Through the years I’ve been blessed to meet many individuals including farmers/ag industry professionals who served (or continue to serve) our Country in the military. I’ve observed how service has influenced perspective on life’s difficulties for many individuals. And, I’ve observed how impacts of service have resulted in additional difficulties in life after service for some. There shouldn’t be shame regarding the struggle or in seeking help. While it can be scary, healing can come in the midst of honesty and vulnerability. Tonight I watched a special TV interview with four highly decorated individuals of the Iraq/Afghanistan wars-a couple of whom I’ve read their books. It was interesting hearing their perspectives on combat then coming home, on being in the military and then getting out, and much more. They ultimately shared how difficult it is after war and after service to step into civilian life and how important their military connections were in keeping them going. They also shared how important it was to find a sense of purpose in serving others and living life well in honor of those with whom they served who never made it home. Most likely all of us can think of a family member or friend who has served. Those individuals may have stories and/or wounds without words. Let’s be sure to show our gratitude to them for our freedom in America. Thank you to all our Veterans and all those in our Armed Forces for your service! Thank you also to their families!
Fall Applied Anhydrous Ammonia: When I began my Extension career, it was a different perspective for me to experience fall applications of nitrogen. My perspective from our farm was in-season nitrogen applications. Since then, there’s been several research based studies regarding the benefits of in-season nitrogen application. I appreciate there’s different reasons for the ways farmers approach the decisions within your farming operation. I’ve also observed more farmers of various operation sizes moving to more in-season applications. The reasons they’ve shared with me include: wanting to be more efficient with nitrogen application when the plant needs it, worried about any loss in off-season and wanting better water quality for kids/grandkids, research shows hybrids need nitrogen later in season, wanting to find a way to make it work before any potential regulation, and wondering if they can get by with less nitrogen with better timing in season. We also know today’s farmers in general have become increasingly efficient in both nitrogen and water use. There’s an interesting article in this week’s UNL CropWatch (http://cropwatch.unl.edu) where a multi-disciplinary team of authors share on nitrogen application in the fall having enhanced risk due to potential loss. This is due to data on the increase in extreme precipitation events over time that can lead to increased nitrogen loss through leaching and/or denitrification. We also know that there are years, like last winter, where areas I served didn’t even receive 2” of precip from fall through early May. So every year is different. Because we can’t predict the weather, the authors suggest, “Consider a more robust and less risky N management method that includes: applying a small percentage of N near planting time; follow with sidedress N applied as late as is possible given your equipment capabilities or several fertigation applications that are timed with crop uptake needs; and ensure the final application of N is done before the R3 growth stage.” They also suggest the following if you plan to apply N in the fall, “Avoid fall N application for soils of hydrologic Group A (sand, loamy sand, sandy loam) and Group B (loam, silt loam, silt); Avoid fall application of fertilizers containing urea or nitrate; Apply only when soil temperature is consistently below 50°F to slow nitrification (Last week temperatures fluctuated above and below 50°F at the 4-inch depth.); Use an inhibitor with known efficacy when applying N; and Hope for dry cold weather!”. The following is a really good resource if you’re interested in different University studies regarding various nitrogen inhibitors: https://www.ag.ndsu.edu/publications/crops/nitrogen-extenders-and-additives-for-field-crops. It’s too long to share here. A general summary of studies involving the inhibitor N-Serve used with anhydrous ammonia applications shows that it consistently resulted in increased ammonium nitrate the following spring (thus it worked well as a nitrification inhibitor). Yield increases were inconsistent throughout studies and years due to precipitation differences amongst the years. That resource also discusses research regarding other nitrification inhibitors in addition to urease inhibitors and slow-release N products, so it may be a helpful resource. We’ve also had farmers conduct on-farm research studies in the past looking at the application of inhibitors in anhydrous vs. none. They also haven’t consistently shown a yield increase (and we failed to always take soil samples to document any differences in ammonium nitrate the following spring). But if you’re interested in trying a study this coming year looking at nitrogen timing or use of inhibitor, please contact me or your local Extension Educator and we’d be happy to work with you!
