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 of Preparation Makers (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. The Fellowship began its work with a conference in Copake, New York in 2002, and has held annual conferences in various locations around North America for the last sixteen years. These conferences have focused on the intensive study and discussion of the biodynamic preparations and have strengthened the preparation making community.

A guiding principle for the group’s work derives from Rudolf Steiner’s suggestion that we attempt to 1) discern what of a positive nature is already arising and developing in the world, and then 2) seek to intelligently support its organic developmental process, the way a farmer or gardener supports a living plant. It is in this spirit that the FOPM seeks to fulfill its mission.

Biodynamic Preparation Makers Interview Project

The mission of the Biodynamic Preparation Makers Interview Project is to chronicle the knowledge and practices of a representative spectrum of experienced preparation makers in North America.

The project’s vision is that it create an overview of preparation making in North America that will serve both as a historical record and as means of sharing instructive practices with current and prospective preparation makers.  It is envisioned that insights shared during these interviews will advance preparation making and spur innovation, collaboration, and dialogue.

The making of biodynamic preparations is foundational to biodynamic agriculture. Without dedicated preparation makers, biodynamic farming practices would not continue. The Fellowship of Preparation Makers feels that the knowledge, experience, and wisdom of preparation makers in North America has never been adequately recorded for present and future biodynamic practitioners.

Current Supporting Organizations and Individuals include:

2018 was a busy year for the Interview Project Committee! They conducted six interviews with eight committed, long-time preparation makers from all parts of the continent. Each of these interviews produced:

  • A written set of responses to pre-interview questions, that gather background information for each interviewee and the group with whom she or he makes preparations;
  • A recording of an oral interview guided by another set of deeper questions, that explore the thinking, feeling, and practices of each interviewee;
  • A written transcript of each of the six interviews that will be summarized, and the summaries posted on this page in the next few months.

The committee has at least four more interviews scheduled for the first part of 2019 and plans to conduct ten total for the year.

Preparation Evaluation Committee

How can one know if the biodynamic preparations they have made or obtained are of good quality and will be effective? This is a central question motivating the work of the Preparation Evaluation Committee. The committee is exploring what methods have been used or could be applied in the future to understand and assess the quality of biodynamic preparations, ideally supporting practitioners to make their own assessments. 
The mission of the Preparation Evaluation Committee is to identify ways to assess the quality of biodynamic preparations through their characteristics and effectiveness, considering observations of both physical substances and unseen forces.
To learn more about or participate in the committee's work, please check this page for updates or contact Brian Wickert (facilitator) at 608-606-1275

The Chroma Study Group

The Chroma Study Group is open to anyone who is interested in making Pfeiffer circular chromatograms for the first time and needs to source supplies—and those who have made chromatograms and would like to share their understanding of the interpretation of chromatograms of soil, compost and preps.

Currently, we are looking at the quality characteristics of different samples of BD 500 that might possibly indicate the unique signature of the farm or garden where the horns were buried in different regions of the US and Canada.

We have interesting conference calls on the second Tuesday evening of each month. For more information, contact Dewane Morgan at 218-366-1296 or email
