    How Soybeans Shape Oklahoma - RDA 510

    Soybeans are a lot more than a crop in the field, and this episode proves it. Dave Deken and Brian Arnall visit with Rick and Ginger Reimer of the Oklahoma Soybean Board about how soybean checkoff dollars are being invested in research, producer outreach, education, and consumer awareness across Oklahoma. From Red Dirt Soy and production research to classroom workshops and virtual reality tools, the Reimers share how the board is helping connect agriculture to both producers and the public. The conversation also digs into soybean rotations, the crop’s spread into new parts of Oklahoma, why soybeans are so important to livestock agriculture, and how the board has even supported feral hog control because of the damage those animals cause to crops and pasture. It’s a wide-ranging look at how soybean leadership, Extension partnerships, and strategic outreach are helping strengthen agriculture from the farm gate to the classroom Top 10 Takeaways This episode reframes soybeans as much more than a crop. The Oklahoma Soybean Board is investing not only in production research, but also in education, livestock-connected outreach, and public understanding of agriculture. Teacher training is one of the board’s biggest multiplier strategies. Ginger says the board has worked with nearly 800 teachers and is reaching around 20,000 students annually through workshops and classroom-ready materials. The soybean checkoff is tightly accountable. Rick emphasizes audits, compliance reviews, and documentation because every dollar being spent belongs to soybean producers. Research is still the budget anchor. Rick estimates about 60% of retained board funds go toward research, with another 20% to 30% supporting education and outreach. Soybeans and livestock are directly linked. Rick says most domestically used soybeans go into animal agriculture, which explains why the board supports pork, poultry, and related educational programming. Soybean production geography in Oklahoma has shifted. Counties once dominant in eastern Oklahoma are no longer the only leaders; major soybean production now includes north-central Oklahoma, and the crop is pushing even farther west. Western Oklahoma soybeans bring new management questions. Brian points to irrigated production and iron deficiency issues in high-pH soils as examples of why region-specific research matters. Digital outreach is becoming a bigger part of the mission. The board is expanding through social media, recorded workshop content, YouTube, and online education platforms. Feral hog control is a serious agricultural issue. The board’s support for control efforts shows how soybean leadership is responding to broader on-farm threats, not just soybean-only problems. Agricultural literacy is long-term risk management. Ginger makes the strongest public-facing point of the episode: informed teachers become informed communities, and informed communities shape the future of agriculture. Detailed Timestamped Rundown 00:02–01:06 Dave opens Episode 510 and frames soybeans as more than a field crop, tying them to livestock feed, producer research, ag education, and statewide outreach. He previews the conversation with Rick and Ginger Reimer of the Oklahoma Soybean Board and points listeners to Red Dirt Agronomy online for more resources.01:07–01:40 Dave introduces Brian Arnall, and the hosts set up the interview, noting it was recorded January 10, 2026, at the Oklahoma Wheat Commission booth during KNID Agrifest.01:41–03:24 Brian introduces Rick and Ginger Reimer. Rick explains his long tenure with the soybean organization and walks through the shift from the Oklahoma Soybean Commission to the Oklahoma Soybean Board after the national soybean checkoff was established, including the split of funds between the state and national boards.03:25–06:22 Ginger outlines her role in marketing, consumer information, and education. She explains how her classroom work evolved into teacher workshops that equip educators with supplies, books, curriculum, and hands-on materials. Rick adds that the board tracks reach by counting how many students those teachers serve each year. Ginger says they are nearing 800 teachers and about 20,000 students annually.06:22–08:41 The group discusses workshop themes including “Pork and Beans” and “Chicka Doodle Do.” Ginger describes using VR headsets to show students swine production and explains how different workshops are tailored for preschool through older students. Brian notes the board’s outreach goes well beyond soybeans alone and reflects the full agricultural ecosystem.08:41–10:32 Rick stresses accountability for checkoff dollars, jokingly summarizing it as “document or die.” He explains the importance of receipts, audits, and compliance reviews because the board is spending producer money. He estimates roughly 60% of the state board’s retained budget goes to research, 20% to 30% to education and outreach, and admin is kept near or under 10% when possible.10:32–13:38 Dave and Brian talk about Red Dirt Soy and the Oklahoma Soybean Board’s support for digital outreach and research communication. They highlight how the board helped make room for creative, scalable outreach ideas, including online field-day style content that can reach producers across the state without requiring travel. Rick adds that soybean research also includes topics beyond yield, such as ensuring crop protection practices do not harm beneficial beetles.13:38–15:05 Rick explains why the board supports livestock-related education: livestock is soybeans’ biggest customer. He says about half of U.S. soybeans are exported, while 97% of the soybeans staying domestic are used in animal agriculture. That is why Oklahoma Soybean Board programs often connect soybeans to pork, poultry, and other livestock sectors.15:05–17:23 The conversation shifts to crop rotation and geography. Rick says soybeans help clean up wheat fields and work well in rotations. He explains that the top soybean-producing counties in Oklahoma used to be in the east, but now counties such as Garfield, Grant, Kay, and Noble are among the leaders. Brian adds that soybeans have pushed farther west, even into the Panhandle, creating new fertility and iron-deficiency management challenges in high-pH soils.17:23–20:32 Rick and Brian explain why Oklahoma can be a strong soybean state: soil, weather, rainfall, and the crop’s fit as a double-crop option behind wheat. Brian notes the historical appeal of double-crop beans as a relatively low-risk, high-reward system. The discussion also covers soybeans’ sensitivity to timely late-season rains and the use of different maturity groups to spread production risk.20:32–25:11 Brian raises another lesser-known soybean board priority: feral hog control. Rick describes years of support for thermal scopes, traps, panels, and grain carts used in control efforts through Wildlife Services. The hosts explain how destructive hogs are to soybeans, hay meadows, pastures, and farm infrastructure, making this issue much bigger than row crops alone.25:11–29:04 Dave asks what is next for the board. Ginger says a bigger social media presence is a priority, along with posting recorded teacher workshops online so educators can revisit them later. She also describes forming a teacher advisory group, experimenting with Facebook Live training, and growing the board’s YouTube content, including Rick reading Full of Beans: Henry Ford Grows a Car from a soybean field.29:04–31:28 Dave asks what producers want from the board. Rick says growers want strong production research and continued promotion of soybeans’ value. Ginger adds a broader civic point: when they teach teachers, they are also reaching future voters, and agriculture needs a more informed public as farmland disappears under development.31:28–32:11 The episode wraps with appreciation from both sides and a reminder that agriculture works best when commodity groups and institutions collaborate. Dave closes the show and thanks listeners. RedDirtAgronomy.com

