Brief Summary of Minutes of Annual Meeting

Minutes of annual meeting (recorded by Xuejun Dong): Ecophysiological Aspects of Forage Management Time: Wednesday, March 30, 2011 to Thursday, March 31, 2011 Place: Becker Center of Agriculture, Purdue University, West Lafayette, IN Wednesday, March 30, 2011 8:20 a.m. Chair Bill Lamp called meeting to order Ø Introduction Ø Welcome remark by Linda Lee, Associate Head, Department of Agronomy, Purdue University Ø Administration update by Jim Kells: Jim said that this is his second meeting to NCCC31. The project has been renewed and good for 5 years. There is requirement for mid-term report, but this year will be an easy year for the group. Jim reminded the group to submit the annual report within 90 days following the meeting. He also pointed out that if the next meeting is going to be held out of the region (North-central regions), a strong justification is needed for doing that. Ø Bill Lamp appointed the following personnel to serve on respective committees: ü Location committee: Mark Sulc, Anowar Islam, and Francisco Contreras ü Nomination committee: Paul Peterson, Joe Mayer, and Tom Griggs ü Resolution committee: Ken Albrecht, Ben Tracy, and Marvin Hall Ø Other discussions: ü Jeff Volenec indicated that he has been serving on the NCCC31 group for 30 years and happy to see its continued growth ü Bill Lamp suggested to recruit more female members (now there three of them); Linda is the contact person for updating names ü Jeff Volenec suggested to consider recruiting new members from 1890 schools to increase diversity ü Bill Lamp said he would like to contact Vance Owen (SD) and John Grabber (WI) to come back to the annual meetings ü Jim Kells reminded the group that new faculty members are encouraged to join NCCC31, but there is only on official representative for each state State reports Ø 9:00 a.m Wisconsin: Ken Ablbrecht highlighted an ongoing research entitled Stocker steer performance on tall fescue and meadow fescue with nitrogen fertilizer or in mixture with white clover. The purpose was to gain information on livestock performance on tall fescue and meadow fescue pastures and to determine the role that white clover can play as a replacement of N fertilizer. Data collected started 2010 and the experiment will run through the 2012 growing season. Ken also outlined several completed studies including applying kura clover living mulch in corn production. Ø 9:23 a.m. New Mexico: Francisco Contreras reviewed main issues in forage research in Southeastern New Mexico. Several completed/ongoing projects were highlighted: (a) in using warm-season annual legumes for forage production, it was found that lablab performed better than cowpea in Southern high plains by providing higher dry matter yield and nutritive value; (b) winter small grains for silage can be harvested at soft dough maturity stage without affecting significantly nutritive value, and barley and winter wheat had better nutritive value than winter triticale; (c) first year data of alfalfa samples were used to calibrate PEAQ and indicated usefulness in predicting alfalfa nutritive value in southwest USA. Ø 9:42 a.m. North Dakota: Xuejun Dong reported an ongoing greenhouse study comparing the effect of drought on biomass partitions between two introduced grasses (Kentucky bluegrass and smooth brome) and two native grasses (western wheatgrass and green needlegrass), suggesting that under drought stress the biomass investment to roots decreased in two introduced grasses but increased in two native grasses. However, drought responses in biomass investment in belowground rhizomes and shoot base (crowns) are similar between the two groups of grasses. He also reported his effort of summarizing CO2 flux from managed U.S. grasslands, suggesting a tight linkage between CO2 source/sink strength and precipitation. Ø 10:20 a.m. West Virginia: Tom Griggs reported an ongoing study on impacts of winter grazing and hay feeding on the reproductive performance of heifers in West Virginia. This is an intensively managed grazing system over the year-round grazing cycle on a perennial cool-season pasture considering animal performance and herbage production. A higher fall ADG was obtained under higher herbage allowance treatment, compared with lower allowance one. However, there was limited impact of herbage allowance on herfer reproduction performance. In addition, the common winter grazing season and intake compensation in following spring and summer grazing may have diluted the effect of herbage limitation in prior season on