Happy New Year!!! This week has been a good one to reflect on 2017.
It was a year of unusual situations such as the dry winter allowing for nitrogen burn on corn, herbicide carryover, wheat stem maggot in corn from late-terminated wheat/rye, dicamba concerns on soybeans/trees/vegetables, downed corn ears and the challenge of recovering them…I think so often as I reflect, it’s easy to see the problems that occurred as those tended to be the headlines.
But as I also reflect, I think of so much more. It’s been a hard several years both personally and professionally for me and one reason I love Extension is for the relationships I’m so blessed to have. As I reflect on this past year, it was a year of spending time sharing the ways we all were hurting/healing while looking at crop problems, working in on-farm research plots, or just visiting. It was a special year in building even deeper relationships with many of you whom I’ve served in the past and meeting new people in the area I’m serving. Thank you also for your grace as it is a challenge serving regions of counties. I truly am grateful for the friendships and opportunity to serve you!
One of my highlights was pesticide training…yes, pesticide training! I know it’s required for us as private applicators every three years, but it’s my chance to teach/learn from/see so many of you and do my best to share important crop information as well. I enjoy winter meeting time as it always feels like a big reunion to me to see who comes and to catch up! Pesticide training last year was fun to still have the opportunity to train those of you in my former area and meet many in my new area.
Another highlight is a group of youth I meet with each month for Crop Science Investigation (CSI). This was such a rewarding experience for me in Clay County working with Clay/Nuckolls county youth and watching them learn, grow, and some pursue ag careers through the years. In York County I’m blessed with a very young, energetic group of youth who are so much fun and love to learn! Basically, the youth are detectives every time we meet as I give them a real problem to solve. We spend time out in the fields learning about crop growth, weed/insect/disease ID, take industry tours, etc. Our youth right now are mostly in the 6-11 year old range but any youth and parents are welcome to join us if you’re interested. Please just let me know at firstname.lastname@example.org for meeting times.
On-farm research plots are always a highlight for me for how much can be learned and this year we had some intense plots regarding data collection! Grateful for the farmer-cooperators in the time spent on these plots and how you’re so good at working with me.
I also am grateful to the media. With fewer of us in Ag Extension, we’re called on more often to share when problems arise. So grateful for the relationships with all our media partners-TV, radio, newspapers, magazines-and all you do in helping us share our research-based information timely!
As I think about 2018, one concern continues to be low commodity prices and ways to make it through. The Farm Bill and what will happen regarding it is another topic. Dicamba unfortunately may continue to be a topic. And, it seems like every year we have varying weather that creates challenges and opportunities. Two things that will continue are the optimism/resiliency I see every year in our farmers and the strong family that Ag in general is. Here’s wishing you a safe and blessed 2018!
York Ag Expo: Reminder of the York Ag Expo January 10-11 at the Holthus Convention Center in York. A full list of exhibitors is available at: http://yorkchamber.org/yorkagexpo/.

Many stalks in Nebraska are left ungrazed for various reasons. One reason I’ve heard is the potential impact of increased compaction and reduced yield of the next crop. Nebraska Extension has long-term research addressing this concern…in fact, 16 years of research conducted at the Ag Research and Development Center near Mead. There’s various components to this study and you can view the full report at: http://go.unl.edu/8mp6.
In this study, cattle were allowed to graze corn residue in the spring (February to mid-April) or the fall (November through January) and these treatments were compared to an area not grazed. Corn and soybeans were planted the spring after grazing the residue for 16 years to determine the effect of grazing on the subsequent crop yield.
In the fall grazing treatments, the corn and soybeans were planted no-till. For corn or soybeans planted into the spring grazing treatments, three tillage treatments were also implemented for nine years: no-till, ridge-till, and spring conventional till, after which all treatments were converted to no-till. This result of the tillage by spring grazing treatments for either corn or soybean yield over nine years showed no interaction and suggested the same effect on yield regardless of tillage treatment used after spring grazing.
Spring grazing across all tillage treatments did increase soybean yields statistically (58.5 bu/ac for spring grazed vs. 57.0 bu/ac for ungrazed) and had no effect on corn yields. The results were similar looking at 16 years of grazing vs. not grazing under no-till for both corn and soybeans in the spring; there was no yield effect found for corn and the soybeans showed a slight yield increase with grazing.
