  • Reaching Producers Beyond the Extension Meeting

    Reaching Producers Beyond the Extension Meeting
    2026/08/18
    Visit RedDirtAgronomy.com Daniel Adamson Ph.D., Oklahoma State University Extension soil and water conservation specialist, joins Dave Deken, Brian Arnall Ph.D. and Josh Lofton Ph.D. for a conversation about building an Extension program in a changing communications landscape. They discuss YouTube, short-form video, social media, field demonstrations and why seemingly ordinary work can become valuable educational content when producers get to see something they normally would not. Adamson currently serves as an OSU assistant professor and Extension specialist focused on soil and water management and conservation. The conversation also gets practical: what equipment actually matters for producing useful videos, why digital outreach can be difficult to measure inside traditional academic systems, and how artificial intelligence raises the stakes for putting reliable, unbiased agricultural information online. From a phone and microphone to a soil pit and a good explanation, the group makes the case that reaching producers is increasingly about meeting them where they already search. Key takeaways: YouTube and short-form video can reach producers who may never attend a traditional Extension meeting.What feels routine to a specialist may be completely new—and highly useful—to someone watching from the farm.Good agricultural video does not require a truckload of equipment; steady footage and clean audio can make a major difference.Digital outreach can produce measurable reach even though traditional academic evaluation systems may still place more value on peer-reviewed publications and fact sheets.As AI becomes another source of agricultural answers, recognizable, research-based Extension content becomes increasingly important. Detailed Timestamped Rundown 00:00–02:57 — Why Extension communication matters now Dave introduces the episode around Extension, communication and getting good research-based information to producers who increasingly search for answers on their phones. He previews YouTube, video production and the growing importance of trusted information in an AI-driven world.02:58–05:31 — Meet Daniel Adamson The group reintroduces Adamson nearly two years into his OSU career, with some Oklahoma-versus-Texas banter and a little background on his rural roots.05:32–07:15 — Building an Extension program Adamson talks about finding the right "lanes" for his program and learning what will actually meet people's needs. One unexpected responsibility has been onsite wastewater treatment—better known to most rural homeowners as septic systems.07:16–09:20 — The communication problem The conversation turns to one of Adamson's biggest questions: how Extension reaches people in the ways they actually consume information while respecting their time. Video and social media become central to that discussion.09:21–13:48 — From radio and websites to YouTube Arnall remembers an Extension landscape dominated by websites, radio and television. Dave contrasts that with Oklahoma Wheat Commission videos, describing a YouTube channel that grew rapidly as producers found timely crop information there.13:49–18:50 — Short videos and ordinary Tuesdays Lofton and Adamson discuss the surprising reach of short-form videos. Adamson's simple soil-structure clip earns thousands of views, reinforcing the idea that work scientists consider ordinary can be genuinely interesting to producers.18:51–23:30 — Local audiences become regional audiences The group compares Facebook, X, Instagram and YouTube audiences and discusses how online field days and videos can reach people well beyond Oklahoma. The practical advice: capture footage while the work is happening, even if narration comes later.23:31–27:07 — Does academia reward digital outreach? Arnall and Lofton describe a mismatch between the ways audiences increasingly consume Extension information and the ways universities traditionally measure scholarly productivity. Fact sheets and peer-reviewed publications count differently than podcasts, blogs or social videos.27:08–30:29 — Communication creates opportunities The group discusses how online visibility can build reputation, generate speaking opportunities and help specialists become recognizable resources. Arnall describes finding a place in academia through communication and "edutainment."30:30–33:51 — Adamson's North Star: help people Adamson explains that he wants to learn useful things, teach them simply and avoid overlooking basic information just because a specialist has seen it many times. Research quality remains essential, but valuable Extension knowledge does not always fit neatly into an academic mold.33:52–35:36 — Why YouTube stands out In-person education remains valuable, but Adamson is particularly interested in concise, useful videos. He illustrates the point with his own experience searching YouTube for practical help dealing with a mole in his garden.35:37–39:16 — ...

