Largest crowd ever turns out for Ag Day 2013 festivities

May 2, 2013 under CANR News

Ag Day Bird showBeautiful weather, great entertainment and a variety of agricultural and environmental exhibits combined to make Ag Day 2013 the largest in history, with more than 8,000 visitors in attendance.

The record crowd of visitors gathered at the 38th annual Ag Day were able to see over 90 interactive exhibits and witness a variety of demonstrations including a beehive demonstration, a free flight bird show, a Seeing Eye dog demonstration, a tree climbing exhibition, live bands featuring University of Delaware faculty and professionals, and the unveiling of a portrait of Robin Morgan, former dean of the College of Agriculture and Natural Resources (CANR).

New to Ag Day this year were horse-drawn wagon tours of the UD farm put on by Circle C Outfit from Bridgeville, Del., which featured Rick, one of the horses from UD’s herd.

Always popular at Ag Day are the many plant sales by the University of Delaware Botanic Gardens (UDBG), UD Horticulture Club and New Castle County Master Gardeners, and the ice cream from the UDairy Creamery. This year the UDairy Creamery sold ice cream to over 3,600 patrons, practically doubling the amount that they sold at Ag Day 2012.

Also popular was the free flight bird show, which is put on by a CANR alumnus. “One of the unique things that we’ve been able to offer the past few years is we have an animal science alum who does animal training and behavior, who travels around the U.S. to train educators to conduct live bird shows,” explained Katy O’Connell, communications manager in CANR. “At Ag Day, he offers two free flight bird demonstrations where he has macaws, vultures, hawks and even chickens that he trains to do live demonstrations.” The crowd for the 2 p.m. showing topped 500 audience members.

CANR Dean Mark Rieger, having been hired in August 2012, was on hand for his first Ag Day and welcomed those in attendance, saying, “We hope that you learn something about agriculture, and we also hope that you learn something about natural resources — that’s the other part of our name. If you take the farm tour and you go on the carriage ride, you’re going to see wetlands, you’re going to see streams, you’re going to see woods, you’re going to see songbirds. If you go inside, you’re going to have a wildlife display in there, an entomology display, and things like that. So there’s a lot of different things here today; make sure you get around and see all those things.”

Rieger also thanked O’Connell, who led the organization of the event, along with eight undergraduate students, Kim Yackoski, CANR assistant dean, and Latoya Watson, CANR academic adviser, before handing the microphone over to Tom Sims, CANR deputy dean, who had a special presentation for Morgan.

Robin Morgan’s portrait

The portrait — a CANR tradition that sees each dean get their portrait painted and hung in Townsend Hall — was unveiled by Rieger and Sims.

Of Morgan, Sims said, “It was my privilege to work with [Morgan] as associate dean and deputy dean for nine years. She really was committed to our students, our undergraduate students, she was committed to our faculty, she built our faculty by hiring many of our current faculty members and was committed to agriculture and natural resources as she demonstrated throughout her tenure as dean.”

After unveiling the portrait, painted by Kellie Cox, a UD alumna, Sims continued saying, “This is just a small way of saying thank you to Robin for all that she’s done. She’s now back on the faculty getting ready to teach a big class this fall so her commitment to agriculture and our students just goes on and on.”

Rieger echoed these sentiments adding, “I want to thank Robin for coming out today and all the things that she did for the college. It makes my job a lot easier having to step into her shoes when she has done so much for the College of Agriculture and Natural Resources.”

Soil may harbor answer to reducing arsenic in rice

May 1, 2013 under CANR News

Drs. Harsh Bias & Janine Sherrier work together with bacteria resistant rice plants at the Greenhouse.Harsh Bais and Janine Sherrier of the University of Delaware’s Department of Plant and Soil Sciences are studying whether a naturally occurring soil bacterium, referred to as UD1023 because it was first characterized at the University, can create an iron barrier in rice roots that reduces arsenic uptake.

Rice, grown as a staple food for a large portion of the world’s population, absorbs arsenic from the environment and transfers it to the grain. Arsenic is classified as a poison by the National Institutes of Health and is considered a carcinogen by the National Toxicology Program.

Long-term exposure to arsenic has been associated with skin, lung, bladder, liver, kidney and prostate cancers, and low levels can cause skin lesions, diarrhea and other symptoms.

