Regenerative Agriculture Podcast

In this episode of the Regenerative Agriculture Podcast, John interviews Dr. Arden Andersen, who holds a Ph.D. in Agriculture and Biophysics. In this conversation on biophysics, John and Dr. Andersen explore topics such as the role of calcium, soil compaction, pest pressure, and more from the perspective of biophysics and energy. Dr. Andersen's career in agriculture started in childhood on his family's holistically managed dairy farm. This experience provided him with the daring to question accepted science and to forge new paths. While earning a bachelor's degree in agriculture, Dr. Andersen noted that his father's herd suffered from none of the dairy diseases he was studying, allowing him to draw a correlation between disease immunity and herd health. Through further study, he determined that immunity is influenced by nutrition and that this principle is the same for plants and mammals, including humans. Dr. Andersen dove into the world of biophysics, learning from pioneers such as Dr. Philip Callahan, Dr. Dan Skow, Dr. Fritz-Albert Popp, and Dr. Carey Reams, all of whom have had a vast influence on the fields of biophysics and energetics. Dr. Andersen reiterates the importance of soil calcium and functional biology to plant health, but from the perspective of the energetic signals the minerals and plants are carrying. He says that calcium is the foundational messenger that allows communication within the plant/soil system at the cellular level and that if calcium is ample, foliar sprays become much more successful and effective. Similar to putting a cheater bar on the end of a wrench to gain additional torque, foliar sprays add the last touches of power to a plant that has a sufficient soil base of nutrition. John and Dr. Andersen discuss clay chemistry and clay aging and how this impacts soil compaction. Clay aging is a term derived from the petroleum industry and it describes the process that develops when enough potassium chloride has been applied into the clay matrix to drive out the calcium and magnesium. At this point, the clay collapses and hardens at the molecular level, and soil compacts easily. Dr. Andersen warns that high-powered artificially produced electromagnetic frequencies can exhaust antioxidants and essential nutrients. To overcome the negative impact of these frequencies, plants must have a solid foundation of biology to derive nutrition from the soil. He states that plant growth is restricted by energetic limitations, and not by time. The subtle energies that drive information exchange between and within living cells determine how fast that cell can grow. An insufficiency of harmonic energy can lead to an insufficiency of molecular movement. By harnessing these energetic life forces, plants can be grown to maturity much faster. Dr. Andersen notes that plant genetic information is carried by an energetic signature that determines the physical chemistry and describes how stray energetic current causes both plant and animal disease by interfering with the central energy signature of that living organism. Dr. Andersen stresses the importance of being in tune with the soil, plants, and life in the field. He reviews the scientific component of communication between plants and the human heart and mind, stating that it's the life force in plants that we are gaining from the food we eat which keeps us alive. Listen to this episode to explore how understanding energetic life forces can provide the key to gaining enhanced performance from our crop genetics and environment.

In this episode of the Regenerative Agriculture Podcast, John Kempf interviews Dr. Jill Clapperton, a plant physiologist with an intuitive understanding of the workings of the rhizosphere and an abundance of metaphors that clearly explain these mechanisms. Dr. Clapperton worked as the Rhizosphere Ecologist at AgriFood Canada and more recently started her own company, Rhizoterra, where she researches agronomic practices and develops technologies for scientific on-farm decision making. John and Dr. Clapperton delve into the science of the rhizosphere, discussing how the plant drives and controls the actions that transpire there. Each plant species exudes its own signature of carbon compounds, including sugars, amino acids, lipids, nucleic acids, and other compounds, which Dr. Clapperton refers to as 'carbon skeletons'. The plant then works with the rhizosphere to add the 'meat' of mineral nutrients, oxygen, hydroxyl groups, and more to make the long or short carbon chain 'skeletons' functional. Dr. Clapperton describes the function of these carbon chains as having multiple "command lines" or calls to action, available in their service of the plant. These actions include things such as calling in nematodes to parasitize insect larvae that are feeding on the roots of the plant, or calling in nitrogen-fixing bacteria if the plant is a legume. Dr. Clapperton also details how the nutrient density of a crop varies based on the cover crop species grown prior to the crop. The root exudates of different plant species develop entirely different colonies of soil fauna to bind the nutrition they need and deliver it to the plant. Because of this, a multi-species cover crop will provide a greater number of different nutrients available in the soil to the following crop. Dr. Clapperton outlines a detailed list of the crops with a compatible rhizobium; for example corn and canola rhizobia are incompatible. Dr. Clapperton also describes the various forms that photosynthates can take within the plant structure, underscoring the need for a robust photosynthesis cycle. As a metaphor, Dr. Clapperton suggests it's like starting with the train engine, which is the photosynthate, and then continuing to add cars onto the train by building these very different molecules from photosynthesis. In the complicated plant/mycorrhizae relationship, the mycorrhizae may need slightly more acidic root exudates in order to grow its hyphae, so it gathers minerals and transports them into the plant, trading them for more amino acids and carboxylic acids and organic acids. Scenarios occur where secondary plant compounds used for fighting disease are made, and if the plant doesn't need them, they will be broken down and redeveloped into other compounds. In addition, Dr. Clapperton describes how microbes seem to "hoard" amino acids and mineral elements and that if the soil fauna contained only microbes they would out-compete the plant for nutrients. Thus, predator/prey relationships come into play in which the plant calls for other organisms such as bacteria and fungi to eat and digest the microbes, making the nutrients being held by the microbes available for the plant. She describes the methods plants use to continually assess their needs and send chemical signals to the rhizosphere. For example, if there's an aphid on the leaves, the plant sends a signal to ramp up secondary metabolite production to lignify the leaves. Dr. Clapperton's latest research focuses on maintaining a preventative environment in plants, finding and replicating the factors that lead to plant resistance to disease and pest attack. For example, nematodes trying to puncture the roots of an onion crop can be parasitized by fungi, and insects trying to eat the roots can be preyed upon by nematodes. Dr. Clapperton is researching these interactions and learning how we can develop the conditions for them to occur. Learn more about her research on the Rhizoterra website.

