Biodynamic Compost Preparations

The biodynamic preparations can be viewed as healing remedies for the Earth. It is painfully clear that our planet is in the need of our attentive care and the biodynamic preparations are one way for us to fulfill our role as healers through our agricultural activities. When working with the biodynamic preparations we are harnessing the life forces in a way that allows them to act as catalysts to enhance the health and balance of our farm. Read more.

Making and Buying the Preparations

You don't need to make your own preparations to get started. Ready-to-use biodynamic preparations can be purchased from professional preparation makers, including those listed below.

Regional Groups

Many regional biodynamic groups make the biodynamic preparations together as a seasonal community activity. Joining a regional group is a great way to learn how to make the preparations, and often finished preparations can be purchased from someone in the group.

Josephine Porter Institute (JPI)

JPI's mission is to heal the earth through production of quality biodynamic preparations, and to advance education and research in biodynamic methods. They are a source for purchasing the biodynamic preparations, an education center for all biodynamic practitioners as they begin to make their own preparations, and as a research venue focusing specifically on the biodynamic preparations.

Biodynamic Source

Biodynamic Source offers the expertise and efforts of BioSprays, a Biodynamic agricultural application service founded by Lloyd Nelson with Brook LeVan cofounder of Sustainable Settings, a 501 ©(3) corporation that was founded in 1997 that owns and operates the Demeter Certified 244-acres that make up the working ranch and Whole Systems Learning Center.

Earth Legacy Agriculture

Established by long-time biodynamic prep maker and JPI founder Hugh Courtney and his grandson Jeremiah Proctor, Earth Legacy Agriculture was formed to support biodynamic producers, whether long-standing or under transition, through education and consultation services. Courtney has been making biodynamic preparations on the farm in Virginia since 1976. ELA produces and distributes biodynamic preparations and microbial activators and hosts various educational workshops.


Fellowship of Preparation Makers

The mission of the Fellowship of Preparation Makers is to ensure that good quality biodynamic preparations are available now and into the future throughout North America. The Fellowship (previously called the Future of the Preparations) is an informal, vital, and growing group that has emerged in the cultural/spiritual sphere of biodynamic agriculture.

Report from the Section for Agriculture

The Biodynamic Preparations in Context: Individual Approaches to Preparation Work (link is external)

The Section for Agriculture commissioned, directed, and published this study on the biodynamic preparations (link is external). It is particularly directed towards the International Biodynamic Association (IBDA), Demeter International (DI) and the Circle of Representatives of the Section for Agriculture, and especially their member organizations and their individual members. This publication (link is external) contains 14 case studies with comprehensive and easily compared descriptions showing how a selected group of people from across the world work with the preparations in their own geographical and social contexts. 

"Only What Is Fruitful Is True"

Stewart Lundy of Perennial Roots Farm discusses assessing quality (link is external) of the preparations and the value of hands-on learning with Hugh Courtney of Earth Legacy Agriculture.
