  • Bridging Conservation and Profitability on the Prairie: What Every Rancher Should Know
    In this episode, we sit down with Dawn Butzer to discuss her journey from her early life and career to her current work and future aspirations. Dawn shares insights into her deep connection with conservation and land management, emphasizing partnerships with the NRCS, South Dakota Grassland Coalition, and Ducks Unlimited.Early Life and CareerDawn Butzer’s roots in agriculture and conservation run deep. Growing up, she developed a strong appreciation for the land, learning firsthand about the challenges and opportunities in sustainable agriculture. Her early career saw her working in various capacities, where she gained valuable experience in land management, conservation programs, and working with producers to improve soil and water health.Current WorkDawn is currently involved in conservation efforts that focus on grassland restoration, soil health improvement, and sustainable grazing practices. Through her work with the NRCS, she collaborates with ranchers and landowners to implement conservation plans tailored to their needs. She is also actively engaged with the South Dakota Grassland Coalition, which promotes voluntary conservation efforts among producers. Additionally, her work with Ducks Unlimited aligns with large-scale restoration efforts, ensuring that grasslands remain viable for wildlife and agriculture.Future AspirationsDawn is passionate about continuing to bridge the gap between conservation initiatives and agricultural operations. She aims to expand her outreach, working closely with producers to adopt practices that benefit both the land and their bottom line. With increasing challenges such as climate variability and land-use changes, she hopes to play a crucial role in advocating for policies and programs that support long-term sustainability.Key Partnerships and ProgramsNRCS (Natural Resources Conservation Service): Dawn works with the NRCS to provide technical and financial support for landowners looking to implement conservation practices. These efforts include rotational grazing systems, soil health initiatives, and grassland preservation.South Dakota Grassland Coalition (SDGC): This producer-led organization promotes grassland management techniques that balance productivity with ecological health. Dawn collaborates with SDGC to support ranchers in adopting regenerative grazing methods.Ducks Unlimited: Recognizing the vital role grasslands play in water conservation and wildlife habitat, Dawn works alongside Ducks Unlimited on projects that protect these ecosystems while ensuring economic viability for ranchers.Resources Mentioned in This EpisodeDawn and the hosts discussed several books and articles that provide further insight into conservation and sustainable agriculture. Here are a few key recommendations:Native Grass Forages by Patrick Keyser – Native Grass Forages for the Eastern U.S." by Patrick Keyser is a comprehensive guide focusing on the establishment, management, and benefits of native warm-season grasses as forage in the eastern United States. Designed for farmers, technical advisors, scientists, and conservationists, the book offers practical, science-based information on this topic.  See: https://nativegrasses.tennessee.edu/native-grass-forages/Scripture, Culture, and Agriculture by Ellen F.

  • New Research Reveals Why Fertilizer Efficiency Depends on More Than Nitrogen Rates and Soil Chemistry
    In Part 2 of our series with Dr. Bhupinder Farmaha, we go deeper—literally. Dr. Farmaha joins us again to talk about what’s happening below the topsoil and why it matters more than ever in nutrient decision-making. From soil testing at deeper depths to assessing the biological activity of soil microbes, Bhupinder's research is showing that one-size-fits-all recommendations just don’t cut it anymore.He shares a bold finding: only 50% of cotton production sites in his trials respond to nitrogen application. That insight could shake up fertilizer recommendations in a big way. Bhupinder also dives into chicken litter studies, the promise and risks of micronutrient buildup, and the long-term effects of organic amendments on sandy South Carolina soils.Highlights include:Working with USDA partners to integrate biological indicators into soil testsChicken litter vs. synthetic fertilizer: trade-offs and recommendationsHow climate-smart practices can stabilize yields in unpredictable weatherRethinking seed selection in light of resilient management systemsThe episode ends with a look at where this work is headed—toward more holistic, systems-based nutrient management. Bhupinder makes a strong case for moving beyond chemistry alone and embracing biology and farmer experience as critical parts of the fertility equation.Resources Mentioned in This EpisodeCotton, Country Conservation: An 8-Year Case Study in Regenerative Agriculture (Following SC Farmer Sonny Price's path of reducing input costs, increasing organic matter, and saving over $2.5 million):  soilhealthlabs.com/projects/cotton-country-conservation

  • How to Cut Fertilizer Inputs Without Sacrificing Yield: Soil Fertility Specialist Shares New Soil Health Data
    In Part 1 of our two-part conversation with Dr. Bhupinder Farmaha, we dig into the reality of shifting farmer mindsets around nutrient management. As Clemson Extension’s Soil Fertility Specialist, Bhupinder walks us through his journey from studying soil science at the University of Illinois to on-farm research in Minnesota and across South Carolina—where he’s working side-by-side with farmers to reevaluate how much (and what kind of) fertilizer is really necessary.We explore the difficulty of challenging generational practices and the importance of building trust through local, participatory research. Bhupinder shares stories of farmers like Sonny Price, who haven’t applied potash for nearly a decade—without any loss in yield—and how that’s pushing the envelope on conventional wisdom.Topics covered include:Why scaling back fertilizer use is as much cultural as it is agronomicThe importance of working on real farms, not just research stationsBuilding peer-to-peer farmer networks for changeHow soil health practices like cover crops impact profitability, pH, and nutrient cyclingLearning from farmer-led experiments and shifting extension modelsThis episode lays the groundwork for a broader conversation about nutrient efficiency, soil health, and what it takes to bring about real-world change in agricultural systems. Whether you're conventional, curious, or fully regenerative, there’s something here for everyone interested in growing smarter.Resources Mentioned in This EpisodeCotton, Country Conservation: An 8-Year Case Study in Regenerative Agriculture (Following SC Farmer Sonny Price's path of reducing input costs, increasing organic matter, and saving over $2.5 million): soilhealthlabs.com/projects/cotton-country-conservation

