996: The Plant Nutrition Revolution Has Arrived

How we are finally figuring out Plant nutrition with Landen SchillingIn this month's Seed Chat, Greg Peterson and Bill McDorman welcome Landon Schilling of Sacred Soil Solutions to explore the emerging science of rhizophagy, the process by which plants consume microbes for nutrition. The conversation examines how endophytes, fermentation, compost, and seed saving may work together to improve plant health, resilience, and flavor. They also discuss practical ways gardeners can introduce beneficial microbes into their gardens while highlighting the rapidly evolving research that is reshaping our understanding of soil biology and plant nutrition.Our Guests: Landon Schilling is the founder of Sacred Soil Solutions. He is focused on bringing optimal and approachable microbe inputs to gardeners and homesteaders, while also teaching farmers in the American West how to implement soil building solutions at scale.And Bill McDorman has committed his life to community-based seed stewardship. In 1984, he started Seeds Trust High Altitude Gardens, a bioregional mail order seed company that he ran for 28 years. He authored the book Basic Seed Saving in 1994, and in 2010 Bill and his wife, Belle Starr, founded Seed School.Key TopicsRhizophagy (root-eating process)Endophytes and plant microbiomesSoil microbiologySeed saving and local adaptationHorizontal gene transferFermentation for microbial cultivationCompost and fungal soil biologyMicrobe Master MixEffective Microorganisms (EM/EM1)Dr. James F. WhiteJohn Kempf's Plant Health PyramidDr. Christine JonesBiochar and Terra PretaSacred Soil SolutionsKey Questions AnsweredWhat is rhizophagy?Rhizophagy is the process by which plants absorb living microbes through their root tips, consume many of them for nutrition, and release others back into the soil, creating a dynamic relationship between plants and soil biology.What are endophytes?Endophytes are beneficial bacteria and fungi that live inside plant tissues without causing disease. They become part of the plant's internal microbiome and contribute to nutrient cycling, resilience, and overall plant health.Why is this research changing how we understand plant nutrition?Emerging research suggests healthy plants obtain much of their nutrition by consuming living microbes rather than relying solely on dissolved minerals in the soil, expanding traditional models of plant nutrition.Why are locally saved seeds so valuable?Seeds saved in a local environment gradually adapt genetically to regional growing conditions. Local microbial communities appear to undergo similar adaptation, potentially increasing plant vigor over time.How can gardeners introduce beneficial microbes?Gardeners can inoculate seeds, apply microbial solutions as foliar sprays, drench transplant roots, build high-quality compost, and encourage living soil ecosystems through mulch and cover crops.Why are microbial fermentations useful?Fermentation allows gardeners to rapidly multiply beneficial microorganisms that can be applied efficiently to seeds, soil, and foliage while adapting to local growing conditions.Does treating seeds with microbes improve plant performance?According to Landon Schilling's experience, treated seeds often produce stronger root systems, healthier foliage, improved nutrient uptake, greater vigor, and enhanced flavor.Is feeding the plant different from feeding the soil?The discussion suggests both are important, but directly supporting plant microbiology may allow healthier plants to build better soil through root exudates and microbial partnerships.How does drought affect soil microbes?Dry soils reduce microbial activity. Maintaining mulch and consistent soil moisture helps preserve beneficial microbial populations.Can microbial communities adapt to new environments?Yes. Through horizontal gene transfer and rapid reproduction, microbial populations can adapt to local conditions much faster than plants themselves.Episode HighlightsGreg celebrates the Urban Farm Podcast approaching its 1,000th episode.Bill McDorman introduces the emerging science of rhizophagy and why it has changed his perspective on gardening.Landon explains how plants consume microbes through root tips rather than relying solely on dissolved nutrients.The conversation explores how endophytes become part of a plant's internal immune and digestive systems.Bill shares dramatic improvements after using microbial treatments on greens grown in sandy soil.The panel discusses microbial fermentations as an accessible alternative to intensive compost production.Audience questions cover drought, raised beds, honey versus molasses, wheat adaptation, and sourcing microbial inoculants.The episode concludes with a discussion about nature's intelligence, seed adaptation, and the intriguing tradition of placing seeds in one's mouth before planting.Calls to Action & ResourcesAttend future live Seed Chats — https://seedchat.orgListen to previous Seed Chats — https://urbanfarmpodcast.comLearn about Sacred Soil Solutions — Contact Landon Schilling directly for information on Microbe Master Mix and educational resources.Recommended ResearchDr. James F.