Last week I had the opportunity to attend and speak at the Weed Science School. It was an interesting day of learning, discussion, even reflection. Dr. Amit Jhala, Weed Science Specialist, did a really nice job of organizing the day and creating opportunities to hear from University, Industry, and Nebraska Dept. of Ag (NDA) speakers in addition to providing hands-on activities. While dicamba was a topic that was discussed, we didn’t hear about EPA’s ruling till the following day that the RUP products for soybean will be re-registered. Tim Creger with NDA shared that 6 other dicamba products, most with pre-mixes, will be registered this year. He also shared there are 40 ag labeled dicamba products that are not restricted use pesticides, and as long as they aren’t registered for soybean use, he doesn’t anticipate they will become restricted use pesticides. Comparing NDA claims from 2017 to 2018, they received 95 claims (24 investigated due to lack of resources) in 2017 compared to 106 (50 investigated but only 31 resulted in full investigations due to desire of the person filing the complaint) in 2018. Of the 106 claims in 2018, 17 were non-ag related.
In last week’s column, in sharing about fall burndown apps, I had mentioned that 60% ofmarestail (horseweed) in Nebraska germinated in the fall. An updated number of 90-95% fall germination for Eastern Nebraska was shared. This once again emphasizes the importance of considering fall apps for fields with marestail pressure.
Dr. Kevin Bradley from University of Missouri shared on 7 points he’s learned from 15 years of researching waterhemp. They included: Never underestimate waterhemp (I’d say the same for palmer); Era of simple, convenient, quick control is over; Use full herbicide rates and pre-emergence herbicides with residual; Overlap pre + post applications (which we also see with palmer-put that post on a week earlier than you think you need it); Glufosinate, dicamba, and 2,4-D may work now but they’re tools being abused; New traits won’t solve the problem; and Get rid of herbicide-centric way of thinking-we need an integrated approach. He thought he was sharing something shocking in that last statement, but I’d say several of us seek an integrated system’s approach to what we do, including weed management. So ultimately, herbicides aren’t the answer for weed control and we need to be thinking about management from a system’s perspective including crop rotation, use of cover crops, residue management, seed destruction, etc. Especially as from the industry perspective presented, it takes an average of 12 years and average investment of $250 million for a new chemistry to be developed. They are seeking chemistries now that work on specific sites of action (how targets within plant) within the mode of action (specific group or chemistry number).
On November 14th, we’re hosting a Farm/Ranch Transition workshop at the 4-H building in York. This is the closest location for our area. The workshop will focus on the needs of the “sandwich generation” between parents who still own land and children who might want to join the operation, on whom farm/ranch transition and transfer often falls. The Gen2, or Sandwich Generation, will learn how to communicate with family to understand the transition and practice asking difficult questions. Legal topics will include elements of a good business entity, levels of layers for on-farm heirs control and access, and turning agreements into effective written leases. Joe Hawbaker, estate planning attorney, and Allan Vyhnalek, Nebraska Extension transition specialist, will share stories and experiences to successfully plan on the legal side. Dave Goeller, financial and transition specialist, will cover financial considerations, retirement, and compensation versus contribution. Cost is $20 per person. If more than two people are attending per operation, the cost is $15/person. Pre-register at (402) 362-5508 or firstname.lastname@example.org for meal count. Funding for this project was provided by the North Central Extension Risk Management Education Center, the USDA National Institute of Food and Agriculture Award Number 2015-49200-24226.
November 15th is the York County Corn Grower Banquet at Chances ‘R in York. Social time begins at 6:30 p.m. with a wonderful meal at 7:00 p.m. We will hear from Nate Blum, LEAD 36, on his international trip. We will also hear from local and state directors. Tickets are only $10 and can be obtained from any of the local Corn Grower directors or from the Extension Office at (402) 362-5508. The winner of the Yeti cooler from guessing plot yields will be announced, and those who guessed need to be present in order to have a chance to win. Plot results can be obtained from the Extension Office. Hope to see you there for a nice evening with a wonderful meal to hopefully celebrate the end of harvest season!