The risks of arsenic in rice were recently highlighted in the national press, when arsenic was detected in baby foods made from rice. In regions of the world where rice is the major component of the human diet, the health of entire communities of people can be negatively impacted by arsenic contamination of rice.

Arsenic may occur naturally in the soil, as it does in many parts of Southeast Asia, or it may be a result of environmental contamination. Despite the health risks arsenic in rice poses to millions of people around the world, there are currently no effective agricultural methods in use to reduce arsenic levels.

Sherrier, professor, and Bais, associate professor, are investigating whether UD1023 — which is naturally found in the rhizosphere, the layer of soil and microbes adjacent to rice roots — can be used to block the arsenic uptake. Bais first identified the bacterial species in soil samples taken from rice fields in California.

The pair’s preliminary research has shown that UD1023 can mobilize iron from the soil and slow arsenic uptake in rice roots, but the researchers have not yet determined exactly how this process works and whether it will lead to reduced levels of arsenic in rice grains.

“We have a bacterium that moves iron, and we want to see if creating an iron shield around the rice roots will slow arsenic movement into other parts of the plant,” Bais said.

Sherrier and Bais, who received a 2012 seed grant for the project from Delaware’s National Science Foundation Experimental Program to Stimulate Competitive Research (EPSCoR), ultimately want to determine how UD1023 slows arsenic movement into rice roots and whether it will lead to reduced levels of arsenic in the rice grains, the edible portion of the plant.

“That is the most important part,” Bais said. “We don’t know yet whether we can reduce arsenic in the grains or reduce the upward movement of arsenic towards the grain, but we’re optimistic.”

Bais says that, if successful, the project could lead to practical applications in agriculture.

“The implications could be tremendous,” he said. “Coating seeds with bacteria is very easy. With this bacteria, you could implement easy, low-cost strategies that farmers could use that would reduce arsenic in the human food chain.”

Rieger, Rodgers and Allen attend rural economy summit in Washington

May 1, 2013 under CANR News

Chris Coons talks with Mark Rieger, Michelle Rodgers and Melanie AllenMark Rieger, dean of the College of Agriculture and Natural Resources (CANR), Michelle Rodgers, associate dean and director of University of Delaware cooperative extension, and Melanie Allen, a senior studying wildlife conservation in the Department of Entomology and Wildlife Ecology, recently participated in a half-day summit on issues of importance to rural communities across the nation. The event featured U.S. Senator Chris Coons (D-Del.), and was hosted by the Senate Democratic Steering and Outreach Committee and featured two moderated panels focused on rural economics, infrastructure, and access to critical services.

The panel highlighted the economic conditions facing rural communities and the agriculture industry, and what role the federal government can play in ensuring long-term support for the communities. Issues discussed during the summit included the importance of investing in the health of farmland, natural resources, and infrastructure. Another topic of discussion was connecting farmers and ranchers with consumers, including individuals, schools, hospitals and businesses.

“Our rural communities are central to our identity, our economy, and our values,” said Coons. “Between our agriculture sector, environmental conservation, and tourism, it’s no surprise that Delaware’s rural communities are thriving. It’s important that we continue to facilitate an open dialogue between our rural communities and our elected officials to ensure we aren’t hindering their growth and development. I thank the members of the University of Delaware for attending today’s event and sharing their views on how we can strengthen our state’s rural areas.”

More than 200 rural development advocates attended the summit.

Arthritis and Agriculture

April 25, 2013 under CANR News

Arthritis affects approximately one-third of all adult farm operators and is considered one of the leading causes of disability by customers of the USDA AgrAbility Project. With the average age of the American farmer now above 57, increasingly more farmers will find the tasks difficult to complete. For example arthritis can cause significant impairments to one’s mobility, dexterity, capacity to lift heavy loads and emotional well-being due to unmanaged pain and other factors.

Arthritis is an umbrella term for more than 100 diseases that can affect the joint and surrounding tissue. Common forms of arthritis include osteoarthritis, rheumatoid arthritis, osteoporosis, gout, and fibromyalgia.