In this episode of the Regenerative Agriculture Podcast, John interviews Dr. Norman Uphoff, who was the director of the Cornell International Institute for Food, Agriculture and Development from 1990 to 2005, and is currently Professor Emeritus of Government and International Agriculture at Cornell University. In this episode, Dr. Uphoff relates how he learned about the System of Rice Intensification in 1993 when he was sent to Madagascar as part of an initiative led by Cornell University to develop a program to increase rice yields and help rural development. There Dr. Uphoff learned about the System of Rice Intensification, a method of growing rice that was claimed to increase yields dramatically that had been developed by a French Jesuit priest named Father Henri de Laulanié. Dr. Uphoff was skeptical that the full extent of the reported yields was true but thought the method merited further investigation and developed a plan for the Cornell program to run trials. The System of Rice Intensification focuses on providing plants with oxygen, photosynthesis, and soil biology, involving methods that were not the norm in the growing practices used in rice production, but that consistently increased yields from 50 to 200%. Farmers using this system saw many more tillers, greater root growth, and plants that stayed green longer. The plants intercepted more sun, gave higher yields, and were more resistant to pests and diseases. They didn't bend over in storms as easily and could withstand water stress and drought conditions. Dr. Uphoff describes how he trialed the method, demonstrating it on the ground in Madagascar and then expanding it to other countries. Dr. Uphoff describes the practices used in the SRI method for growing rice and then shows how those same methods, renamed to System of Crop Intensification (SCI), can work for other crops. One key characteristic of SRI and SCI is the use of compost instead of commercial fertilizers. Dr. Uphoff describes the situations in which compost shows the same efficacy as commercial fertilizer. This episode is a gem from one of the pioneers who achieved wide promotion of regenerative growing practices in an era when those practices were much less popular than they are today.

SRI plant on right was transplanted from the nursery at 13 days into SRI growing conditions, while the plant on left was removed from nursery at 52 days for transplanting at usual time in Cuba. 43 tillers vs. 5 tillers; as important are the differences in size and color(!) between the two plants.

In this episode of The Regenerative Agriculture Podcast, John interviews Jason Mauck, an Indiana corn, soybean, wheat, and hog producer who thinks outside the borders of convention and who has pioneered a number of innovative practices. Jason describes the guiding force behind his experiments and innovation as the desire to gain as much control over the variables in farming as possible. Rather than embracing traditional planting and application methods, Jason experiments with new approaches to farming, measuring whether they give him more resilience and control over his inputs and yields. Jason is passionate about relay cropping, the practice of having a second crop growing before the first crop is harvested. An example of this is a cool grass cereal such as wheat or rye planted with a summer annual of corn or soybeans. He describes his experimentation with this approach, from the original plan of planting two crops together and doing all of the same things he would do for each crop planted separately, to his current understanding of the equilibrium needed to successfully bring both crops to maturity with a productive harvest. He has experimented with modifying the width of the rows to accommodate the needs of both growing crops. He also discusses the role manure management plays in his farming operation, and how his goal is to use this source of nitrogen to decrease his dependence on off-farm inputs. In this interview, Jason talks about seldom discussed ideas, such as the phi angle of plant expression, which he describes as coordinating plantings so the solar angles reach the intercropped species. Also, he describes how a farmer can influence 6-ear corn or 200-seed wheat by following the principles of the Golden Mean. Jason talks about the conventional rationale of farmers, by which seed is planted with high hopes, given plenty of nitrogen and all the "by-the-book" fungicide and herbicide applications, and how his approach differs. Alternatively, he thinks of maximizing his yield with on-farm inputs and minimal costs, as well as considering the benefits of water absorption and soil biology the planting adds to the ecosystem. Jason also talks at length about farm economics, and how to increase the contribution margin by decreasing the input costs while employing methods to increase yields.

