Last week we held a field research symposium and annual meeting in Stillwater. I particularly thank Rick Todd and the field research group for organizing and presenting their research results and conclusions. Also, thanks to our OSU partners for hosting us. It was really a nice summer break and I am even more confident that our research and extension work will make a real difference!
During the meeting we heard a very positive report from our external evaluators. We are proud of our successes and are taking steps to address the challenges remaining. As we wrap up our third year of funding we are preparing to submit our year 3 progress report and anticipate confirmation for year 4 funding in the near future. We are excited to move forward with project research and activities.
Please contact me if you have any questions.
The inaugural Great Plains Grazing Research Symposium included presentations from field research scientists and graduate students on soil greenhouse gases, methane emissions from grazing systems, and strategies for adapting beef cattle production to varying conditions. Thanks to all who contributed your research. Papers included in the proceedings document are listed below.

Intuitive Assessment Aids Stocking Rate Management
June 2016 - Ag News and Views
A producer with several years of experience with a property can make a determination on whether or not adjustments to the long-term stocking rate are needed by using his or her own intuition and observations.

Dewpoint, Dryline and Storms
May 13, 2016 - Weather & Agriculture: A Plains Perspective
So when you think about air moisture do you think dewpoint or relative humidity? Get a group of meteorologists together and they’ll soon bring up dewpoint temperatures and its role in severe storms. Get a group of farmers together and they’ll fill you in on how they watch relative humidity for baling hay and prescribed burns.

Potentially Toxic Forage Crops for Cattle
1:30pm(CT) - June 28, 2016
Growing cover crops offer potential benefits, including improved soil health, but some of these crops can pose a danger to foraging livestock. Those contemplating this decision should know that lants that work well as cover crops may not be suitable for forage or grazing.
Great Plains Grazing team member and Kansas State University southeast area extension beef systems specialist Jaymelynn Farney will present “Potentially Toxic Forage Crops for Cattle Producers,” a free webinar at 1:30 p.m. (CDT) on Tuesday, June 28. The webinar is open to anyone interested in gaining a better understanding of how cover crops can fit into a livestock grazing system.
Webinar participants can expect to learn:
- dangers associated with grazing some cover crop species
- ways to mange potentially toxic forage crops
Farney is based at K-State’s Southeast Agricultural Research Center in Parsons. She grew up in Fort Sumner, New Mexico where her family had a cow-calf operation. She completed her associate’s degree in agriculture from Butler Community College where she was a member of the livestock judging team and then continued her education at Kansas State University in animal science. Jaymelynn then went to Oklahoma State University to complete her master’s in ruminant nutrition with an emphasis on receiving calf management. She returned to K-State to complete her Ph.D. in ruminant nutrition, using the dairy cow as the model for how inflammation impacts production.
Farney’s research interests include alternative forages and management practices to improve cowherd efficiency. She is involved in the Sunflower Supreme Replacement Heifer Program which has developed protocols for replacement heifer development to help with breeding and calving ease.
The webinar series aims to provide research-based information, and is targeted for producers and extension agents. Previous webinars are archived and more information is available at http://www.greatplainsgrazing.org/ .