Arthritis is considered one of the most disabling conditions a farmer can face and is the leading cause of disability of farmers in the Mid-Atlantic area. Arthritis affects approximately one-third of all adult farm operators. As work tasks become more difficult, many farmers and agricultural workers may not even associate the pain with arthritis. Signs and symptoms of arthritis include the following:

  • Persistent pain
  • Stiffness, swelling, redness or heat in the joint
  • Difficulty in moving the joint
  • Possible fatigue, weight loss and nausea

Arthritis is especially detrimental to farmers and farm workers because of the nature of their work. Many farm chores such as mounting tractors, baling hay, feeding livestock, harvesting vegetables, milking cows, operating equipment, cleaning out broiler houses require strength, dexterity, and mobility, which are lessened by the effects of arthritis.

According to medical professionals there are benefits of exercise for farmers with arthritis. Exercise can help you manage arthritis pain and reduce the disability as well as increase energy levels, help with sleep and decrease depression and fatigue. Exercise is also considered very important for healthy joints. Moving your joints helps keeps them fully mobile and strengthens the surrounding muscles which help support the joints.

Since there is no known cure for arthritis, education and awareness of pain management techniques are considered the best practice for treating the disease. This includes but is not limited to joint protection, work simplification and stress reduction. A few solutions that can be implemented to help control joint stress and pain in farming include the following:

  • Wear quality, non-slip footwear
  • Use appropriate assistive aids such as automatic couplers, mobility devices, hydraulic lift table, shop hoists, powered cordless caulk guns and more
  • Adhere to proper posture when sitting for long periods of time in tractors
  • Use large muscle groups to complete a task. For example use the legs instead of the back to lift.
  • Avoid gripping and grasping for long periods of time.
  • Simplify jobs and tasks
  • Pace yourself throughout the day

Arthritis is a debilitating disease, but it is manageable. You will be able to farm productively and safely. The Mid-Atlantic Agrability Project and the Arthritis Foundation are willing to help in any way that they can. They promote technologies and given your tenacity and willingness to try, you can preserve your livelihood on the farm.

For more information on arthritis please visit Mid-Atlantic Agrability on the web at www.mid-atlanticagrability.com or visit the Arthritis Foundation at www.arthritis-ag.org.  You may also call Mid-Atlantic Agrability toll free at 1-877-204-FARM (3276) for a DVD titled Gaining Ground on Arthritis in the Agricultural Workplace and a brochure titled “Arthritis and Agriculture”.

Animal Science Club to screen the film “Temple Grandin”

April 25, 2013 under CANR News

The Animal Science Club will host a viewing of the award winning HBO film Temple Grandin on Wednesday, May 1, at 5:30 p.m. in 006 Kirkbride Hall. The film stars Claire Danes as Temple Grandin, and portrays the early life and career of Grandin, the challenges she faced and her accomplishments as a young woman growing up with autism.

Grandin is a professor of animal science at Colorado State University. She teaches courses on livestock behavior and facility design and consults with the livestock industry on facility design, livestock handling and animal welfare. She has designed livestock handling facilities located in the United States, Canada, Europe, Mexico, Australia, New Zealand and other countries.

Nearly half of the cattle in North America are handled in a center track restrainer system that Grandin designed for meat plants. Her research interests include cattle temperament, environmental enrichment for pigs, bull fertility, training procedures, and effective stunning methods for cattle and pigs at meat plants.

Grandin has authored several books including: Thinking in Pictures, Livestock Handling and Transport, Genetics and the Behavior of Domestic Animals, and Humane Livestock Handling. Her books Animals in Translation and Animals Make Us Human were both on the New York Times best-seller list.

The film will be introduced by Carissa Wickens, assistant professor in the Department of Animal and Food Sciences, who recently co-authored a chapter on horse handling and transport for Grandin’s 4th edition of Livestock Handling and Transport. Wickens also had the privilege of serving as a judge alongside Grandin during the Collegiate Animal Welfare Judging Competition held at Michigan State University in the fall of 2011.

UD team wins first place in East Coast regional Linnaean Games

April 23, 2013 under CANR News

Entomology Graduate student team won the east coast regional Linnaean GamesA group of four University of Delaware graduate students studying in the Department of Entomology and Wildlife Ecology bested teams from Penn State, Virginia Tech and the University of Maryland to win first place in a regional match in the Entomological Society of America’s Linnaean Games, a competition in which teams are quizzed on entomological questions.

Having won the East Coast regional competition, the UD team will head to Austin, Texas, to compete in the national competition in November.