  • Farm Recovery: Neighbors Clear the Way After The Storm

    Farm Recovery: Neighbors Clear the Way After The Storm
    2026/08/04
    A tornado can leave a farm standing and still prevent the next crop from going into the ground. North-central Oklahoma farmer Karen Eifert Jones shares what happened after the April 23 tornado passed over her family’s headquarters near Enid and tracked across five of their farms. Barbed wire, lumber, shingles and household belongings covered fields and pastures that needed to be planted within days. Karen explains how more than 150 volunteers, neighbors and emergency crews helped locate equipment, wind-damaged fence and walk fields shoulder to shoulder before the next rain. She also shares practical lessons about disaster donations, community shelters, farm mental health, USDA fence assistance, crop decisions and the local relationships that make agricultural recovery possible. Key takeaways: Tornado debris can create serious hazards for planters, combines, livestock and vehicle tires long after the storm.Local emergency coordinators can help farmers locate highly specialized equipment such as hydraulic wire winders.Flexible cash donations allow trusted local groups to purchase the tools and supplies survivors actually need.Community recovery must address mental health, livestock losses, warning communication, and access to safe shelter.Long-term crop rotations still require flexible decisions based on moisture, weeds, labor, cattle, and planting windows. Detailed timestamped rundown 00:00–02:47 — Episode introduction Dave introduces Karen Eifert Jones and the episode’s central story: recovering farmland after a tornado scattered fences, construction material and household debris across multiple farms.02:47–03:55 — What is growing on the farm Karen reviews millet planting, completed canola harvest, nearly completed wheat harvest, full-season corn, soybeans, grain sorghum, double-crop soybeans and the cattle operation.03:55–05:04 — Making annual crop decisions The discussion turns to balancing a five-year operating plan with short-term field conditions, rainfall and individual farm constraints.05:04–06:52 — Why millet fits one difficult farm Karen explains how access limitations make hay the only practical option on one rented farm and why millet has become its most profitable use.06:52–07:11 — Hay sales build new relationships A wheat field overtaken by rye was harvested as hay, creating a relationship with a drought-stricken customer who later subleased pasture.07:11–08:49 — Canola’s place in the rotation Canola may only break even in some years, but Karen values it as a rotation tool that can improve the following wheat crop.08:49–09:33 — Wheat and canola yield losses Both crops produced roughly one-quarter of expected yields because the moisture needed during production did not arrive.09:33–10:57 — Why the farm still double-crops Double-cropping helps keep the soil covered, manage weeds and provide an opportunity for revenue rather than leaving ground idle.10:57–12:06 — Soybeans, sorghum and weed pressure Moisture, broadleaf weeds, grasses and Johnson grass influence which crop goes into each field.12:06–12:56 — Why double-crop corn does not fit The family has considered double-crop corn but regards the timing and production potential as too marginal.12:16–12:56 — Connecting crops and cattle Corn and sorghum residue can be grazed, so water access, fencing and planned cattle locations also influence crop choice.13:03–15:10 — Buying equipment versus hiring custom work Karen describes how labor availability, machinery costs, custom rates and cooperation with neighboring operations shape equipment decisions.15:10–16:34 — Preparing for generational transition Her son is working as an hourly employee before purchasing shares in the operation, while the family expands primarily through rented land.16:44–19:23 — Remembering the April storm Dave recounts watching tornadoes near Braman and Enid before realizing one was approaching Karen’s farm and Vance Air Force Base.19:23–20:28 — Karen watches from Stillwater Karen was attending an Oklahoma State University event and sheltered in the student union after discovering her friend’s hotel lacked an adequate tornado plan.20:28–21:43 — The tornado crosses the operation A neighbor sent video showing the funnel over Karen’s house. The path crossed the headquarters and continued along five farms.21:43–22:56 — Debris blocks spring planting Four fallow farms were filled with wire and wreckage just as full-season planting needed to begin.22:56–24:29 — The search for wire winders After two unsuccessful days, Karen asked the local emergency command center for help locating a hydraulic wire winder. Within minutes, one was found—and a neighbor located another.24:29–25:06 — One request produces two crews Karen’s church planned to send volunteers, while emergency coordinators arranged an additional crew.25:06–26:29 — Walking fields shoulder to shoulder Volunteers searched the ...