AGD and animal reproduction. The work illustrates the role of proper growing season pasture management and stockpiling for winter-season hay feeding, which can reduce the cost of winter feeding. Ø 10:45 a.m. Pennsylvania-PSU: Marvin Hall introduced the newly built biomass harvester at Penn state University- College of Agriculture. Enabled with a weigh system and able to harvest an 8 ft wide swath of tall grasses, the harvester has the maneuverability of harvesting small biomass plots for reducing variability in the research and maximizing the ability for detecting treatment effects. Marvin also introduced several other ongoing studies including (a) a warm-season grass production trial on abandoned strip mines in order to increase land productivity while improving the environment; (b) using slow release nitrogen fertilizer for orchardgrass; (c) determining the cost of delaying spring cool-season grass harvest; and (d) the evaluation of a portable NIR instrument for rapid monitoring of forage quality. Ø 11:05 a.m. Pennsylvania-USDA: Howard Skinner reported an ongoing study on the effect of nitrogen fertilizer application on net ecosystem exchange (NEE) from two long-term maintained perennial pastures in Pennsylvania. Past 6 years of data suggests that the pasture was almost carbon neutral. However, with nitrogen application in 2009 and 2010 at a rate of 200 kg N/ha/yr, both gross production and ecosystem respiration increased, but the former increased more, enabling the fertilized pasture to change from a slight carbon source of 33 g CO2 m-1 yr-1 to a net sink of -101 33 g CO2 m-1 yr-1. The study is to be continued for another year. Ø 11:25 a.m. Indianna: Jeff Volenec updated study trials on miscanthus, switchgrass, and sorghum. Sorghum has remarkably higher nitrogen use efficiency than miscanthus. Sorghum also has high water use efficiency and high heat tolerance. Jeff also introduced a project of water quality study: productivity and environmental impact of US cropping systems and heighted the trade-off between increased crop production and reductions in environmental pollution. Water use efficiency is a major issue, with higher biomass closely scaling with high water use; to a large extent, energy problem is a water problem. Finally, the ongoing studies at his lab are integrating experimental data with modeling and scaling field plot data to landscapes. Ø 1:00 p.m. Michigan: Jim Kells and Rich Leep gave a report entitled Effect of weed management following round-up-ready (RR) alfalfa stand establishment on forage productivity and stand longevity. The field treatment was started on August 13, 2003 by applying glyphosate and hexazinane (Velpar). The weed removal had positive effect (???) on forage quality, but did not impact stand persistence. Can continued weed removal from established alfalfa increase the productive life of the stand? The answer from this study is probably NOT. Ø 1:20 p.m. Wyoming: Anowar Islam highlighted his field trail of evaluating Fenugreek (Trigonella foenum-graecum L.) in Wyoming. Aside of its values as food ingredient with multitude of health benefits, Fenugreek has high nutritive value at all growth stages and does not create the bloat problem. As a result, it is potentially an attractive forage crop. Unfortunately, information on its cultivation in central high plains of Wyoming is lacking. In 2010, a trial was setup in two locations in Wyoming by planting seeds of 13 genotypes/accessions collected from Canada. The plants were gown under both irrigated and dryland conditions. Preliminary data in 2010 give information that lines F80 and IT give higher forage yield under irrigated and dryland condition, respectively. Anowar also introduced his cool-season grass trials under irrigation and dryland condition, as well as the first year result of the tall fescue-alfalfa mixtures in Wyoming, which suggest that 0.5/0.5 [all fescue/alfalfa] mixture gave the highest production in 2010. Ø 1:50 p.m. Maryland: Bill Lamp reported his studies using molecular biology techniques to further our understanding of biochemical mechanisms involved in potato leafhoppers feeding on alfalfa plants. By sequencing the salivary gland transcriptome of potato leafhoppers, his research group found that the leafhoppers saliva contains some important enzymes with anti-microbial and anti-oxidant properties, and those that can break down cellulose and starch into small molecules. This provide basis for further testing of the roles that different enzymes play in plant wound responses known as hopperburn. Another related