Team members include Scott Berg, Ashley Kennedy, Kaitlin Handley and David Gardner, all master’s degree students, with Kennedy having just completed her program.

In the first round of the tournament, the team defeated Virginia Tech and later topped Penn State in the finals. Each round lasted about 20 minutes and consisted of 16 questions. If a team got an answer correct, they were given a bonus question.

While some of the other teams had coaches to help them prepare for the Linnaean Games, the UD team had no such help. “Some schools take it really seriously and every year they have coaches,” explained Handley. “This is the first year that UD put together a team and it was all Ashley’s doing.”

Even though the team didn’t have a coach, Kennedy was able to find something extremely helpful on-line that helped the team prepare for the competition — YouTube videos of past competitions. She transcribed the questions and the answers from those past tournaments and handed them out to her teammates.

Watching the videos of past tournaments, however, did have some consequences, as well, with team members getting a glimpse of just how challenging the questions would be. “Hearing some of the questions that Ashley transcribed and watching some of the videos, oftentimes, they’ll ask a question and neither team gets it and then they’ll just turn to the audience for fun and say, ‘Does anyone know it?’ and the audience is silent,” said Berg. “So we were thinking that this was going to be pretty tough. But the questions they had this year — I don’t know if it was just luck or what — but they seemed a little bit more manageable.”

Kennedy also explained that while the team didn’t have a coach, they didn’t consider themselves underdogs. “We did have more of an advantage than some of the other schools just because we do have a good variety of entomology classes here that cover all the basic areas.” 

Gardner, who is relatively new to the entomology field having studied behavioral neuroscience as an undergraduate, agreed with that assessment, saying that the entomology department at UD is “great. The professors are great, colleagues are great, everyone is really interesting, so I enjoy it.”

Winning the Linnaean Games was not the only prize the group took home from the conference as Berg also won second place in oral presentation.

The team is now looking forward to the national competition and attending the five-day conference, with the hopes of recruiting a coach to help them prepare.

Kennedy noted that Charles Bartlett, associate professor of entomology and wildlife ecology, has agreed to coach them prior to the national competition.

UD’s Allen travels to Ghana to conduct research, educate on water quality

April 22, 2013 under CANR News

As a wildlife conservation major, when University of Delaware student Melanie Allen got to travel to Ghana this past summer to conduct research, she was not expecting to be assigned to a project that looked at water quality.

“When I first got assigned to this project I was like, ‘What am I doing? I want to work with butterflies,’” said Allen, a senior studying wildlife conservation in the Department of Entomology and Wildlife Ecology in UD’s College of Agriculture and Natural Resources.

It turns out, however, that the project enriched her in ways she never would’ve experienced has she not stepped out of her comfort zone.

Allen first went to Ghana in the summer of 2012 to conduct water quality research on polluted lagoons in Cape Coast, located in the central region of the country, through a Research Experience for Undergraduates (REU) program at Virginia Tech.

UD student Melanie Allen traveled to Ghana for water quality researchAfter receiving an Honors Enrichment Award through the UD Honors Program (UDHP), she went back during Winter Session to learn more about the challenges to conservation facing developing countries. This involved educating the locals and making sure that they knew about the dangers of polluting, and the risks involved with eating fish found in the water supply.

During her first trip to the region last summer, Allen said that she realized the need to go back to the country because she was “doing water quality research in lagoons that are used for human consumption” and recognized a lack of communication between the people studying the high levels of pollution in the lagoon and the villagers who were using the lagoon on a daily basis.

Allen said it was clear that the people using the lagoon “weren’t really being informed of what was going on, why they shouldn’t pollute, why it’s dangerous for them to consume water or any fish from there.”

She wondered, “What’s the point of this if we’re just going to publish this paper and there’s not going to be any kind of implementation? That’s why I wanted to go back and work with a local organization that’s directly involved in those lagoons doing environmental education and public awareness activities.”

Working with the Center for Environmental Impact Analysis, a new and small nongovernmental organization (NGO), as its first international volunteer, Allen had two main tasks. The first involved creating a curriculum and engaging students from five middle schools in learning about pollution.

“One of [the center’s] goals is to inform the youth about all of these issues since they’re going to be the future leaders, so they established these environmental clubs in five different junior high schools two years ago,” said Allen.

She devised a curriculum for the students — one that she is still tweaking now that she is back in the United States — with chapters that provide overviews on different topics such as water pollution, climate change and waste management.