  • Seasoned Rancher Shares Simple Livestock Strategies For Healing the Land and Boosting Ranch Profitability
    🧲 Quotable Quotes“You can’t graze a landscape unless you understand what that landscape wants to be.” — Dave Ollila“We’ve got a chance to tell a story—to show that red meat can come from stewardship, not just consumption.” — Dave Ollila“The biology in the rumen is the same biology in the soil. That’s no accident. That’s design.” — Dave Ollila👩‍🌾 About our GuestDave Ollila is a seasoned rancher and agricultural educator in Butte County, South Dakota. With a career spanning over 25 years, he has made significant contributions to sustainable livestock management, particularly in multi-species grazing and soil health.​Dave’s great-grandfather immigrated from Finland and homesteaded in Butte County in 1916. Dave and his wife, Holly, continue this legacy by raising sheep and cattle on the same land, emphasizing practices that align with the region's semi-arid conditions (South Dakota Magazine.)​Professionally, Ollila served as the South Dakota State University (SDSU) Extension Sheep Field Specialist until his retirement in February 2020. He then joined the South Dakota Soil Health Coalition (SDSHC) as a Soil Health Technician, focusing on assisting producers in western South Dakota with soil health consultations (South Dakota Soil Health Coalition).🌾 In this EpisodeIn this deeply engaging conversation, Dave Ollila shares hard-won wisdom from decades of grazing and ranching in western South Dakota. We dive into the ecology of the prairie, how sheep and cattle mimic native herbivores, and how integrating multiple species—and technologies—can regenerate landscapes, boost ranch income, and reconnect producers to the land’s natural rhythms.🐑 Topics CoveredWhy context matters in livestock integrationEastern SD = tallgrass prairie; Western SD = shortgrass prairieMatching livestock species (e.g., sheep vs. cattle) to land, rainfall, and forage typeMulti-species grazing as ecological mimicryCattle as analogs to bison: bulk grazers of coarse grassSheep and goats as browsers akin to deer and elkBetter soil biology and insect/bird diversity through livestock diversityVirtual fencing in practiceUsing “No Fence” GPS collars to control small ruminantsHow virtual fences help manage weed outbreaks and reduce fencing costsCurrent limitations: signal strength, battery life, and trainingTraining livestock to graze invasive speciesHow sheep learn to consume Dalmatian toadflax through experienceLessons from Dave's cooperative research with BLM and insights from the Targeted Grazing ManualBenefits of sheep in dry countrySheep’s ability to thrive on snow as a water sourceTheir lower infrastructure needs and suitability for women and youthIncome diversity through meat and wool (up to 200% lambing rates)Why we need to educate our "city cousins"Comparing prairie biodiversity to the AmazonUrban lawns, golf courses, and parks can also sequester carbon“We’re not enemies—we’re partners with nature.”📚 Resources Mentioned1.

  • How to Boost Animal Health and Farm Productivity with Ecological Principles
    Guest: Dr. Gustavo Lascano, Associate Professor of Ruminant Nutrition, Clemson UniversityHost: Drs. Gabe Kenne & Buz KlootLength: ~70 minutesIn this conversation with Dr. Gustavo Lascano, Ruminant Nutrition Specialist at Clemson University, we discuss integrating ecological principles like succession and diversity into farm management to improve animal, soil, and human health. Dr. Lascano describes intricate details of ruminant nutrition and reinforces that it should focus not only on calories but also on proper nutrient balance and feeding the microbial ecosystem within the rumen. His expertise in this field comes not only from advanced degrees and field and laboratory research, but also from experiencing indigenous agricultural systems firsthand and seeing how they offer valuable insights into sustainable, low-input food production systems.Episode Highlights:Rethinking Production Systems with Ecological SuccessionDiverse Background with Global RootsFree Choice Feeding & Ruminant EfficiencyRumen Microbiology & Soil ParallelsIndustrial vs. Regenerative Feeding ModelsAgroecological Inspirations from the AmazonThe Role of Animals in Regenerative AgTo learn more about Dr. Lascano and ruminant nutrition, check out the below links:Gustavo Lascano at Clemson UniversityFaculty ProfileSoil Health Lab Podcast ArchivesVisit WebsiteFeatured in the episode: Cotton, Country, Conservation (8-year regenerative agriculture study)

About Soil Health Labs

The Soil Health Labs are located in the Environmental Health Sciences Department in the School of Public Health at the University of South Carolina. That may be surprising to most, especially since the University of South Carolina has no Ag School! Our mission is to promote soil health, not only as something that’s good for the farmer and the environment, but we also want to highlight soil health as a public health tool. Think about it. Healthy soils and healthy crops, mean healthy farmers and consumers, never mind an ever-improving environment. One idea we are embracing is that of Regenerative Farming where we embrace the idea that if farmers change the way they manage the soils, they can actually improve, or regenerate environmental conditions through less disturbance, keeping soils covered with residue or canopies, keeping live roots I the soil year round and be reintroducing animals into the whole system. While we cut our teeth promoting soil health through video and social media (Soil Stories; Under Cover farmers: Science of Soil Health; Merit or Myth; Growing Resilience) we do have several research and outreach projects that we are doing with farmers in South Carolina.