In this episode of the Regenerative Agriculture Podcast, John interviews French agronomist, Olivier Husson, whose pioneering work on soil pH and redox potential provides a groundbreaking look at what goes on within the soil. Olivier has focused a large part of his research on the study of reduction-oxidation (redox) in rice production, where the crop is grown in paddies in anaerobic conditions. These conditions are ideal for the study of Eh. Eh, the short notation for redox potential, is a measurement of the availability of electrons, whereas pH is a measurement of the availability of protons. In order to gain a full picture of the soil's nutrient profile, we need to assess both the pH and the redox potential at the same time. In this interview, Olivier details: the difference between Eh and pH how the Eh profile changes based on photosynthetic activity how electrons in the soil are key to reversing oxidation and absorbing nutrition from soil mineral reserves how Eh determines water absorption capacity how the whole plant is regulated by the redox signal the Eh and pH parameters that are present when pathogenic fungi, bacteria, and viruses manifest in a plant and cause disease. John and Olivier have also presented on the topic of redox in a 6-hour course format, including graphs and visuals, which is available as a part of the Regen Ag Academy.

Claudia Carter, Executive Director of the California Wheat Commission, discusses the marketability of wheat and the development of wheat varieties with increased quality and nutritional value. They explore topics such as biofortification, the function of protein content in baking, and the challenges faced by growers in the grain industry.

In this episode of the Regenerative Agriculture Podcast, John Kempf interviews plant pathologist Dr. James White of Rutgers University, whose work provides a new perspective on plant pathology, susceptibility to soil-borne pathogens, and plant absorption of nutrients. Dr. White explains how endophytes, non-pathogenic fungal and bacterial organisms present in all plants, are a mechanism by which plants can absorb complete molecules, internalize and propagate soil-borne microbes, and nullify pathogenic organisms. In the interview, Dr. White describes how plants cultivate microbes at the meristem, or root tip, where exudates are created. In this zone, these endophytes further attract and cultivate microbes from the soil in the rhizophagy cycle, from rhizo- meaning 'root' and -phagy meaning 'eating'. Through this process, plants attract and internalize soil-borne microbes. The microbes are then internalized by the plant and deliver nutrients from the soil directly to the roots. Dr. White relates how this endophytic process encourages oxidative interaction, fostering hardier, more stress-tolerant plants, and how nitrogen applications and fertilizer decrease the incidence of these endophytes, leading to disease-susceptible crops. In cotton culture, for example, the practice of seed de-linting prior to planting effectively destroys the endophytes present on the seed. Besides stimulating growth and stress tolerance within the seedling by bringing nutrients from the soil, endophytes also colonize pathogenic fungi, resulting in their reduced virulence. The endophytes don't kill the fungi, but rather they colonize and weaken it so disease incidence is greatly reduced. In some cases, those pathogenic fungi will actually become endophytic fungi in the plant, as in the example of Fusarium oxysporum. Once Fusarium oxysporum is colonized by the endophytic bacteria, it grows more slowly and onto the plant leaf surface. However, as long as the endophytic bacteria are also present, the Fusarium organism doesn't cause disease. Dr. White describes how researchers are just beginning to understand the significance of endophytic functions and the rhizophagy cycle. In the future, we are enabled to be more cognizant of what we're doing to the soil and plant microbiome in the process of cultivating plants. In this absorbing conversation, John and James cover the science behind: How plants absorb living microbes How endophytic microbes change potential pathogens' behavior to provide plant nutrients rather than cause disease How plants propagate soil derived-microbes Why cultivated varieties are more disease-susceptible than wild varieties and how this can be reversed How plant breeding processes can contribute to the loss of beneficial microbes on the seed coat More details that will change the way you think about seeds, planting, disease, and nutrition Resources:Research Paper: Rhizophagy Cycle: An Oxidative Process in Plants for Nutrient Extraction from Symbiotic Microbes Research Article: Pest Management Science: Review: Endophytic microbes and their potential applications in crop management Learn more about the rhizophagy cycle in a new 6-hour course from James White at https://www.academy.regen.ag/understanding-rhizophagy/ Support For This Show This show is brought to you by AEA, helping professional growers make more money using regenerative agriculture since 2006.