Allen explained that the chapters also had questions for the students and group activities that they could do, as well as “take home” messages so they could try to spread their knowledge to the older members of their families.

Allen also worked on a community cleanup at one of the lagoons that she had been studying on her previous trip to Ghana.

Instead of simply having a community cleanup, however, Allen used the opportunity to engage people who had different stakes in the lagoon, such as the local fisherman and the local waste management company that donated supplies to the cleanup.

Allen said that though they were trying to clean up the lagoon, the real purpose was to educate residents about the risks involved in pollution, as the water in the lagoon is probably too polluted for healthy use at this time. “There’s a hospital a couple of blocks away that dumps all their medical waste in there,” said Allen, “and all of the runoff from the street goes in there, so it was just more of a raising awareness activity, bringing everyone together and informing the public.”

Tying in her first project with her second, Allen also brought in two professors who had conducted research on the lagoon to speak with the locals. “They gave a presentation, releasing all of their data on what they found in the lagoon,” said Allen. “It really was this holistic approach to community development so that was really exciting for me to work with people that I worked with over the summer but in a different manner.”

After her experience in Ghana, Allen said that she is no longer looking at master’s programs that deal solely with wildlife conservation, but rather programs that incorporate both of her interests. “I’m looking at master’s programs that integrate the two — like sustainable development, human environment interactions, conservation biology — so I definitely want to do something where it involves international development with a focus on conservation. The trip really has shaped my future career goals completely.”

UD’s Sparks to chair national soil science committee

April 19, 2013 under CANR News

Donald SparksDonald L. Sparks, S. Hallock du Pont Chair in Soil and Environmental Chemistry at the University of Delaware, has been appointed to a three-year term as chair of the U.S. National Committee for Soil Science (USNC/SS).

From 1999 to 2008, he was an ex-officio member of the USNC/SS and has served as a full member of the committee since 2010.

The USNC/SS advises the National Academies on issues related to soil science and is also the formal representative of the U.S. soil science community to the International Union of Soil Sciences (IUSS). It provides input to the union on behalf of U.S. soil scientists, arranges for scientific meetings in the United States in consonance with the union’s objectives, and directs attention to soil science research needs.

“I am honored to serve as chair of the U.S. National Committee for Soil Science,” Sparks said. “Soil science is at the center of all the major global challenges we face today including water, land degradation, climate change, contamination and food security. As chair of the committee, I will work with my colleagues to promote the importance of soil and the discipline of soil science to the global community.”

“I cannot imagine a better lead representative of the U.S. soil science community than Don Sparks,” said Paul Bertsch, the outgoing chair of the USNC/SS and professor of environmental chemistry and toxicology at the University of Kentucky. “He is among the most respected soil scientists worldwide. He brings critical leadership skills along with a deep recognition of the primary international soil science societies as well as the most important issues surrounding this global resource.”

The USNC/SS is one of several U.S. national committees focused on specific scientific disciplines within the National Research Council’s (NRC) Board on International Scientific Organizations. The national committees as a whole perform the dual function of fostering U.S. participation in international science and fortifying communication linkages between the U.S. and international scientific communities.

In addition to addressing research needs in their respective fields, the national committees are encouraged to work together to identify areas where cross-disciplinary teamwork may be more effective.

In addition to Sparks, the USNC/SS is composed of 10 at-large members, six members representing various allied scientific societies, and several ex officio and staff members representing the National Academies, of which the NRC is one branch. All committee members must be approved by the chair of the NRC.

Sparks has been active in the international soil science community for many years. He served as the president of the IUSS from 2002–06 and past president from 2006–10. In 2010 he received that organization’s von Liebig Medal for his outstanding contributions to soil science research and, most recently, was elected an honorary member of IUSS.

Sparks is a fellow of the American Association for the Advancement of Science, the Soil Science Society of America, the Geochemical Society, and the European Society of Geochemists. He has also served as president of the Soil Science Society of America.

Sparks has been a faculty member in the Department of Plant and Soil Sciences in the College of Agriculture and Natural Resources since 1979 and served as chair of the department for 20 years. He was the first recipient of UD’s Outstanding Graduate Advising and Mentoring Award. In 1996, he received the Francis Alison Award, the highest academic honor bestowed at UD.
