🧲 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.

In this episode, Carl Coleman continues his deep dive into the lessons learned from years of soil health experimentation—and how they changed not only his farm but his entire career. Carl shares how the pushback he received from scientists and extension professionals led him to set up a randomized, replicated study on his farm, proving that regenerative practices could reduce inputs without sacrificing yield.We explore some of the biggest surprises from these trials, including how fields with no applied potassium actually maintained or increased soil test levels over five years—completely contradicting conventional wisdom. Carl also discusses the economic and agronomic benefits of cover crops, including how they have helped farmers reduce subsoiling, cut back on herbicide passes, and save thousands in input costs.Carl’s transition from farming to the seed business was not planned, but as demand for high-quality, affordable seed grew, he saw an opportunity to help other farmers navigate the complexities of cover cropping. Now, as the owner of Choice Ag, Carl provides tailored cover crop blends based on individual farm needs, ensuring that growers avoid common mistakes and maximize their returns.If you’re wondering how real-world farmers are making regenerative agriculture work economically, this episode is packed with practical insights and hard-earned wisdom.📌 Check the show notes for links to Carl’s seed business, research studies, and resources mentioned in this episode!Resources Mentioned in This EpisodeHow much fertilizer do we really need? https://experiment.com/projects/how-much-fertilizer-do-we-really-needNo but seriously now, how much fertilizer do we really need? https://experiment.com/projects/no-but-seriously-now-how-much-fertilizer-do-we-really-needCotton, 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

In this episode, Buz and Dickie chat with Clinton Rasmussen about the innovative use of goats for land management, particularly in combating the spread of eastern red cedar in South Dakota. Clinton shares his journey from growing up on a ranch to returning after his military service and discovering the power of goats to clear invasive brush. He discusses how these goats thrive in rough terrain and how their grazing habits can significantly reduce unwanted vegetation, including cedar trees, yucca, and other tough plants.The conversation highlights Clinton’s use of electric fencing and his experiments with no-fence collars to manage his goats across different paddocks. The effectiveness of goats in land restoration is contrasted with the challenges posed by eastern red cedar, which not only competes with grazing lands but also contributes to dangerous wildfires.Clinton explains how goats can fit into traditional cattle operations and how they offer a great opportunity for younger ranchers or anyone looking to diversify their operations. For those who may not have the capital to purchase large tracts of land or invest in a big cattle herd, goats provide a way to get started with smaller investments. Running goats alongside cattle allows you to use the same land without the need for major infrastructure or large upfront costs. It’s an ideal way for younger ranchers to gain experience and build their business over time, especially since goats can thrive in areas where cattle struggle. Clinton’s own experience shows how goats can be a stepping stone to eventually expanding into other livestock, creating a sustainable and profitable operation.One of the great advantages of goats is their relatively low water needs, especially compared to cattle. Clinton points out that once goats are established on a piece of land, they can often go quite a while without a constant water source, relying on moisture from the plants they eat, like yucca and cedar. This can significantly reduce the need for water infrastructure, as goats can be moved across the land without the need to set up multiple water points, which can be a costly part of managing cattle. This flexibility makes it easier to rotate goats through different paddocks and access areas that might be difficult to reach or impractical for cattle. For younger ranchers looking to minimize their infrastructure costs while maximizing their land use, goats offer a smart, cost-effective solution.For further reading, check out the AgUpdate article on "Tackling the Green Glacier" here and the prescribed burn resource here.

Our third and final interview with Fred Provenza unfolds like a symphony in four parts, each movement resonating with deep reflections on human connection, nature, and the inner workings of the mind. With a cadence that mirrors the unfolding of a well-composed piece, Fred takes us through a journey of shifting perspectives and shifting lives, inviting us to hear the music of the earth as it teaches us to reconnect, simplify, and grow. Like the slow movement of a piece, the interview reflects the wisdom of experience, with Fred sharing lessons learned through years of work, struggle, and discovery. Together, these four movements create a harmony of ideas that echo the timeless truths of our relationship with the world around us.Movement 1: Fred Provenza on the Role of Mindsets in Shaping Our Relationship with NatureFred explores how mindsets, shaped by polarized perspectives, can be transformed through respectful dialogue and open-mindedness. Reflecting on his experience as a teacher, he recalls how he helped students transcend the boundaries of their differing views, fostering a deeper understanding of the complex issues surrounding livestock, rangelands, and the land itself.Movement 2: Fred Provenza on Stories that Connect and Inspire ChangeFred delves into the power of stories in creating connections and inspiring transformation. He emphasizes how the act of nurturing relationships with the land can foster a sense of community, grounding individuals in something larger than themselves, while also illustrating how personal experiences—like the shared beauty of a native garden—can bring people together in mutual appreciation.Movement 3: Fred Provenza on the Purpose of His Work and Bringing JoyReflecting on his legacy, Fred speaks candidly about his life's work and its true purpose: to inspire joy and awe in others. He highlights how reconnecting with a sense of wonder, especially after facing life's challenges, can bring peace and meaning. Fred reveals his desire not for grand accomplishments, but for helping people rediscover the joy of being alive.Movement 4: Fred Provenza on the Wisdom of Letting Nature Self-OrganizeIn response to the quotes from John Kenneth Galbraith and Charles Massey, Fred offers profound insights into the wisdom of stepping back as we grow older. He discusses the gift of reduced energy levels and how this shift allows us to embrace a simpler, more hands-off approach to life—allowing nature to regenerate on its own. Reflecting on the importance of humility and learning, Fred advocates for changing mindsets and simplifying life to connect with what truly matters.As you listen to the final movement of this symphonic conversation with Fred Provenza, we encourage you to stay with us until the end. Sometimes, it’s not the facts and figures that resonate the most, but the deeper, intuitive understandings that unfold as we reflect, shift, and grow. Fred’s insights challenge us to reconsider the way we approach life, nature, and even our own existence—asking us to embrace the wisdom of simplicity, connection, and change. Stay with us to the end, because the most important lessons aren’t always found in what we know, but in how we come to understand it.