study tested the effect of late injury of leafhopper on nitrogen fixation of alfalfa plants. It was found that later injury did not impact biomass accumulation, but did have reduced nitrogen content of alfalfa leaves. Furthermore, an ongoing study has used antibiotics to effectively manipulate salivary gland symbionts level in order to further study the alfalfas response to leafhopper feeding. Ø 2:10 p.m. Kansas: Joe Moyer reported an ongoing study of dried distillers grain (DDG) supplementation to grazing cattle in smooth bromegrass pastures. The purpose is to see if delayed DDG supplementation until forage quality declines can improve its effectiveness. Results show that both full grazing phase and delayed supplementations resulted in higher grazing gains, compared with no supplement. Compared with full supplementation, delayed supplementation resulted in deceased DDG intake. Although steers received no supplementation in 2009 had higher finishing gains than those with supplementation while grazing, data of 2010 suggest that steers with DDG supplementation had higher overall gains than those without supplement during the grazing phase. Joe also reported on a project of establishing legumes in grass pastures. Ø 2:25 p.m. Minnesota: Paul Peterson reported research results on alfalfa/tall fescue mixtures. Data of 2001 indicate (a) alfalfa was more dominant, but tall fescue came up later in the season; (b) 0.25 alfalfa/0.75 tall fescue mixture would give 0.5/0.5 dry matter yield. Paul raised a question of whether to use visual or hand sorting to separate grass, legume and weed components upon harvesting in the tall fescue-alfalfa mixture common experiment. He also updated an alfalfa/grass mixture trial at 3 locations in MN with four harvests. Ø 3:10 p.m. Virginia: Ben Tracy reported studies on biodiversity in native warm-season pastures (NWSP). The main aims are to test the biodiversity-productivity relationship, as well as the complementary effects of C3 and C4 species due to their differences in biomass peak growth. Results show that increasing sown NWSP diversity leaded to (a) higher forage yield and cover, (b) lower weeds cover and weeds richness, (c) lower CP but higher NDF and ADF. Grazing tended to increase amount of weeds and may reduce NWSP forage production. The effect of biodiversity of productivity was separated into selection effects (SE) and complementarity effects (CE). Three years data indicate that CE and SE can dominate in different years depending on climate and species succession. Ø 3:35 p.m. Ohio: Dave Barker reported a study using modified Gompertz equation to predict pasture mass accumulation. The key eco-physiological issue here is the proper canopy measurement to optimize digestible dry matter accumulation in pastures. Various field measurements, such as weekly monitoring of herbage mass using rising plate meter, forage quality, as well as morphological composition of the sward (stems, leaves, dead materials, etc.), conducted in both Ohio and Wisconsin, were used to support this modeling work. Furthermore, by analyzing the fitted curves, the range of total available herbage biomass corresponding to the maximum instantaneous herbage growth rate can be determined. Ø 4:06 p.m. Arkansas: Chuck West reported a study on switchgrass growth simulation, responses to nitrogen, and use in cotton intercropping. The main effort was to calibrate the ALMANAC model for use in switchgrass. The model simulates N, P, K, and water dynamics, as well as ash, and total energy. It has a fully functional web support and can be easily downloaded. One can specify exact county location (in USA), crop type, management (grazing, fertilization, etc.), and nearest weather station. Chuck and his group are also conducting further development to expand the models capability. Thursday, March 31, 2011 8:00 a.m. - 10: 30 a.m. Committee reports and discussion lead by Bill Lamp Ø Committee reports ü Location: Mark Sulc represented location committee (Mark Sulc, Anowar Islam, and Francisco Contreras) to suggest Minnesota as next meeting place; members suggested to meet in June (specific dates to be decided later). All agreed on the location committees suggestion. Paul Peterson agreed to serve as local host in the next meeting and he suggested St. Paul campus as het meeting place. ü Nomination: Paul Peterson represented nomination committee (Paul Peterson, Joe Mayer, and Tom Griggs) and suggested to appoint both the next chair and next secretary. Jim Kells mentioned that this will be an easy year to serve as chair and encouraged