    S5 - E24: Health and Nutrition Start with the Soil with Dr. Robin "Buz" Kloot, Part II
    Nov 25 2025
    Health and nutrition start with caring for the soil. Food can and should be our medicine. Dr. Robin "Buz" Kloot of the University of South Carolina's Arnold School of Public Health and Soil Health Labs shares his perspective on connections with soil health and public health with Eric, Mary, and Jeff in this episode.

    Buz reflects on his own research but also points out what he has heard from farmers and ranchers he has worked with through the years. Building on the idea that eating is an agricultural act and food can be medicine, Buz would like health professionals, agronomists, soil scientists, farmers, and ranchers to collaborate more on soil and public health research and education.

    In addition to your own research and study of soil and human health, Buz recommends reading Fred Provenza's book Nourishment: What Animals Can Teach Us about Rediscovering Our Nutritional Wisdom.

    As always, we encourage you to cooperate with other farmers, graziers, and gardeners for peer-to-peer learning and to follow the four core soil health principles:

    1) Keep the soil covered -- Cover crops are our friends and allies; avoid bare fallows;
    2) Minimize soil disturbance -- Practice no-till or gentle tillage as much as possible in your field or garden;
    3) Maximize living roots year-round -- to improve biodiversity, soil structure, and life in the soil; and
    4) Energize with diversity -- through crop rotation, high-quality food for soil and plants, farm enterprises, and livestock integration.

    The 4 The Soil team recently commissioned a new set of art posters to help people remember the four principles of soil health and celebrate that “We Are 4 the Soil!”. If you are personally or professionally interested in printing and framing the soil health artwork, the 16” by 20” posters are available for purchase and printing as single posters or a set of five posters.

    If you have questions about soil and water conservation practices, natural resource concerns, and soil health principles and practices to restore the life in your soil, call or visit a USDA Service Center, a Virginia Soil and Water Conservation District office, or your local Virginia Cooperative Extension office.

  • S5 - E23: A Fundamental Overhaul and Paradigm Shift in Soil Science with Dr. Robin "Buz" Kloot, Part I

    S5 - E23: A Fundamental Overhaul and Paradigm Shift in Soil Science with Dr. Robin "Buz" Kloot, Part I
    Nov 11 2025
    Changing course is never easy, especially if the change requires a complete overhaul at the most basic, fundamental level. Dr. Robin "Buz" Kloot of the University of South Carolina's Arnold School of Public Health and Soil Health Labs talks with Eric, Mary, and Jeff about this paradigm shift among farmers and within the soil science community.

    Buz explains how the shift in thinking and paradigms occurred. In many cases, people were focused more on the symptoms rather than the cause, for instance, soil loss through erosion or poor water infiltration. Understanding the underlying cause required a whole-system approach. For Buz, an open mind to farmers' stories and experiences, and a beginner's mindset as a scientist were required to truly grasp the dynamic nature of soil.

    If you are beginning your journey with soil health and cover cropping systems, the featured length Under Cover Farms video, Buz and his team produced, provides a good introduction and uplifts the initial experiences of farmers in South and North Carolina.

    As always, we encourage you to cooperate with other farmers, graziers, and gardeners for peer-to-peer learning and to follow the four core soil health principles:

    1) Keep the soil covered -- Cover crops are our friends and allies; avoid bare fallows;

  • S5 - E22: Encouraging a Hospitable Habitat for Soil Microorganisms with Dr. Ashley Jernigan of Virginia Tech, Pt. II

    S5 - E22: Encouraging a Hospitable Habitat for Soil Microorganisms with Dr. Ashley Jernigan of Virginia Tech, Pt. II
    Oct 28 2025
    Did you know soil microorganisms of all sizes and shapes need water, air, shelter, and care to function and thrive? Dr. Ashley Jernigan, assistant professor and director of Virginia Tech's Sustainable and Organic Vegetable Crops Production Lab, returns to talk with Jeff and Mary about what farmers and gardeners can do to encourage a hospitable habitat for soil microorganisms.

    As a soil ecologist, Ashley recommends keeping track of your soil organic matter level and its aggregate stability, and how these soil health indicators compare to native biological systems. Soils, like people, need quality food in diverse and complex forms (compost, green manures, plant roots, etc.). Similarly, farmers and gardeners should avoid leaving the soil naked and bare. Being gentle and reducing the intensity of tillage is also key to maintaining a comfortable environment for soil critters and not disrupting the structures and networks that soil organisms establish.

    We would encourage our listeners to visit Andy Murray's A Chaos of Delight: Exploring Life in the Soil website and tour the gallery of photos of different soil microorganisms.

    As always, we encourage you to cooperate with other farmers, graziers, and gardeners for peer-to-peer learning and to follow the four core soil health principles:

    1) Keep the soil covered -- Cover crops are our friends and allies; avoid bare fallows;
    2) Minimize soil disturbance -- Practice no-till or gentle tillage as much as possible in your field or garden ;
    3) Maximize living roots year-round -- to improve biodiversity, soil structure, and life in the soil; and

    S5 - E21: Regenerating Worn Out Soils with Dr. Ashley Jernigan of Virginia Tech, Pt. I
    Oct 14 2025
    Does your garden soil just fall apart in your hands? How do you regenerate and bring back life to worn-out soils? Dr. Ashley Jernigan, assistant professor and director of Virginia Tech's Sustainable and Organic Vegetable Crops Production Lab, in visiting with Jeff and Mary, advises doing your own test in your garden or crop field with a shovel.As someone who enjoyed digging soil pits as a seven-year-old, Ashley recommends sampling to a six-inch depth to get a sense of your soil's tilth and aggregate stability. If the soil does not have a good, varied crumbly structure, the soil's organic matter content and aggregate stability may be low. Therefore, feed your soil and soil animals to feed your plants to start the biological journey and bring back the life in the soil.If you have ever wondered what soil animals like springtails and soil mites look like, Dr. Jernigan developed a Soil Mesofauna: Who are They? resource guide to help. Ashley also highly recommends Andy Murray's Chaos of Delight: Exploring Life in the Soil website for wonderful photos and videos. As always, we encourage you to cooperate with other farmers, graziers, and gardeners for peer-to-peer learning and to follow the four core soil health principles: 1) Keep the soil covered -- Cover crops are our friends and allies;2) Minimize soil disturbance -- Practice no-till or gentle tillage in your field or garden as much as possible;3) Maximize living roots year-round -- to improve biodiversity, soil structure, and life in the soil; and4) Energize with diversity -- through crop rotation, farm enterprises, and/or livestock integration.More details about the Virginia Farm-to-Table Feast and Harvest Celebration scheduled for Saturday, October 25, 2025, from 4:00 to 8:00 p.m. at On Sunny Slope Farm in Rockingham, Virginia, can be found at https://virginiafarmtotable.org/2025vaf2tharvestcelebration/To enjoy recent 4 The Soil blog posts and additional soil health resources, please visit https://www.4thesoil.org/blog and https://www.virginiasoilhealth.org/.

  • S5 - E20: Soil Health beyond the Economic Rationale with Kasper Krabbe of Aarhus University, Pt. 2

    S5 - E20: Soil Health beyond the Economic Rationale with Kasper Krabbe of Aarhus University, Pt. 2
    Sep 30 2025
    Is the economic rationale of soil health always the top priority for farmers? Or, do other soil values rise to the top of farmers' minds, for example, having a healthy habitat for soil fungi? Kasper Krabbe, a doctoral student at Aarhus University in Denmark and a visiting guest scholar at Virginia Tech, returns to talk with Mary, Jeff, and Eric about his research into understanding farmers' intrinsic and extrinsic values in caring for soil.

    Kasper states that a deeper understanding of farmers' values and motivations is needed because of the degraded condition of agricultural soils globally. For instance, peer pressure to maintain and strive for tidy fields can inhibit experimentation with alternative minimum till systems and diverse cropping mixtures because of neighboring farmers' perceptions of certain aesthetics.

    The videos Kasper created of his interviews and interactions with cooperating Danish farmers as part of the Soil Values research initiative can be viewed at https://www.youtube.com/watch?v=oxwHRB9ybRM

    As always, we encourage you to cooperate with other farmers, graziers, and gardeners for peer-to-peer learning and to follow the four core soil health principles:

    S5 - E19: Agroecological Dynamics of Soil Health with Kasper Krabbe of Aarhus University, Pt. I
    Sep 16 2025
    When you close your eyes, how do you envision your farm and soil ecosystem? What ideals, values, and priorities are part of your vision and farm business model? Kasper Krabbe, a doctoral student at Aarhus University in Denmark and a visiting guest scholar at Virginia Tech, talked with Mary, Jeff, and Eric about these questions and his research interest in farmers' perceptions and decision-making. Kasper is particularly intrigued by the human and cultural elements of farming and how context informs and shapes the agroecological system and soil health of individual farms and regional farming. Kasper's ongoing inquiry into the agroecological dynamics of farming, soil health, and specific values-based business models aligns with the objectives of the European Union's Soil Values project https://soilvalues.eu/. Additionally, Kasper has created videos based on his interviews and interactions with cooperating Danish farmers. This sample Soil Values video is with a Danish farmer who owns and operates a community-supported agriculture farm https://www.youtube.com/watch?v=oxwHRB9ybRM As always, we encourage you to cooperate with other farmers, graziers, and gardeners for peer-to-peer learning and to follow the four core soil health principles: 1) Keep the soil covered -- Cover crops are our friends and allies;2) Minimize soil disturbance -- Practice no-till or gentle tillage in your field or garden as much as possible;3) Maximize living roots year-round -- to improve biodiversity, soil structure, and life in the soil; and4) Energize with diversity -- through crop rotation, farm enterprises, and/or livestock integration.More details about the Virginia Farm-to-Table Harvest Celebration scheduled for Saturday, October 25, 2025, from 4:00 to 8:00 p.m. at On Sunny Slope Farm in Rockingham, Virginia, can be found at https://virginiafarmtotable.org/2025vaf2tharvestcelebration/To enjoy recent 4 The Soil blog posts and additional soil health resources, please visit https://www.4thesoil.org/blog and https://www.virginiasoilhealth.org/.

  • S5 - E18: Round Bale Grazing for Soil Health with Dr. Summer Thomas, Pt. II

    S5 - E18: Round Bale Grazing for Soil Health with Dr. Summer Thomas, Pt. II
    Sep 2 2025
    Feeding hay to livestock in the winter is very expensive, and often results in a sacrifice lot where manure gathers. At the same time, manure is considered gold because of its nutrient content, ability to supply organic matter, and to build soil life. In this second episode, Dr. Summer Thomas, education and outreach specialist with the Virginia Soil Health Coalition, takes us on a deeper dive into her research on the benefits of round bale grazing and how it pertains to the four core soil health principles

    Summer explains how livestock and round bale grazing are land and soil health management tools for reducing machinery costs, better distributing manure and essential nutrients across pastureland, and truly energizing the system with biodiversity.

    Overall, round bale grazing is a sound management practice that leads to healthy soils, healthy plants, and healthy animals.

    As always, we encourage you to cooperate with other farmers, graziers, and gardeners for peer-to-peer learning and to follow the four core soil health principles:

    1) Keep the soil covered -- Cover crops are our friends and allies;
    2) Minimize soil disturbance -- Practice no-till or gentle tillage in your field or garden as much as possible;
    3) Maximize living roots year-round -- to improve biodiversity, soil structure, and life in the soil; and
    4) Energize with diversity -- through crop rotation, farm enterprises, and/or livestock integration.

    S5 - E17: Everything Good Starts with the Soil with Dr. Summer Thomas, Pt. I
    Aug 19 2025
    Everything good starts with the soil and a conservation stewardship mindset. In the 101st episode, Dr. Summer Thomas, education and outreach specialist with the Virginia Soil Health Coalition, explains how agriculture and soil health are good for everyone. As a third-generation farmer from Delaware, former watermelon queen, a trained soil scientist and educator, and an overall advocate for agriculture, Summer shares some of her earliest experiences of 4-H and FFA with Jeff, Mary, and Eric in public speaking, youth education, and land stewardship.

    These early education and outreach experiences were a launch point for her passion for agriculture and career pursuit.

    Summer emphasizes that soil health and agriculture provide many positive community connections and must be fun for the next generation of farmers. Additionally, soil health is foundational to resilient farm businesses and systems.

    As always, we encourage you to cooperate with other farmers, graziers, and gardeners for peer-to-peer learning and to follow the four core soil health principles:

    1) Keep the soil covered -- Cover crops are our friends and allies;
    2) Minimize soil disturbance -- Practice no-till or gentle tillage in your field or garden as much as possible;
    3) Maximize living roots year-round -- to improve biodiversity, soil structure, and life in the soil; and
    4) Energize with diversity -- through crop rotation, farm enterprises, and/or livestock integration.

    Yes, soil health is a great conversation starter. We encourage everyone to have a five-minute conversation about soil every day because we can all be 4 The Soil and for the future!
