Rudolf Steiner, whose agricultural lectures in 1924 gave birth to the biodynamic movement was a scientist as well as a philosopher and spiritualist. He emphasized that farmers and gardeners should conduct detailed experiments to test his far-seeing insights for themselves, and established an initial research group, which grew to over 800 members worldwide.
This has resulted in over 90 years of ongoing practical and theoretical research, which continues today. It includes, for example, long term comparisons between biodynamic, organic and conventional farming systems, the efficacy of the biodynamic preparations, research into food quality, as well as developing new sensitive picture forming methods for measuring the inner quality of plants , composts and soils. More recently research has concentrated on biodynamic methods in the production of high quality wines, sustainability, and carbon sequestration.

There are several dedicated biodynamic research institutes in various parts of the world. These include:
Section for Agriculture at the Goetheanum (CH), Switzerland
Research Institute of Organic Agriculture (FiBl), Switzerland