Looking at a 10 year period of no-till management for both spring and fall grazed corn residue and subsequent corn and soybean crops, fall grazing statistically improved soybean yields over both spring grazing and no grazing (65.5 bu/ac vs. 63.5 bu/ac and 62.1 bu/ac respectively). No grazing effects were observed on corn yields in either season. All statistics were at the 95% confidence level meaning the researchers were 95% confident any yield differences were due to the treatments themselves vs. random chance.
Regarding compaction, in the fall, the field was typically frozen and the researchers felt any mud and compaction associated with grazing cattle was minimized; highest subsequent soybean yields were achieved with fall grazing. The spring treatment was designed to look more at potential compaction and muddy conditions after spring thaw till right before planting-thus the implementation of different tillage treatments as well. They used a stocking rate consistent with UNL grazing recommendations resulting in removal of half the husks and leaves produced (8 lbs of leaf and husk per bushel of corn grain produced). Results of this study indicate that even with muddy conditions in the spring, grazing increased subsequent soybean yields compared to not grazing regardless of tillage system used and that corn yields were not different between grazing vs. not grazing and regardless of tillage system used in the spring. This study was conducted in Eastern Nebraska in a rainfed environment with yields ranging from 186-253 bu/ac with a 16 year median yield of 203 bu/ac.
Additional Grazing Study
A five year fall grazing study (December through January) was conducted in an irrigated continuous no-till corn field at Brule, NE to determine the effect of corn residue removal via baling corn residue or fall grazing on subsequent corn yields. That environment receives limited rainfall and residue is deemed important for reducing evaporation of soil moisture in addition for catching/keeping snow on fields. Farmers were questioning the effects of any residue removal on subsequent corn yields and the study was implemented.
Treatments were 1) fall grazing at 1 animal unit month/acre (AUM), 2) fall grazing 2 AUM/ac, 3) baled, or 4) ungrazed. The researchers found that residue removal did not affect corn grain yields from 2009-2013 in the continuous corn rotation. There were no statistical yield differences with 5 year average yields of: 152 bu/ac, 155 bu/ac, 147 bu/ac and 148 bu/ac respectively for the above-mentioned treatments.
Radio advertisements, email blasts, and other media are warning of corn diseases and the need for fungicides. Two months of humid, wet weather has allowed for disease development. It’s important to know what diseases truly are in your field before spraying a fungicide, particularly with today’s economics. Here’s what we’re seeing in fields right now in the Clay, Nuckolls, Thayer, Adams county area. Based on the diseases we’re seeing, we would recommend you scout your fields to know whether you have mostly bacterial or fungal diseases present. Consider disease pressure, where on the plant the disease is occurring, growth stage, and economics. We have had southern rust show up in 10 of the last 11 years I’ve been serving in this area. If you spray a fungicide at tassel, you may not have enough residual to ward off southern rust when it appears later, potentially resulting in the need for a second application. In our area thus far, I’m not seeing enough disease pressure in many fields to warrant a fungicide at tassel; consider delaying an application till later for economic and resistance-management reasons. Ultimately this decision needs to be done on a field by field basis. Please also see this UNL CropWatch article regarding fungicide application and corn growth stage. Although I don’t have a photo of it, I’ve also seen common rust in the mid and lower portions of corn canopies thus far.
Determining Your Needs
In the Clay County Fair Open Class flyer printed in the Clay County News, you will find the middle page pulls out and is a survey. Nebraska Extension in Clay County and our Clay County Extension Board have launched a survey to determine programming/information needs you deem critical to you and your families. We know that we provide crop, 4-H, and some horticulture programming and information, but there is much more that Nebraska Extension as a whole provides that we haven’t necessarily offered as much as we could in Clay County.
The survey is meant for those of you in Clay County, if you’d be willing to take less than 5 minutes to fill it out, we’d greatly appreciate it! You can also fill it out online at: https://www.surveymonkey.com/r/clayext. The survey will remain open till the conclusion of the Clay County Fair on July 12 this year. Please pass this information along to Clay County constituents as we’re trying to reach as many people as possible. It really is important that we receive as much feedback as possible. It’s important as the goal is to better serve you-and we can’t do that without your input! Please do take a few minutes and complete this for us as we’ve only had a handful complete it thus far. Thank you and please encourage others to complete it as well!
