Biodynamic preparations

What are the various preparations, how are they used, and why?

The horn silica preparation (501) is very finely ground crystal quartz. It is dynamised in water for an hour before spraying, and has the effect of giving harmony to the plant by promoting leaf, flower and fruit development.

The horn manure preparation (500) works on plant root development, plant form and its vitality, promotes plant growth, the soil micro-life which is active in the humus fraction and the Ego component of our cultivated plants. The one hour stirring rounds out the 500 making process and it becomes active as it is spread on the land.

The compost preparations (502-507) have the task of promoting humus development by drawing in ordering forces from the cosmos. They also promote soil life which is responsible for breaking down all organic materials, and in connection with the mineral clay substances build up the clay-humus complex in the soil. They do this by combining the elements of dead organic materials, soil, soil life and water into vital humus. The cow pat pit (cow pat compost) shows their capacities clearly in its final form.

How to produce and use the Biodynamic preparations?

Biodynamic Preparations - Good practice manual

We are happy to present as our first publication by the Biodynamic Federation, a good practice manual for the production and use of the Biodynamic Preparations.

Anne and Rolf Bucher, experienced biodynamic gardeners and active as biodynamic advisors for farming communities in Asia and Africa, have described all the steps in making preparations, from cultivation and harvesting of the plants through the processes for each and ending with the storage and the use of the preparations themselves. It includes a chapter on CPP or fladen.

The manual is meant as a practical guide for beginners, to support active engagement with the preparations and is suitable for introduction courses.

Where do you get the Biodynamic preparations from?

Most Demeter farmers and gardeners produce the preparations either themselves or together with a Biodynamic advisor. However in the case of shortages, the following addresses are able to help:
