Quality assurance for the production of the biodynamic preparations

Dr. U. J. König

The biodynamic compost and spray preparations (=“preparations”) created out of natural and
organic substances are used in minute doses to enhance soil life, plant growth and quality and
animal health. They act as a kind of “bio regulator”, forcing the self regulation of biological
systems, e.g. the farm’s whole biological cycle (1).

They are essential to biodynamic agriculture and their use is a recognised requirement of the
Demeter Standards.

The production of preparations takes place on the farm. The method of production involves
taking certain plant materials (e.g. chamomile flowers, grated oak bark and dandelion
flowers), cow manure or quartz meal, placing them in selected animal organ parts and
fermenting them in the soil for certain period of time, usually half a year. After the
preparation has been dug out remaining residues of animal organs are disposed of according
to the current regulatory requirements.