995: How Illegal Street-Side Water Harvesting Sparked Community Transformation

with Brad Lancaster & Andrew MillisonIn this Episode - What begins as a simple effort to redirect stormwater becomes a powerful story of ecological restoration, community organizing, and policy change. Brad Lancaster and Andrew Millison discuss how a grassroots, initially "pre-legal" water harvesting project transformed neighborhoods in Tucson, inspired new city policies, and is now influencing communities across the Southwest. They explore how small interventions can create lasting cultural shifts, why regenerative change requires generations of stewardship, and how anyone can become a catalyst for positive change in their own community.Our Guests: Brad is the author of the books Rainwater Harvesting for Drylands and Beyond, the creator of HarvestingRainwater.com, and co-founder of Neighborhood Foresters.org. These converge through his neighborhood’s rain-irrigated native food forestry efforts in downtown Tucson, AZ. Their work has planted over 1,800 native food-bearing trees and thousands of multi-use understory plants solely watered by the 1.25 million gallons of stormwater they planted in streetside- and in-street rain gardens. Andrew Millison is an educator and founder of Oregon State University’s Permaculture Design program. He has travelled the Earth documenting impactful stories of land regeneration on his popular YouTube channel, which boasts over 100 million video views. In his 30-year career in Permaculture, he has designed and consulted on numerous projects throughout the world.Key TopicsStreet-side water harvestingBrad LancasterAndrew MillisonTucson neighborhood restorationCommunity-led ecological designRainwater harvestingUrban heat island mitigationNative food forestsWater policy reformRegenerative community developmentGreen infrastructureEarth Repair FundNeighborhood stewardshipPermaculture designKey Questions AnsweredHow did an illegal curb cut become a model for public policy?A neighborhood experiment redirecting street runoff into planted basins demonstrated measurable environmental and community benefits. Those results convinced city officials to legalize and eventually promote the practice, creating a model now spreading to other cities.What problems does street-side water harvesting solve?It reduces flooding, cools neighborhoods, slows traffic, supports native ecosystems, grows food, increases biodiversity, improves walkability, and strengthens neighborhood relationships—all using rainwater that previously became waste.Why is community participation more important than infrastructure?Infrastructure creates opportunity, but long-term success depends on residents becoming active stewards. Cultural change happens when people continually care for and improve the systems they've created together.How has Tucson changed over the past 30 years?What was once a hot, barren streetscape has become a shaded urban forest filled with native plants, birds, pedestrians, cyclists, and community gathering spaces.Why focus on native plants?Native species require less irrigation, survive harsh conditions, support local wildlife, and create resilient landscapes that continue thriving even when maintenance decreases.What does "pre-legal" mean?Rather than breaking rules for the sake of rebellion, Brad describes testing practical solutions before regulations existed. Successful demonstrations then became the basis for changing policy.How do you convince government agencies to support innovation?By solving their existing problems—flooding, crime, heat, traffic, maintenance costs—and collaborating with receptive allies inside government rather than making demands.When does a project become a cultural movement?When it measurably improves people's daily lives, inspires widespread participation, changes public policy, and motivates others to adapt the ideas within their own communities.Why did Andrew Millison choose to document this story?Because it represents a proven, decades-long example of regenerative change that others can replicate, offering practical hope instead of theoretical solutions.What mindset shift do the speakers hope listeners experience?To begin seeing neighborhoods as living watersheds full of opportunities for regeneration, rather than fixed infrastructure that cannot be improved.Episode HighlightsA neighborhood experiment in harvesting street runoff evolved into city-approved infrastructure and inspired policy changes beyond Tucson.Water harvesting became a catalyst for cooling neighborhoods, restoring wildlife habitat, calming traffic, and building stronger communities.Native food forests transformed once-barren public rights-of-way into productive community commons.Brad Lancaster explains how changing policy requires collaboration, persistence, and demonstrating successful models.Andrew Millison shares why documenting proven regenerative projects creates hope and motivates action.The discussion explores how infrastructure can become a tool for cultural transformation.Both guests emphasize that regenerative work is lifelong, requiring continual community participation rather than one-time projects.Listeners are encouraged to identify their own community's "acupuncture point"—the small intervention capable of creating widespread positive change.ResourcesWatch the documentaryFundraising documentary on Brad Lancaster's Tucson water harvesting projectLearn Rainwater HarvestingHarvestingRainwater.comSupport the ProjectEarth Repair Fund crowdfunding campaignExplore Native Urban ForestryNeighborhoodForesters.orgLearn PermacultureOregon State University Permaculture ProgramBooksRainwater Harvesting for Drylands and Beyond by Brad LancasterYouTubeAndrew MillisonBrad LancasterPodcast Show Notes Visit www.urbanfarm.org/TucsonWaterHarvesting for the show notes on this episode, and access to our full podcast library!