  2. The New Rules Of Wheat Weed Control - RDA 509

    The New Rules Of Wheat Weed Control - RDA 509

    What actually works in wheat weed control when the old spray plan starts slipping? In this episode of Red Dirt Agronomy, Dave Deken, Brian Arnall, and Josh Lofton sit down with Liberty Galvin at AgriFest in Enid to talk through the real-world decisions that separate a clean wheat field from a frustrating one. The conversation covers pre-emergent herbicides, burndown programs, delayed planting, competitive wheat canopies, and why one weed-control strategy rarely fits every field. Liberty also breaks down why producers need to think beyond chemistry alone. From no-till residue and seedbank behavior to variety selection, tillage timing, and even the role of fire and chaff lining, this episode is packed with practical ideas for Oklahoma wheat producers facing ryegrass, brome, cheat, and other tough weed problems. It is a sharp, funny, highly useful discussion about managing weeds with better timing, better systems, and fewer assumptions. Top 10 takeaways Wheat weed control has to be system-specific now; one standard program no longer fits every field. Delayed planting can be a real weed-control tool because it lets producers target the first flush before or near planting. Variety selection and crop competition deserve more attention as weed-management tools, not just yield tools. A dense, fast-closing wheat canopy can suppress weed emergence and make herbicides work in a friendlier environment. In heavy-residue no-till systems, burndown programs may sometimes outperform soil-applied pre-emergent products because of poor soil contact. Bare ground at green-up is not always a disadvantage; it can create an opening for spring residual herbicides. Herbicide timing and rotating modes of action matter as much as product choice when resistance is in play. Weed seedbanks behave differently by species; many grasses are shorter-lived than broadleaf weeds, which can persist much longer. Occasional strategic tillage may have value in long-term resistance management, but timing, moisture, and erosion risk all matter. Fire and chaff lining are not silver bullets, but they may become useful post-harvest tools in integrated weed-management systems. Detailed Timestamped Rundown00:00–01:34 — Dave opens Episode 509 and frames the show around a question many wheat producers are asking: what do you do when the old reliable spray program is not getting the job done anymore?01:34–03:03 — The crew records live from AgriFest in Enid, with a quick round of banter before introducing Liberty Galvin and setting up the conversation around current wheat weed-control challenges.03:03–05:06 — Liberty gives an update on building her program at OSU and describes her “spaghetti plate method” of trying multiple ideas until a clearer research direction starts to form.05:06–06:06 — She explains a pre-emergent herbicide study funded by the Wheat Commission, including trials at Lahoma, Perkins, and Chickasha, and how dramatically different those environments behaved.06:06–07:15 — Liberty shifts to a cultural weed-control and IPM study, comparing multiple systems, including variety selection, to see which wheat types compete best against weeds.07:15–09:28 — The discussion turns to delayed planting. Liberty explains how cooler temperatures and moisture patterns affect winter weed emergence, and why delaying planting can help knock out the first flush.09:28–11:02 — Josh and Brian push on the tradeoffs: smaller, later wheat may conserve resources for spring, but more open soil can also invite weed emergence.11:02–15:13 — The group digs into species-specific weed behavior, especially Italian ryegrass, and talks through spring residual opportunities, bare ground at green-up, and mixing herbicide timings and modes of action.15:13–17:34 — Economics enter the picture. Liberty points out how hard it is to recommend multiple passes in a $4 wheat market, while Brian argues that badly infested fields can still justify stronger programs.17:34–20:21 — They compare delayed planting, tillage, roundup burndown, and no-till systems, with Liberty sharing observations that residue-heavy no-till fields may not always favor soil-applied pre products.20:21–24:23 — The conversation moves into tillage in long-term no-till, including when precision tillage might help, how moisture affects the operation, and how occasional soil inversion could influence resistant weed problems.24:23–28:01 — Dave asks how long weed seeds persist. Liberty gives a great primer on seedbanks, explaining why many grasses tend to have shorter dormancy while some broadleaf seeds can remain viable for years or even decades.28:01–31:44 — Josh shares a story about deep flipping fields and unexpectedly bringing crabgrass back. That leads into a broader point from Liberty: selection pressure drives weed problems, so no single tactic can carry the whole load.31:44–35:14 — Josh asks Liberty to explain her identity as a weed ecologist rather than a purely herbicide-focused weed scientist. She lays out why understanding weed biology helps producers exploit weak points with smarter management.35:14–39:11 — The crew tackles the myth that healthy soil alone eliminates weeds, then pivots into fire as a weed-management tool, including controlled burns, chaff lining, and research showing seed destruction under the right conditions.39:11–42:31 — They explore what fire can and cannot do, how residue burns sometimes create cleaner zones, and why chaff lining could eventually reduce sprayed acres by concentrating weed pressure into narrow strips.42:31–45:56 — The show closes with a plug for Winter Crop School, more Oklahoma burn-talk humor, and a final thank-you to Liberty for a practical and entertaining conversation.