Corn is approaching or at V7-V8 growth stage. A few weeks ago, we published research results in our UNL CropWatch website. That information can be found in the links below the video. If you are interested in trying this in your field this year, please see the Nebraska On-Farm Research protocals also shown below.
July 1 is the upcoming Weed Science Field Day at UNL’s South Central Agricultural Laboratory near Clay Center. The brochure with more information is shown below as photos; please click on the photos to enlarge if they are difficult to read. You may RSVP to Dr. Amit Jhala at (402) 472-1534. Hope to see you there!
This year I was counting my blessings as we made it through May with no tornadoes in Clay County and no Memorial Day storms! Yet history seems to repeat itself on days. Last year, hail went through the counties north of us on June 3. This year, hail hit us on June 3rd….an estimated 30% of Clay County. Please also see the resources listed at the end of this post for more specific information regarding decision-making.
For more information on hail and replant decisions, please see:
Many of us have been there…we’ve been asked a question in which the answer can be deemed controversial because the topic is based on emotion and beliefs. How do we respond? Do we get caught up in the emotion and passion of the issue and try to force our beliefs on others? Do we shy away or try to avoid an answer altogether by remaining silent?
Last week’s Sensitive Issues Media and Communications Training was developed to help all of us through these situations. It was a remarkable experience working with an amazing group of ladies, all passionate about food, but looking at food from a variety of perspectives and taking an issues-based approach in developing our team. Our team was comprised of a livestock expert, a manure expert, two food and nutrition experts, a communication’s expert, and myself from a crop production perspective. Special thanks to Dr. Chuck Hibberd, Nebraska Extension Dean and Director, for providing us a New Audiences Innovation Grant to partially fund this training. You can catch the conversation on Twitter at #SIMCT15.
We invited the Center for Food Integrity to conduct their Engage training with us, which was sponsored by the United Soybean Board. This training uses “the power of shared values to highlight industry trends and teaches strategies for using values-based messaging in daily conversations, and public speaking and media opportunities.” There was discussion, role playing, and mock media interviews. The training challenged me to use something I also just learned from “7 Habits of Highly Effective People” training….Seek first to Understand, then to be Understood.
Essentially, ask questions. Understand why a consumer believes X, Y, or Z about food and agriculture. Universal values include:
Seek to understand the other person’s values by listening and asking questions. Then share by communicating about common values telling your food and ag story. We can’t really script this. We can’t be so vague that we’re not credible. For example, the following is vague and perhaps over-used:
By doing X we help the environment.
Instead, we need to be willing to talk about the hard issues with authentic transparency…to share our own individual stories.
I also desire water that is safe for my family to drink and desire for there to be enough water for future generations. That’s why my colleagues and I work with farmers to use research-based irrigation scheduling tools. Doing so helps reduce over-irrigation which can reduce the nitrate levels reaching our groundwater and the amount of water being pumped from the aquifer.
There were a few surprises for me. The first being the progress in one year (based on the Center for Food Integrity’s research) that we’ve made in consumer trust. This slide is essentially saying that 42% of consumers feel the food system is going the right direction (up from 34% last year). Men are more trusting of the food system at 48% believing the food system is on the right track. 32% of women feel the food system is on the wrong track.
Another surprising, yet encouraging piece of information for me to see is which people are trusted the most on sensitive topics. On the topic of genetically modified foods, University Scientists topped the list, a Scientist that was a Mom was second, and Farmers were third. This is different than other research I’d seen, so I was excited about this. It was a survey of 2005 individuals conducted in 2014 and was encouraging from the standpoint that we do still have an opportunity to share our stories with those who truly desire to know more about where their food comes from. We will never change the activists, but we can reach the middle.
Finally, I loved the following quote which is so true:
A picture is worth 1000 words; a video is a library.
They showed the following video from Similac entitled, “The Mother ‘Hood“. Instantly, my mind went to how easy it would be for ag to do something similar. We tend to be so divided, but division is killing us. We are in the business of providing a safe, affordable, food supply to the world…but beyond that, our diversity provides consumer choice. If you watch the video, consider what is the common issue that could bring all of ag together. I have some ideas and my team members and I have discussed what a similar video with diverse agriculture groups would look like. What are your thoughts and ideas?