994: Diving Deeper on episode 993 with Farmer Greg

In this special commentary episode, Farmer Greg reflects on his conversation with Shelby Maldonado and Leeza Chen of the Appalachian Grower Seed Collective. He explores how the Southeast lost much of its regional seed-growing infrastructure, why COVID-19 exposed the fragility of modern seed supply chains, and what it takes to rebuild resilient, locally adapted seed systems. Greg highlights the importance of bioregional seed stewardship, community collaboration, and becoming a "seed ancestor" by saving and sharing seeds. The episode is both a call to action and a vision for strengthening local food security through regional seed sovereignty.Key TopicsAppalachian Grower Seed CollectiveSeed sovereignty and regional resilienceCOVID-19 seed shortagesLocal seed production infrastructureSeed saving traditionsBioregional seed adaptationSouthern heirloom varietiesCommunity seed cooperativesClimate resilience in agricultureShared seed processing equipmentUtopian Seed ProjectLocal food securitySeed stewardshipBecoming a seed ancestorKey Questions AnsweredWhy did the Southeast largely stop producing its own seeds?Over time, seed production became concentrated in other regions and large commercial seed companies. Farmers shifted from saving seeds to purchasing them annually, causing local seed knowledge and infrastructure to fade.What did the COVID-19 pandemic reveal about the seed supply chain?When seed inventories sold out during the pandemic, many growers realized they were dependent on distant suppliers and vulnerable to disruptions beyond their control.Why are locally adapted seeds so valuable?Seeds selected over multiple seasons in the same region naturally adapt to local soils, climate, pests, and weather patterns, often outperforming varieties developed elsewhere.What is bioregional seed adaptation?Bioregional adaptation is the ongoing process of selecting and saving seeds that thrive under local growing conditions, creating increasingly resilient crops over successive generations.How did the Appalachian Grower Seed Collective get started?The collective began with ten farmers, shared seed-cleaning equipment housed in a mobile trailer, grant funding, and a year dedicated to building trust before launching seed production.Why does the collective only steward seeds grown locally for at least three years?Three growing seasons provide enough time for varieties to begin adapting to regional conditions, strengthening their long-term resilience and performance.How can individual gardeners begin preserving seed diversity?Anyone can save seeds from plants they love, share them with neighbors, and begin creating a regional seed legacy—even without large-scale infrastructure.Why should every region develop a seed collective?Regional seed collectives create local agricultural resilience, preserve genetic diversity, strengthen community relationships, and provide insurance when commercial supply chains fail.Episode HighlightsCOVID-19 exposed how dependent many local farmers are on distant seed suppliers.Modern local food systems are only as resilient as their seed sources.Seed saving knowledge disappeared gradually as commercial seed purchasing became the norm.Trust-building among growers proved just as important as equipment or funding.Every growing season becomes a selection event that strengthens locally adapted genetics.Gardeners can become the first "seed ancestor" in a new regional seed lineage.Seed collectives create practical infrastructure that complements—not replaces—the commercial seed industry.Building resilient food systems begins with communities stewarding their own seeds.Calls to Action & ResourcesListen to Episode 993 - https://urbanfarm.org/seedcollectiveLearn about the Appalachian Grower Seed Collective - https://utopianseed.org/storeConnect with the Urban Farm Podcast - https://urbanfarm.orgEmail Farmer Greg - podcast@urbanfarm.orgInterested in starting a seed collective?Reach out to the Appalachian Grower Seed Collective to learn from their experience and begin building seed resilience in your own region. leeza@utopianseed.orgVisit www.urbanfarm.org/993 for the show notes on this episode, and access to our full podcast library!