In this podcast interview, host John Kempf and Canadian farmer Derek Axten discuss Derek's path to profitable farming practices. This journey started in 2007 when Derek made a trip to Dakota Lakes Research Farm where he witnessed soil health and water infiltration levels beyond which he knew were possible. In subsequent trips to Dakota Lakes and visits to Gabe Brown's ranch, Derek learned soil and crop management principles which he's adapted to his own farm. In this episode, learn about the methods and systems Derek has applied and how they've changed the trajectory of his farm from soil health and economic perspectives. Derek describes his system of inter-cropping and the management practices he employs to increase soil infiltration. He and John also discuss controlled traffic farming, Derek's liquid fertilizer regimen, and decreasing the use of applied nitrogen and other synthetic inputs. Listen to learn how Derek approaches: Soil management tactics and results Water infiltration Intercropping with two or more crops Fertility applications and compost teas Tillage Controlled traffic farming Support For This ShowThis show is brought to you by AEA, helping professional growers make more money using regenerative agriculture since 2006.

Thank you for permitting the interruption…now, on to the show notes! In this episode of the podcast, John interviews Dan Kittredge, the Executive Director of the Bionutrient Food Association, whose development of sustainable agriculture techniques has connected him to farmers worldwide. In this interview, John and Dan delve into the science of growing crops as it relates to human nutrition, describing how agricultural production practices can produce a better nutrient profile in our foods and the potential this holds for human health. He explains why a balanced, as well as a higher nutrient density in crops, is desirable. He discusses the complex relationships between the sun, soil, and plants that lead to these higher and balanced levels of nutrition. Dan explains that across the same food types, i.e., all carrots, wheat, milk, etc., there can be discrepancies in the reported nutritional values and how nutritional data on food packages can be wildly incorrect. Over the past few years, Dan has been working on the development of a BioNutrient Meter, a handheld spectrometer which tests mineral levels in fruits and vegetables. Dan describes the science of spectroscopy, which is based on the frequencies emitted by each chemical element --this same technology helps scientists and astrophysicists determine the composition of stars six light-years away in our solar system. By measuring the frequencies and light particular elements emit, they can measure the percentage of hydrogen, helium and other gases. With the science of spectroscopy, and other new technology, Dan and his team at the BioNutrient Food Association have built a first-generation model of a miniaturized consumer-priced spectrometer for testing the nutrient levels in crops. Listen to this provocative conversation between two pioneers who are truly passionate about growing food as medicine to learn: How Dan founded BFA, and how this non-profit provides support and education for farmers about the use of biological systems The science behind plant resistance to insects, and why these resistant crops make good, in fact better, food for humans. The differences in nutrient density between instances of the same crop when grown on different soil under different conditions How soil and plant health correlates to nutrient density How the compounds that correlate with flavor and aroma are those that make the plant indigestible for an insect or disease The science of spectroscopy, and how the new BioNutrient Meter works Resources The BioNutrient Food Association is having their annual Soil & Nutrition Conference in Massachusetts on November 13 to 17, 2019.

In this episode of The Regenerative Agriculture Podcast, John Kempf interviews Walter Jehne, an Australian soil microbiologist and the Director of Healthy Soils Australia. Walter has written and taught extensively about the earth's soil carbon sponge and hydrology as they relate to climate change. Walter provides context for the extreme weather events we are experiencing, and clearly identifies the role that water plays as a climate regulator. He describes how we can manage water to safely and naturally cool the planet and regulate climate change. Walter has developed a perspective on the impact that farmers can have on the climate that is different than the dominant narrative on carbon sequestration. While carbon sequestration is an important piece of the puzzle, Walter explains how managing the way our soils retain and hold water has a much bigger impact due to the way the hydrological system functions as a regulator for the planet. Walter describes how specific tactics in the management of water in our soils can reduce extreme weather events. Here are a few things Walter and John discuss in this engaging episode: Why rising co2 levels are a symptom, rather than the cause, of the abnormal warming of the past 250 years How improving the soil's water-holding capacity contributes to a more stable climate The foundational principles of atmospheric physics and the climate The effect of land degradation on the hydrological dynamics of the planet How regenerating the soil carbon sponge is the critical bridge between carbon management and hydrology management How increasing photosynthesis and "green longevity" is the key to restoring the hydrological balance, thus restoring climate balance and reducing extreme weather events Support For This Show This show is brought to you by AEA, helping professional growers make more money using regenerative agriculture since 2006.