    Insurance Basics That Keep You Farming - RDA 508

    Tight margins and wild market swings are back in the driver’s seat—and producers are feeling it. Recorded at the Central Oklahoma Cattle Conference in Stillwater, Episode 508 features Clay Burtrum (Farm Data Services) walking through why insurance matters even when you hope you never use it. The crew digs into Livestock Risk Protection (LRP) basics, how price protection actually works, and what producers often misunderstand when they start using these tools. On the crop side, Clay outlines the deadlines and decisions that can make or break your coverage—plus how to think about programs like PRF (Pasture, Rangeland, Forage), annual forage, and stacking options without getting lost in the fine print. Bottom line: in a $4 wheat world with 2026 input costs, staying “bankable” means planning ahead and knowing what you bought. Top 10 takeaways Insurance is about staying bankable, not just getting a payout. LRP is price protection, not mortality/disaster coverage—know what it does. Documentation matters (example: “unborn” coverage needs validation like preg-check/bred purchase records). Stocker operators often treat LRP as all-or-nothing because margin risk is concentrated. Cow-calf operations can sometimes phase coverage, spreading risk across calf crop timing. Crop insurance complexity is real—stackable options exist, but basics come first in tight years. Deadlines drive everything (in this area, March 15 is a big one; waiting too long is a common pitfall). $4 wheat changes decisions—coverage, hail policies, and whether you even harvest vs graze-out. PRF is “rainfall interval” insurance—pick when you need rain and spread risk; it won’t cover every scenario (like quality loss from too much rain). Know your cost of production—break-even won’t keep you in business; cash flow clarity is survival.   Detailed timestamped rundown 00:00–01:46 Dave tees up the episode: why insurance matters, recorded at Central Oklahoma Cattle Conference (Stillwater).01:46–02:57 Clay Burtrum intro: Farm Data Services (Stillwater), management accounting + 25+ years insurance; LRP and crop insurance, plus helping producers see bottom line year-round.03:16–04:45 Big-picture ag economy: grain-only operators squeezed; modern costs with “1970s prices”; crop insurance complexity (stackable programs) and need to keep it basic.04:45–08:43 LRP deep dive: example of insuring a 900-lb steer; why margins need protection; common misunderstandings (full load, unborn coverage requirements, validation); “don’t let it burn down” analogy; all-or-nothing for many stocker operators vs partial strategy for cow-calf.08:43–10:27 First-time client conversation: goals, where they want to be, staying bankable; traps include ignoring USDA/FSA programs and missing support.10:27–11:25 Clay as producer: he uses the products himself; emphasizes knowing cost of production and that break-even won’t keep you in business.11:26–12:50 Crop insurance pitfalls: calling too late; major dates in the area—March 15 sales closing; July 15 reporting; flow of deadlines through the season.12:50–14:18 $4 wheat vs $7 wheat decisions: changes appetite for added coverage/hail; producer mindset shifts (harvest vs graze-out).14:18–15:38 Dual-purpose wheat and insurance: need to notify agent by March 15/short-rate timing; cannot just “leave cattle out” without process; consider double-crop rules to avoid uninsured crop risk.15:38–17:14 Policy/program landscape: farm bill uncertainty and “rules”; emphasis on working with FSA and not missing deadlines/opportunities.17:14–18:51 Specialty crop/alternative ideas: limited locally; examples like hemp market issues; unusual inquiries (tulips) and regional eligibility realities.18:51–21:45 PRF pasture coverage: sales closing Dec 1; choosing rainfall intervals; premiums and changing rules; spreading risk across intervals; limits (doesn’t cover “missed cutting” quality loss).21:45–24:05 Talking to policymakers: how programs hit local bottom lines; input costs for grazing/forage; how rural communities feel downstream impacts; even equipment/emissions issues affect harvest reality.24:05–25:43 Oklahoma risk reality: rapid weather swings; questions like quarantine/screwworm, wildfire loss—what LRP does/doesn’t cover; importance of understanding what you actually bought.25:43–27:20 “Bring one program back”: Clay wants simplicity—too many stacked options; focus on basics and bottom-line impact.