993: Building Regional Seed Sovereignty Through Community

The Appalachian Growers Seed Collective w/ Shelby Mandonado and Leeza ChenIn this Episode Shelby Mandonado and Leeza Chen share the story behind the Appalachian Growers Seed Collective, a collaborative network of farmers producing and stewarding locally adapted seeds for the Southern Appalachian region. They discuss why regional seed production matters, how climate change makes local adaptation increasingly important, and how farmers can reclaim seed sovereignty by saving and sharing seeds. The conversation explores the practical realities of launching a seed collective, preserving heirloom varieties, and strengthening local food systems through collaboration rather than competition. It is an inspiring discussion about resilience, biodiversity, and the long-term power of community-grown seeds.Our Guests: Shelby is a farmer, organizer, and mother with a passion for collaborative models of community building based around our shared love of the land. And Leeza is a seed farmer near Asheville, North Carolina. She is inspired by the way seeds are both deeply personal and powerfully political, often leaning on them as a lens to understand our connection to the land, culture, and sovereignty.Key TopicsAppalachian Growers Seed CollectiveShelby MandonadoLeeza ChenSouthern Appalachian seed stewardshipBioregional seed adaptationSeed sovereigntyLocal food systemsCommunity-based seed productionSeed farmingClimate resilience in agricultureUtopian Seed ProjectHeirloom and heritage crop preservationFarmer collaboration and shared equipmentSeed saving as cultural preservationKey Questions AnsweredWhat is the Appalachian Growers Seed Collective?A regional network of approximately ten farmers who collaboratively grow, steward, package, and sell locally adapted seed varieties while sharing equipment, knowledge, and resources.Why are locally adapted seeds so important?Seeds grown and selected in a specific region become better adapted to local climate, weather patterns, soils, pests, and diseases, improving reliability for future growers.What is a seed farmer?A seed farmer allows crops to complete their full life cycle, harvesting mature seed instead of edible produce, then cleaning, testing, and packaging seed for future planting.Why has on-farm seed saving declined?Commercial seed industry consolidation has led many growers to purchase seed annually rather than saving their own, reducing regional adaptation and local seed resilience.How did the COVID-19 pandemic influence the collective?Seed shortages during the pandemic exposed vulnerabilities in the food system and highlighted the need for local seed production and regional seed independence.How was the collective started?The founders secured a grant, purchased shared seed-processing equipment, built a mobile processing trailer, and spent significant time developing trust, shared values, and collaborative systems before expanding production.What makes Southern Appalachian seed production unique?The region's humid climate presents challenges rarely addressed by traditional seed-saving literature, requiring local experimentation and farmer-to-farmer learning.How can others start a regional seed collective?Begin with trusted growers, define shared values and goals, develop a complementary seed collection, share resources, and grow at the "speed of trust."How does the Utopian Seed Project support the collective?The nonprofit evaluates diverse crop varieties through research and field trials, then shares promising selections with the collective for regional seed production and distribution.What role does seed stewardship play in climate resilience?Saving seed from plants that survive local stresses gradually builds populations better adapted to changing environmental conditions.Can someone without a farming heritage become a seed steward?Absolutely. Every seed saver can become the first generation of a new seed lineage by preserving, sharing, and passing seeds to future growers.Episode HighlightsThe collective includes about ten farmers working together to grow, process, and market locally adapted seeds.Seeds are selected only after proving themselves through multiple growing seasons in Southern Appalachian conditions.COVID-19 seed shortages revealed how dependent local food systems are on distant commercial seed suppliers.Shared equipment, including a mobile seed-processing trailer, allows small farmers to access professional seed-cleaning tools.Trust-building, shared meals, and collaborative decision-making are considered just as important as technical farming skills.Climate change makes regional seed adaptation increasingly valuable for future food security.Every heirloom seed carries generations of cultural history, family traditions, and local knowledge.Anyone can become the first ancestor in a new seed-saving tradition by simply beginning to save and share seed.ResourcesAppalachian Growers Seed Collective Store — https://utopianseed.org/storeUtopian Seed Project — https://utopianseed.orgReal Seeds ZigZag Winnower Plans — https://www.realseeds.co.ukConnect with Leeza Chen — leeza@utopianseed.orgRecommended Book - The Seed Garden by Jared ZystroFollow Utopian Seed Project — Instagram, Facebook, and the Utopian Seed Project mailing list for breeding trials, research, and seed releases.Visit www.urbanfarm.org/SeedCollective for the show notes on this episode, and access to our full podcast library!
