance to annual weed invasion to pastures.
  13. NCCC31 researchers in Utah provided direct economic impact in $ amount for cattle grazing on monoculture birdsfoot trefoil pastures (stocking density 2 steers per acre). Using average daily gains of 3 to 3.5 lbs./day, a 900 lb. spring-born steer grazing for 90 days from June through August would reach 1170 to 1215 lbs. Production costs on irrigated pasture estimated from Neibergs and Nelson (2009) are $158/head or $316/acre. These cattle may not grade choice, but will fetch an offsetting premium as natural pasture-fed beef. If these two steers are sold in September (at $90.40/cwt; Ellis, 2011), gross return per acre would be about $1800 less the investment in the steers. An alternative use of agricultural land in this region would be to raise 6 tons of premium ($225/ton) alfalfa hay/acre at a cost of $500/acre, for a profit of $850/acre.
  14. NCCC-31 researchers in Arkansas cautioned that benefiting from the N-fertilizer-sparing effect of pasture legumes requires diligence and long-term commitment by producers.
  15. Balancing agricultural production and conservation has always been an issue vexing both forage scientists and the general public. NCCC-31 researchers illustrated this balance using context specific studies. One study in Iowa demonstrated through an economic budget model-based study that grazing prairie is most profitable for grazers when a rental rate is offered by land owners to provide a service of disturbance to the prairie. One study in Wisconsin highlighted the significant benefits of using kura clover living mulch and winter rye to reduce soil erosion and nutrient runoff in corn silage production.
  16. Using molecular biology techniques, NCCC-31 researcher and graduate student in Maryland detected a myriad array of salivary enzymes in the sialotranscriptome of the potato leafhopper grazing on alfalfa. As the first comprehensive study of the salivary components of the potato leafhopper, this work will allow others to build on further studies on how individual saliva components incite plant wound responses.
  17. Responding to society‘s needs for science-based evaluation of the economic and environmental feasibility of using cellulosic feedstocks for biofuels, NCCC-31 researcher in Indiana provided the first comprehensive economic and lifecycle analysis on corn stover, Miscanthus and switchgrass for biofuel conversion costs, considering both biochemical and thermochemical pathways. The study is expected to inform decision-making for future biofuel policies.
  18. There is possibility of increasing the carbon sequestration potential of mature pastures through nitrogen fertilizer application. However, NCCC-31 researcher in Pennsylvania found from a 3-year study that the applied N fertilizer boosted both the gross primary productivity and ecosystem respiration, resulting in no change in net ecosystem carbon exchange.
  19. Soil respiration partitioning is a critical step for understanding the regulation mechanisms of carbon flux from forage production systems but is prone to errors if using directly measured respiration rates from the field plots. NCCC-31 researchers in Pennsylvania and North Dakota conducted successful respiration partitioning in their respective forage systems, using natural abundance of 13C signature between C3 and C4 plant species and the field trenching plus modeling methods, respectively.
  20. Alfalfa winter survival continued to be the research focus of NCCC-31 scientists. Researchers in Minnesota and North Dakota are testing modern alfalfa varieties in order to establish updated recommendation for alfalfa winter survival. By relating alfalfa taproot C and N reserves and gene expression to the influence of P and K fertilization, researchers in Indiana help to deepen our understanding of the "secret" of eco-physiological mechanisms of alfalfa winter survival and yield persistence.
  21. NCCC-31 researchers have identified and illuminated a number of ecophysiological mechanisms underlying droguht stress responses and adaptations of major forage/bioenergy crops. Examples include (a) the molecular marker-based analysis to screen drought resistance genes in tall fescue (Wyoming/Oklahoma); (b) the study to further test the benefit of fungal endophyte symbiosis in tall fescue‘s response to climate change and abiotic stresses (Kentucky); (c) the analysis of season-long water and N use efficiencies for bioenergy sorghum production as influenced by land use change (Indiana); (d) the study to compare drought strategies of selected native and invasive grasses in terms of biomass partitioning (North Dakota/Minnesota); and (e) the study to increase pasture drought resistance through managing plant diversity (Pennsylvania).