    The Hidden Herd Thieves: Biting Bugs - RDA 507

    Flies, ticks, and parasites don’t just annoy cattle—they steal gain and profit. Recorded live at the Central Oklahoma Cattle Conference in Stillwater, OK, this episode features Dr. Jonathan Cammack (OSU Extension livestock entomology & parasitology) breaking down what producers should know about common pests like horn flies, how researchers test control tools, and why day-to-day management matters more than most folks think. The team also tackles two headline issues: New World screwworm and the invasive Asian longhorned tick. Dr. Cammack explains why screwworm is such a serious wound pest, how sterile insect technique works, and why animal movement can spread risk faster than the fly ever could. Then they pivot east—where Asian longhorned ticks have been detected in Oklahoma—and discuss why explosive tick populations and tick-borne disease threats are a growing concern across the region. Top 10 takeaways for producers Pests “steal” performance quietly—stress and blood-feeding divert energy away from gain. Screwworm isn’t a nuisance fly: it targets living tissue in wounds and can escalate fast. Time matters: screwworm eggs can hatch in 12–24 hours, so delayed checks can get costly. Animal movement beats fly movement—trailers move risk hundreds of miles in a day. Sterile insect technique works because females mate once; scale and logistics are the challenge during outbreaks. Asian longhorned tick can explode in numbers because it can reproduce without mating (parthenogenesis). High tick loads can cause real blood loss, and tick-vectored disease is a growing regional concern. Feedlots are a special concern due to animal density and the difficulty of visually monitoring every animal. Good management beats extremes: not “once a year,” not necessarily “daily,” but consistent eyes-on and quick response. Research behind the scenes is constant—colonies, susceptible/resistant strains, and field tests inform what works on your operation.   Detailed timestamped rundown 00:00–01:06 Dave Deken tees up Episode 507: flies, ticks, parasites; guest Dr. Jonathan Cammack; recorded at the Central Oklahoma Cattle Conference in Stillwater.01:06–02:42 “Trip around the table” intros: Brian Arnall and Josh Lofton; setting the scene at the Payne County Expo Center.02:42–06:56 Cammack’s role: OSU Extension livestock entomology/parasitology; what he covers across livestock species; why they keep fly colonies (houseflies, blowflies) for research and pesticide trials.06:56–10:51 Colony realities: genetic bottlenecks, refreshing genetics from field populations; why “susceptible” vs “resistant” strains matter for chemical testing.10:51–14:54 How trials work: planning population numbers; counting flies on cattle with visual estimates + photos; students doing image-based counts; “2000+” becomes the practical ceiling.14:54–20:01 Screwworm basics: obligate parasite of living tissue; eggs hatch fast (12–24 hours); damage can be severe; regulatory questions around response/harvest are still evolving.20:01–27:44 Control strategy: sterile insect technique; females mate once; sterile males overwhelm wild males; program history and why scaling facilities matters as the “front” widens northward.27:44–30:40 Beyond cattle: wildlife, pets, and people can be affected; reminder that wildlife movement can complicate containment; key deer example in Florida Keys (2016–2017) discussed.30:40–33:36 Other big concern: Asian longhorned tick found in northeast Oklahoma (summer 2024); parthenogenetic reproduction; potential for heavy infestations and disease-vector risk.33:36–35:27 Wrap-up: “safe from the west (for now)” tone; thanks to guest; where to find resources (reddirtagronomy.com).