This episode of the Soil Health Labs podcast delves into the importance of peer learning among farmers, innovative approaches to soil health, and the implementation of climate-smart practices through the Climate-Smart Grown in SC Program out of Clemson and SC State Universities. Featuring insights from Dr. Lacy Barnette, this episode explores how collaboration, community support, and scientific research drive sustainable agricultural practices.From as early as middle school, Dr. Lacy Barnette was interested in sustainable agriculture. She made the very wise decision of getting her PhD in Environmental Health Sciences from us right here in the Soil Health Lab and has since moved into a position as an Extension Associate at Clemson University where she is a part of the Leafy Greens program of their Climate-Smart Grown in SC project. This Climate-Smart program is a USDA-funded initiative aimed at sustainable practices in four main crops: leafy greens, forage, peanuts, and forestry.In this interview, Dr. Barnette emphasizes the benefits of farmers observing and learning from their peers in implementing effective soil health techniques, and the importance of making scientific research relevant and actionable for farmers, particularly in South Carolina. Dr. Barnette also discusses strategies for leafy green farmers to adopt cover cropping, reduce tillage, and approaches to mulching to enhance soil health. She also touches on market influences and policy barriers that may hinder farmers from adopting perennial systems. In all, it’s important to plug oneself into a broad and supportive community, one that is involved in supporting one another's agricultural growth and, preferably, policy that supports regenerative agriculture.Dr. Barnette discusses the many varying and visible benefits of cover cropping, such as improved soil health/productivity and pest deterrent. She goes on to discuss some of the common issues some leafy green farmers may face in cover cropping. Diamondback Moths have posed a threat to some crops, for which Dr. Barnett offers some possible remedies, such as compost tea generated from plant matter of surrounding forests.Lastly, she discusses the Initial challenges and logistical hurdles in the first year of the Climate Smart SC Program, and anticipated improvements for the second year, including summer cover crops.Links and ResourcesClemson Extension Climate Smart Program: https://www.climatesmartsc.org/Rodale Institute: https://rodaleinstitute.org

In a recent interview with Dr. Gabe Kenne, Lance Samuel spoke about his family’s farm, ‘Bushels & Bags’ near Ridgeway, South Carolina. Co-founded with his wife, Kim, initially the two former personal trainers only intended to start a homestead. Their journey began with a provisional vegetable plot, which gradually expanded into a full-fledged operation centered around microgreens. Their shift towards microgreens was driven by a desire to merge their interests in health, nutrition and agriculture. They soon discovered a strong local demand for organically grown, chemical-free vegetables.Bushels & Bags is "Certified Naturally Grown" (CNG), which is similar to an organic certification, but relies on a more local, grassroots, peer-reviewed process. This method not only supports small-scale farmers but also reduces certification costs. Lance values the collaborative nature of CNG, which fosters idea exchange and mutual support among farmers.Bushels & Bags now operates on approximately 1.5 acres and emphasizes chemical-free farming. They utilize methods such as exclusion netting and no-till farming to maintain soil structure and prevent pests. Lance details their recent experiments with cover crops, comparing crimping versus mowing techniques. He found crimping—rolling cover crops flat before planting—to be superior for controlling weeds and promoting plant health, compared to mowing, which led to increased weed pressure and inhibited growth.The interview also highlights their regenerative practices, including the use of hedgerows composed of native plants and flowering species between crop plots. Lance noticed the hedgerows attracted beneficial insects and birds that help with pest control, reducing the need for chemical intervention. The hedgerows further enhanced biodiversity and managed water runoff by absorbing excess water and preventing soil erosion. In the future, Lance is interested in incorporating rainwater catchment systems to further improve water management and reduce reliance on well water.Initially the farm implemented large amounts of outsourced compost, but in recent years Lance has begun cultivating in-house compost comprised of vegetable scraps, dead leaves and spent grain from local breweries. An experiment to remove wood chips from pathways resulted in increased erosion and water runoff, and Lance has since reverted back to using wood chips on walking paths and refined the application method, which has improved water management and reduced labor.The family plays a crucial role in the farm’s operations, as the four Samuel children all contribute to the work necessary to support the farm. Operating in a remote and rural area, however, has its challenges. The farm's location, combined with the prevalence of personal gardens among locals, complicates direct sales. Despite these difficulties, Bushels & Bags has found success through regular attendance at a local farmer’s market, a CSA program, and relationships with local restaurants.Looking ahead, Lance aims to further integrate both annual and perennial crops on the farm. To beginning farmers, Lance emphasizes the value of public resources– books, videos and online courses– and heeds new farmers to first find and shadow existing operations that share their agricultural value systems.