  • Can Quarter-Acre Trials Guide Whole Farms?

    Can Quarter-Acre Trials Guide Whole Farms?
    2026/07/30
    A new farming practice should earn a producer’s confidence before it is trusted with an entire field. Oklahoma State University Extension specialists Brian Arnall, Ph.D., and Josh Lofton, Ph.D., explain how small-plot research becomes practical agronomic guidance for Oklahoma producers. They discuss replication, field variability, statistical confidence, and the steps researchers take before recommending changes involving nitrogen, plant population, varieties, or other crop-management decisions. They also explain why on-farm cooperators and producer-run trials are critical for testing whether research results hold up under commercial conditions. Key takeaways: Small plots help researchers isolate treatment effects by reducing differences in soil, rainfall, pests and field management.A large field demonstration may look convincing, but without replication it can be difficult to separate a treatment response from normal field variability.Results should usually be repeated across multiple years, locations, soil types and weather conditions before becoming a broad recommendation.Researchers may require greater confidence when a recommendation would significantly change established practices or put a producer’s return on investment at risk.Producers can manage adoption risk by testing a new practice on a few strips or limited acres before applying it across the operation. Detailed Timestamped Rundown: 00:00–02:13 — Episode introduction and research question Dave Deken introduces the discussion of “big science on small acres” and previews how small-plot trials become real-world recommendations. Brian Arnall and Josh Lofton are introduced along with their OSU Extension roles.02:16–05:09 — Why researchers use small plots Arnall explains that an entire trial may fit within roughly a quarter acre. The smaller area allows researchers to keep treatments on similar soil and under comparable rainfall, pest pressure and environmental conditions. Small plots also make it possible to test many treatments with several replications.05:09–08:19 — Matching plot size to field variability Lofton explains that researchers must decide whether to minimize variability with smaller plots or include more variability within longer plots. Forage research may require longer plots, while detailed plant-physiology questions may be studied in one-foot-by-one-foot microplots.08:21–10:14 — Demonstrations versus replicated science Large demonstrations can show whether a practice appears workable across several acres, but they may not provide strong scientific evidence without replication. Researchers are cautious about using a producer’s land for an idea that may reduce yield or profitability.10:14–13:26 — Testing across years and environments A practice that works repeatedly near Stillwater may respond differently in western Oklahoma’s sandy soils or the wetter, heavier soils of northeastern Oklahoma. Researchers distinguish between an observation, a tentative practice to try and a formal recommendation.13:26–16:19 — Blocking, variety trials and experimental tradeoffs Lofton describes how treatments are grouped into blocks so each treatment experiences a comparable environment. Trials containing too many varieties can stretch across changing soils and conditions, so researchers may divide varieties into separate maturity groups.16:19–19:15 — Statistical error and recommendation risk The group discusses the possibility of concluding that a treatment works when it does not, or concluding that it does not work when it actually does. Arnall emphasizes the risk of recommending a product or practice that fails to produce a dependable return.19:15–22:10 — Why confidence standards can change Lofton and Arnall discuss the difference between 90% and 95% confidence. The appropriate threshold depends on the research question, the quality of the field conditions and the consequences of being wrong. Major changes to accepted practices demand stronger evidence.22:10–24:22 — Evidence behind major management changes The speakers compare agricultural risk with the much higher certainty required in medicine and engineering. Arnall says he had approximately six years of data before becoming highly vocal about delaying some nitrogen applications.24:22–26:54 — Challenging assumptions and explaining mechanisms Researchers do not rely on statistics alone. They ask whether a result makes biological and agronomic sense, discuss it with colleagues and collect additional plant or soil measurements to explain why it occurred.26:54–29:44 — Scientific disagreement strengthens recommendations Arnall and Lofton explain that members of the research team frequently disagree about mechanisms and interpretations. Those arguments continue until the data support a consistent OSU recommendation. Repeating work with different students or projects can provide additional confirmation.29:46–32:10 — Moving research into ...
