Biodynamic research is research into the Biodynamic method of agriculture. Motivated to improve Biodynamic agriculture and deepen the understanding of it, independent research facilities emerged decades ago e.g. in 1950, the Institute for Biodynamic Research in Germany (www.forschungsring.de) was founded. They were at the same time, the first research institutions of organic farming. In some European countries there are now institutions which deal partly or mainly with Biodynamic research (see attached list). The international contact for Biodynamic research programs is the Agricultural Section at the Goetheanum.
Biodynamic research covers all major areas of the agricultural sciences, where many issues of significance not only for Biodynamic agriculture, but also for organic farming in general are being studied e.g. soil fertility, food quality and plant breeding. In addition, there is research focus naturally on the Biodynamic preparations. Primarily, the classical scientific method of investigation is used.
Biodynamic agriculture is based on a broader understanding of the human being, plant, animal, earth and cosmos. It is therefore closely connected with the development of research methods that seek to understand human nature in a holistic way.
A hallmark of these research approaches is to give serious recognition to the holistic human being and how consciousness is accessed. This is associated with the appreciation of ones own senses. Knowledge will not result from a rapid integration of the facts into an existing paradigm (like materialism). An unbiased, i.e. model-free, consideration of phenomena will create the possibility to learn new things and unexpected facts about the particular object of study.
Goethe in his natural science investigations established this method. Rudolf Steiner developed the approach further, naming it accordingly ‘Goetheanism’. One of the resulting applications is the Goethean observation of plants – plants are seen in a time continuum allowing statements to be made about for instance harmony in their development (www.anthrobotanik.eu). The phenomenological observation of life leads to an appreciation of the manifestations of the life of plants, animals, etc. in their rhythms, transformations and relationships with nature and the cosmos. It provides guidance for a broader understanding of living things and their context.
Research on Biodynamic quality means studying maturity, aging, organ formation (e.g. seed, fruit, leaf) or light and shade effects since these are seen as being just as important for the evaluation of food as an analysis of their nutritive components.
Central to the indirect perception of such effects in foods are the so-called picture-forming methods such as copper chloride crystallization and paper chromatography. These are imaging techniques which use the sensitivity of certain metal salts to respond to the addition of small quantities of organic matter in solution by generating specific forms and colours. The two methods have been scientifically validated in recent years at the University of Kassel. (Webmaster: All of the following documents are in German.)
A number of scientific papers on the methods are available. Copper chloride crystallization and chromatography are used at the Forschungsring e.V. amongst other research stations in Germany for the development of quality in Biodynamic products.
The holistic understanding of humans also causes observations to be taken seriously, which can not be classified using the senses because they are of a soul-spiritual nature. Out of a training in observation of the self and the natural world, a method has emerged to detect forces that constitute the living and lead to their sensory perception. This so-called formative forces research initiated by D. Schmidt has become an element of Biodynamic research into quality in recent years.
Using it, the effects of food on the human body and life forces can be closely monitored and characterised.
Although Biodynamic research is based on high ideals, it is not unworldly; it is aimed at solving fundamental and current issues. Some examples are:
- Climate change is exposing our crops to increasing weather fluctuations. The greater root penetration proven to be found in Biodynamic farming offers a strategy to reduce the problem (see Raupp et al., 2006).
- What aspects of genetic interventions produce unintended effects on plants? An exact description of plant morphology over time proves that significant unintended effects not picked up by usual gene analysis evaluation are present.
Richter R, Damme J v, J Wirz 2011: Unintended phenotypic effects of single gene insertions in potatoes – assessing development dynamics and leaf morphology. Elemente der Naturwissenschaft 95, 9-24.)
- Which agricultural method leads to the largest content of high value nutritive components? In several studies Biodynamic farming has shown higher levels than conventional or organic farming. (See Heimler et al, 2011).
- Is the effect food has on man described completely by its constituent parts and taste? Food has an emotional component quite apart from the pleasure it provides. Using enhanced sensory testing these effects become scientifically measurable.Geier U, Hermann I, Mittag K, Buchecker K. 2012: First steps in the development of a psychological test on the effects of food on the mental well-being.

- In a field trial looking at three parameters (Fritz and Köpke, 2005), beans were tested under varying levels of light and manure and with varying horn silica application dates. The germination characteristics of the harvested seeds from the field trials were tested under uniform conditions. The germination percentage of the seedlings was increased by horn silica applications compared to the control in one of the three experimental years. The result had a high level of significance.Fritz, J.; KÖPKE, U.
