CureSoil

CureSoil is one of only five Demeter Certified Biodynamic compost operations in the United States, producing biologically complete compost from our base in the heart of West Marin, CA. Our philosophy is simple: treat the soil, not the symptoms.

 

Founded on 25+ years of organic and biodynamic practice, CureSoil bridges rigorous soil science with Biodynamic principles. We integrate the soil food web, mineral balancing, and trained soil microscopy to build compost that restores living biology to depleted ground. Every batch is made to deliver the fungal-to-bacterial balance, diversity, and microbial vitality that the Biodynamic preparations were designed to amplify.

 

We work alongside growers across the region — vineyards, market farms, turf managers, and home gardeners — helping them shift from input dependence toward genuine soil health. Whether through bulk compost, extracts, or our small-format Satellite Pack for home gardens, our aim is the same: regenerate the biology that makes nutrient-dense food and resilient landscapes possible.

 

We're honored to be part of the Demeter community and the growing Biodynamic movement.

SeaCoast

Compost

SeaCoast Compost began as a dream to transform the waste from Oregon’s three iconic industries, Fishing, Dairy and Timber, into a life-giving Biodynamic soil treatment that can heal our dead, nutrient-starved soils.


Our love of Rudolf Steiner’s work continually inspires us to grow the endeavor; that more and more of the Earth may receive the enlivening effects of the compost preps.


We are also discovering through lots of good, hard work that economic life can be profitable in all realms, monetarily and soul/spiritually, through cultivating human relationships of cooperation through all the aspects of the economic process.  Though the urge to look out for oneself first and foremost is alive and well in modern life, we continually discover that when you look out for the “higher human” in all exchanges, real growth happens in a mutually harmonious way.


 Growing with and out of SeaCoast Compost is also a retail plant nursery, construction company, bakery and coffeeshop, and Flow-Form manufacturing.  These businesses work and breathe together aiming to realize a brotherhood experience in economic life.

Wynbrandt Farms is a micro-farm urban agriculture farm located in Los Angeles, CA.  Owner Steven Wynbrandt produces Biodynamic® certified compost in small batches, in addition to teaching workshops and raising produce for direct-sale to the local community and to restaurants. 

 

“It is my core belief that when compost is made as a high art, it is a profound product of alchemy that holds answers to some of the most critical issues humanity faces, from reversing climate change to restoring and elevating the health and vitality of soil, and thus, of humanity. Wynbrandt Farms is rooted in the awareness of the interconnectedness of all life on earth, and practices that restore and elevate the symbiotic, life-sustaining capacity of the living skin of the earth so that soil, plant, animal and human populations can truly thrive.”  -- Steven Wynbrandt

In Remembrance of

Chris Shepherd


by Dillon Miskiewicz

CEO of Cafe Altura

Image description

Chris Shepherd was a remarkable human being, but what made him truly special was the way he saw the world. He never viewed coffee as merely a product to be bought and sold. For Chris, agriculture was a living relationship between people, the land, and the communities that depend upon both. His conviction that farming should be environmentally sound, socially just, and spiritually meaningful was the foundation upon which Café Altura was built more than four decades ago.


Long before sustainability became a marketing term, Chris was advocating for farming practices that honored the health of the soil, respected the dignity of farmers, and recognized our responsibility to future generations. These beliefs naturally led him to the Biodynamic movement, where he found a community of people who shared his understanding that healthy farms, healthy ecosystems, and healthy communities are inseparable. Through Demeter and the broader Biodynamic community, Chris formed deep friendships, found inspiration, and strengthened his commitment to supporting agriculture that regenerates rather than depletes.


I was fortunate to experience that world through Chris. When I joined Café Altura, he took a chance on me and opened a door that changed the course of my life. Over the years, he shared his knowledge generously and entrusted me with increasing responsibility. He taught me lessons that cannot be learned from books—about integrity, perseverance, stewardship, and the importance of caring for people. More than a mentor, he was a teacher, a guide, and a friend. I will always be grateful for the opportunity he gave me and for everything he taught me along the way.