In this conversation with Soil Scientist Buz Kloot, Dwayne Beck— former research manager to Dakota Lakes Research Farm— discusses the destructive effects of some traditional land management techniques, one of which being tillage. Tillage consistently disrupts soil pore structure and leads to the loss of organic matter, initiating a downward spiral towards desertification. He references the Sahara Desert as an example, which was once a grassland but turned into a desert due to the loss of nutrients.Beck highlights the importance of integrated farming practices that consider the land’s natural vegetation and climate. On his travels, particularly in Australia, he noticed significant differences in ecosystems based on rainfall patterns and soil water retention. He notes the challenge of farming in regions like Western and Eastern Australia, where the climate and soil conditions differ from grassland regions. He notes that in tree-dominated regions, water moves deep into the soil during winter, beyond the reach of grass-type crops. This creates a challenge under standard agricultural approaches; nutrients being in the soil, but too deep for crops to reach.He shares his insights on potential solutions, such as integrating perennial crops like sorghum in summer to utilize the nutrient cycles effectively. Dwayne mentions Colin Seis, who developed a system called "pasture cropping" or "grain and graze," which integrates tall grass species and winter crops to create a mixed-species system that enhances nutrient cycling and works in tandem with the seasons. He highlights the benefits of having a mix of perennials and annuals, as it more closely resembles natural ecosystems—urging farmers to not grow dependent on perennial grains. While annual crops focus on producing seeds, perennials primarily aim to survive until the next year— noting that Seis’ ‘grain and graze’ approach, while an insightful guidepost, will not work in every climate.Dwayne addresses the historical importance of megaherbivores in maintaining landscapes, and how the absence of these animals affects current ecosystems. The subsequent deficiency of deep-rooted species contributes to what he calls a leaky system: soil pH deficiencies leading to water and nutrient leakage. He references Randy Anderson's concept of a "death spiral," and emphasizes the need to restore the soil community to as close to its native condition as possible. This involves reintroducing diversity to rebuild soil’s capacity and productivity.In a follow-up conversation with Kloot, Beck discusses ongoing challenges and potential solutions for farming in the Jim River region, specifically focusing on salinity issues. Dwayne emphasizes the importance of integrating perennials into farming systems to address these issues, noting that perennials could help manage salinity, although every property will have its own unique needs.Beck highlights the benefits of having a mix of perennials and annuals, as it more closely resembles natural ecosystems. He notes how pH problems often stem from nutrient cycling deficiencies rather than input deficiencies, recounting an instance where he was asked in a conference how far a farmer would need to go to get lime. Beck’s answer was “Three feet.” He wants to remind farmers that lime is often in the soil, possibly beyond the reach of their standard crops, rather than miles away in a lime mine.Beck expressed his concern about the increasing emphasis on bio-oil crops like canola, flax, and soybeans, warning that an over-reliance on these crops could exacerbate issues in the Corn Belt. He also mentions innovative uses for crop residues, such as making lumber from corn stalks, and suggests that tallgrass plants could be harvested biennially for biomass production while still benefiting the soil. He acknowledges that while this approach is not as beneficial as grazing, it is still better than many standard agricultural practices.In all, Beck’s wealth of understanding on crop management and long-term planning underscores the need for strategic thinking in sustainable farming, and makes for an insightful conversation about regenerative land management.Additional Links:Dr Randy Anderson’s Spiral of Soil Regeneration:Part 1: https://www.growingresiliencesd.com/videos?wix-vod-video-id=6mckHaT2Giw&wix-vod-comp-id=comp-l0v2ecy2Part 2: https://www.growingresiliencesd.com/videos?wix-vod-video-id=aoT8x0VWu_I&wix-vod-comp-id=comp-l0v2ecy2Part 3: https://www.growingresiliencesd.com/videos?wix-vod-video-id=jJwtd5UtUak&wix-vod-comp-id=comp-l0v2ecy2Pasture Cropping with Colin Seis:https://www.wool.com/on-farm-research/weather-the-drought-with-regenerative-agriculture/Dakota Lakes Research Farm:http://dakotalakes.com/