members to volunteer. Following a brief discussion, Xuejun Dong was appointed as next chair, and Marvin Hall as secretary. As usual, the secretary is to be the chair in the following year. All supported the two nominations and both Xuejun and Marvin agreed to serve. ü Resolution: Marvin Hall represented resolution committee (Ken Albrecht, Ben Tracy and Marvin Hall ) to make the following resolution statements: " Whereas members of the NCCC-31 committee enjoyed a stimulating exchange of information and ideas on 29-31, March 2011 at the excellent meeting facilities at Purdue University; be it hereby resolved that we are deeply grateful to Jeff Volenec for making local arrangements. " Whereas Rich Leep has been a faithful member of the NCCC-31 committee for nearly 15 years and whereas Rich has announced his impending retirement; be it hereby resolved that the members deeply appreciate Richs scientific contributions, excellent leadership, and professional fellowship over the years. The resolutions were approved unanimously. Ø Discussion ü Jim Kells pointed out that there will be a mid-period report for this group, which is one year from now. Regarding the annual report, Jim reminded the members that the annual report contains only a synopsis of the report for each state, and that the longer one (full report) is not for official report. Chuck West suggested that the longer report is not to be posted on public domain either. ü Ben Tracy lead a discussion with six other members (Bill Lamp, Anowar Islam, Ken Albrecht, Paul Peterson, Howard Skinner, and Xuejun Dong) to update sampling protocols for the alfalfa-tall fescue common experiment, for which there are eight participating locations within the NCCC31 group (Jennifer MacAdam was not able to come this year at Purdue). After a discussion, it was agreed that hand sorting (instead of visual sorting) is to be used to separate groups of plants upon harvesting, and a complete set of data from all sites for one year (in 2011) will be used to write an article, while beyond that, additional data collections for further collaborations are encouraged. Ben said he would send updated experimental protocols and procedures to participating members soon following this meeting. ü Bill Lamp lead a discussion to familiarized the members with the functionality of the NIMSS website, featuring the NCCC31 group. Bill emphasized that in addition to routine documentation of meeting activities, the website also shows the money devoted to this groups activity (professional year allocation for each member). The photo album located on this website can be used to post relevant pictures, or slide series that have public education value, or can be used by ourselves. ü Chuck West lead a discussion on the regional integrated CAP proposal, for which participating members had discussed on March 29, 2011 at the same location at Purdue before the main NCCC31 meeting. This planning proposal had also been discussed among relevant members in the ASA meeting in Long Beach, November 2010. With input from NCCC31 members, Chuck updated and fine-tuned the match between main objectives and corresponding personnel/partners. Chuck also introduced a newly available online graduate course on agricultural sustainability lead by five institutions, of which he was part. He said that life cycle analysis is part of the online course, which emphasizes the relevant skills and knowledge base for farm sustainability. ü Jeff Volenec introduce the members a new web-based tool on nanotechnology called: NANOhub.org. It is tool and data oriented online simulation system (with > 160 tools, including those relevant to agriculture). Also, it includes various courses useful for agronomy and agriculture. ü Bill Lamp reminded the group that this year there is a new NNF graduate program that has focus on integrated training in multi-disciplinary aspects, with a deadline line of June 1. With multiple institutions, each of them can submit separately with one institution leading. Jeff Volenec said he would send to the group a copy of his proposal as a sample. Ø 10:30 a.m. Meeting adjourned

As this is the first year of our renewed project, accomplishments are few. We are planning for submission of a major grant proposal, and obtained funding for the planning process. In addition, we are meeting with producer groups and organizations to find out their perspectives on climate change, and their anticipation of information needs in the future. Our research also builds on past accomplishments as identified in the impact statements below.