    Ask Better Questions of Your Soil - RDA 506

    Episode 506 dives into soil nutrition and the real-world decisions behind soil testing with Jace Whitehead of EnviroAg Laboratories, an OSU Plant & Soil Sciences grad who built a soil testing lab from his hometown roots and now supports producers across the Southern Plains. The crew breaks down what soil test “extractions” actually measure, why Mehlich-3 and Bray phosphorus numbers can disagree (especially in low pH soils), and why saturated paste is equal parts chemistry and “perfect brownie mix.” They also sort through base saturation talk, potassium response drivers, rooting depth, and why tissue test numbers can swing with weather more than soil supply. Up front, you’ll also hear a quick crop update recorded at the Oklahoma Cattle Conference: wheat and canola are starting to respond, diamondback moths are showing up in canola, and the big message for 2026 is to protect flexibility—make informed fertility calls, watch moisture conditions, and don’t spend like it’s a “maximum yield” year if the economics don’t pencil. 10 Takeaways In 2026 economics, flexibility matters—don’t lock in every fertility decision early.Use in-rich strips and real field info to guide N rates, especially in a “cost-cutting year.”Phosphorus is the troublemaker: pH and soil chemistry can make test results look contradictory.Mehlich-3 vs Bray disagreements often come down to what chemical pools each extractant can access.If pH is low, fix that first—otherwise you can “chase P” without getting the response you expect.Saturated paste is useful for salinity/salt issues, but it’s a technique-sensitive, “art + science” test.Base saturation ratios sound appealing, but often don’t pay to chase compared to bigger constraints.Heavy clay and shallow rooting can masquerade as “cation ratio problems”—look for the real limiting factor.Potassium response may be tied to rooting zone depth/limitations more than a simple top-6-inch soil test.Tissue test numbers can swing with the environment; treat them as clues, not automatic prescriptions.Timestamped Rundown 00:00:00–00:01:35 — Welcome + episode setup Dave previews the topic: soil nutrition deep dive and an interview with Jace Whitehead, OSU Plant & Soil Sciences alum and soil-testing lab owner. 00:01:35–00:22:44 — Crop update (recorded Feb. 13, 2026) Wheat/canola starting to respond; moisture “patchy,” with rain hopes and a reminder not to overreact early. Nitrogen timing: don’t feel forced to put “all eggs in the basket” early; use information and flexibility. Push for in-rich strips and better decision-making in a “cost-cutting year.” Pre-plant planning: soil test now for summer crops; consider partial replacement strategies on P & K if economics demand it. Canola scouting note: diamondback moth reports. Market reality check: wheat may look good but price is weak; “hot crops” might be four-legged. 00:22:44–00:24:30 — Guest introduction Brian introduces Jace Whitehead and the unusual path: starting a soils lab and building sample volume through precision ag services. 00:24:30–00:29:30 — Environmental testing + saturated paste Jace explains oilfield-related soil testing and salinity work; one-to-one extracts and saturated paste use cases. Brian’s saturated paste explanation: “perfect brownie mix” consistency as the endpoint. 00:29:30–00:36:10 — Why phosphorus tests disagree (Mehlich vs Bray) Jace raises a producer-facing problem: Bray numbers low at low pH while Mehlich can run higher. Brian breaks down the chemistry: extractants differ in what forms they pull, and acidity complicates interpretation. Practical takeaway: address pH first; be cautious about overconfidence in a single number. 00:36:10–00:40:45 — Business realities + soil trends Jace talks scale (thousands of samples/year) and why “one-off” conversations are hard to fund at low per-sample pricing. Trend discussion: rotation can drive better management attention to pH and nutrients; canola helped push rotation thinking. 00:40:45–00:49:30 — Base saturation, K response, and rooting depth Base saturation & ratios: strong theory, but often weak economic payoff to chase in practice. High-magnesium soils: often a “correlation not causation” story tied to heavy clay/rooting restrictions. Big idea: we’ve over-focused on a 6-inch slice; better fertility management looks at the rooting zone and limiting layers. Tech wish list: on-the-go tools (even GPR-style concepts) to map depth/limitations. 00:49:30–00:57:15 — What it means for producers + tissue testing reality “Find trusted advisors” who can handle both plant and soil chemistry questions, and keep asking questions. Tissue tests: Brian explains how nutrient concentrations can swing with weather/conditions, making blanket recs risky. RedDirtAgronomy.com