Today, Chris's son, Will Shepherd, and I share the responsibility of carrying forward the work that meant so much to him. For Will, Café Altura is far more than a business. He quite literally grew up alongside it. He witnessed firsthand the relationships his father built over decades with farmers, customers, colleagues, and members of the Biodynamic community. Many of the people who have been part of Café Altura's journey have been part of Will's life for as long as he can remember. The community that surrounds Café Altura, built on shared values, mutual respect, and genuine friendship, is an important part of his family's story. Together, Will and I view ourselves not as owners of Chris's legacy, but as its stewards, entrusted with preserving the principles, relationships, and sense of purpose that he worked so hard to cultivate.


Chris's legacy extends far beyond the company he founded. It lives on in the farms he supported, the relationships he cultivated, and the countless people whose lives were touched by his work and example. His belief that business can be a force for good remains as relevant today as it was when he began this journey.


As we reflect on Chris's life, there is no greater tribute we can offer than to continue the work he devoted himself to so faithfully. At Café Altura, we remain committed to the principles that guided him from the beginning: supporting Biodynamic and organic agriculture, building meaningful and equitable relationships throughout the supply chain, caring for the health of people and the planet, and conducting business with integrity and purpose. Though Chris is no longer with us, the values he championed and the community he helped nurture will continue to inspire and guide us for generations to come.


We are deeply grateful for Chris's life, his leadership, and his unwavering belief that agriculture can heal the land while bringing people together. His work continues in every farm stewarding the earth with care, every community strengthened through conscious agriculture, and every person inspired by his example.

Opportunity from the

Josephine Porter Institute (JPI)


JPI Merit Grant Program


The JPI Merit Grant was launched on January 6, 2026, offering biodynamic preparations free of charge to applicants from around the world.  Visit their website to learn more about this program:  Merit Grant: Biodynamics & Regenerative Agriculture

- Staff Corner -



Demetria Stephens

Certification Specialist

Visiting Churchtown Dairy with Jennie and Jean-David.

Highlights from the Josephine Porter Institute Biodynamic Farmer and Gardeners Forum on Zoom, June 2, 2026


Number 1: Pest problems have more remedies than you can buy from the store. Growers discussed strategies that included preparations used, understanding predators, and how to make peppers.

 

Number 2: The best test for preparation qualities is to use your basic senses. Tests based on chromotography have been explored by the Fellowship of the Preparation Makers and create a visualization of preparation qualities that requires interpretation. The number of practitioners of this testing method is increasing, and experience is needed to understand the results. Other methods include compost analysis by a third-party lab and observations made through a microscope. These testing methods are complimentary but are not a replacement for making preparations, working with them, and observing the results firsthand.

 

Number 3: Valerian spray (BD507) focus: it is alternatively used as a frost protection spray. Rainwater is the best water to use when making the valerian preparation, but when it's not available and you have fresh flower, you should make do with the water you have at hand. 

 

Number 4: The next meeting is planned to be July 7, 2026. Anyone interested in subscribing for meeting notices should email [email protected]

Research Focus

🌿The Effects of the Biodynamic Preparations on Crop Performance

🌿 Nettle Extract Application Response in Table Grapes


A 2019 paper that may be of interest to our readers looked at the effects of the Biodynamic preparations on crops, particularly root growth, in several studies carried out by the paper’s author in the 1980s and 90s but never published.   The research looked at the use of the horn manure preparation and also compound preparations – manure and nettle.   Comparisons of biodynamic, organic, and conventional crop management were made.   They found that, “preparations can increase soil carbon, root growth, and yield stability and that multiple applications of preparations are more likely to induce statistically significant yield increases.”  The paper discusses the implications related to carbon sequestration for this increase in root growth. Read the full paper here.   


In December 2025, a group of scientists delivered a paper about the use of plant-based biostimulants, in this case stinging nettle, on plant growth and performance.  The researchers applied stinging nettle extract at various concentrations to table grape foliage and measured the response.  The authors determined that “overall, the findings demonstrate that stinging nettle extract exhibits biostimulant potential in grapevine, with the 50–75% dose range representing the most suitable application interval for promoting growth and development.” The paper can be found here.