    How Farmers Keep A Seat At The Table - RDA 505

    Recorded live from the Oklahoma Wheat Commission booth at the 2026 KNID AgriFest in Enid, the crew sits down with Jeff Hickman—farmer, longtime ag association leader, Oklahoma higher-education regent, and former Oklahoma House Speaker—for a grounded conversation on where agriculture is headed and why local involvement still matters. Jeff breaks down how ag organizations stay viable in an era of consolidation, why multiple commodity groups working together amplify agriculture’s voice, and how public policy and regulation increasingly shape day-to-day farm decisions. The discussion also hits consumer trust, social media misinformation (and how AI can muddy the waters), and why agriculture has to keep educating an audience that forgets fast. They close with what Jeff sees coming next—trade uncertainty, the need for a dependable farm policy, and the importance of building relationships with candidates before they’re elected. Practical, candid, and very Oklahoma. Ten Takeaways Ag organizations are stronger together—shared support can keep smaller groups viable and influential.Regulation is often the real battlefield, sometimes more than legislation.Fewer rural/ag lawmakers means ag has to work harder to be understood in policy rooms.Producer involvement doesn’t have to be huge—membership alone helps fund representation and benefits.Markets can disappear even after great yields, driving tough planting decisions (sorghum example).Wheat is in a strategy moment: “What’s our thing?” like corn has ethanol—new uses/value streams matter.Consumer curiosity is a double-edged sword—interest is good, misinformation is rampant.AI can accelerate fake “credible” ag narratives, raising the stakes for trusted education.Rural issues resonate when you connect the dots (health care access, metro revenue, statewide economy).Election years are relationship years—don’t wait until after someone wins to introduce agriculture.Detailed Timestamped Rundown 00:00–01:44 — Episode open, setting: Oklahoma Wheat Commission booth at KNID AgriFest (Enid); introductions. 01:45–03:35 — Jeff Hickman joins; “many hats” across OK ag organizations and higher ed. 03:36–04:44 — Why shared management/back-office support keeps smaller ag groups viable and strengthens ag’s voice. 04:45–06:53 — Policy reality: more dependence on public policy + regulations; increased focus on agencies/administration. 07:03–08:52 — Jeff’s background: journalism/OU roles, media work, farm roots; “planting and harvest were my vacations.” 09:12–12:44 — Political pendulum swings; how DC trends show up in statehouses; fewer rural/ag-connected legislators. 12:45–15:54 — Consumer interest: good and hard; difficulty finding truth; misinformation and AI concerns; supply chain lessons. 15:55–18:29 — Global factors hitting ag (tariffs, shipping routes, even piracy) through a real-world retail/cotton example. 18:30–20:55 — Benefits/challenges of representing many groups; why having a strong government affairs team matters. 21:14–23:59 — What growers are facing: crop choice risk, markets disappearing, wheat’s future “what’s our thing?”; value of membership (and CFAP example). 24:00–27:33 — How to get more producers involved in leadership/politics; timing, family/team approach, candidate mentorship. 28:13–32:50 — Translating rural needs for urban lawmakers (rural hospitals example); rural dollars fueling metro projects.33:26–36:31 — Next 6–9 months: trade unresolved, farm bill/farm policy stability, election-year urgency—build relationships now. 36:32–38:11 — Wrap-up, thanks, and where to find resources.
