Biodynamic preparations

Biodynamic farming is largely based on farming practices that have been used for centuries, which are part of the farming tradition, many of which also belong to the organic method, e.g. crop rotations, intercropping between different plants, composting green.

However, there is prepare whose use is a particularity of the biodynamic method: concretely, there are 6 cumulative preparations and 2 spray preparations. These biodynamic preparations do not exist in nature, but are made synthetically from natural materials and using natural forces .

What are the preparations

Biodynamic preparations should be considered like drugs intended to treat the environment, in particular the soil. We could compare them with Homeopathic medicine , for very small doses of the substance suffice to reactivate the energies and direct the agricultural organism to health. For example, cornosa is distributed in doses of 2/3 grams per hectare.

What are biodynamic preparations

Biodynamic aerosol preparations:

  • Prep 500: Horn Manure made from cow dung.
  • Preparation 501: Cornosilicon quartz powder.

Biodynamic cumulative preparations:

  • Preparation 502: Yarrow.

  • Preparation 503: chamomile.
  • Preparation 504: Nettle.
  • Preparation 505: Oak bark.

  • Preparation 506: dandelion.
  • Preparation 507: valerian.


For the preparation of biodynamic preparations flowers and leaves of medicinal plants are used these substances are buried in animal containers such as sheaths, mesentery, cow horns, then they are buried in soil that must be alive and rich in humus.

The container and the soil are an integral part of the preparation process. Floor has the task of r receive the forces and transport them to preparation. The container It is combined with the herb officinal by means of common elements, for example, for oak bark, the skull of the cow is used as the container, both are very relevant for calcium, so calcium is the common element between plant and animal substances.

In addition to the procedure the period is also important in which the substances will be buried, some will remain underground for six months, others like nettle for a year: most of the preparations are buried in September and removed from the ground in April there are special days to do it, like Easter and San Miguel, 501 is buried around June.

Once the substance has completed its period in the soil, it is removed from the soil and is no longer recognizable: the biodynamic preparation has the appearance of a dark, moist colloidal mass, smelling of weeds.

Preservation of preparations

The substance obtained by the procedure we have seen has an effective duration of one year provided it is properly stored. Biodynamic preparations should be stored in enamelled copper, glass or terracotta containers . Copper seems to be the best vessel due to the inherent high heat. The containers of the different preparations must be stored in wooden boxes lined with 15 centimeters of peat on each side, so that they do not exhaust themselves quickly, taking into account their radiant action.

The Cornosilic is an exception being a mineral preparation: it is kept in a transparent glass container that is kept in the sun, its effectiveness lasts two years.

For good conservation, the preparations must be constant humidity and controlled temperature . They must be checked constantly, at least twice a month, and if necessary intervene to keep them moist, a condition favorable to life. Indeed, the preparations are not only homeopathic substances but are living matter they contain useful microbes that would die if there was no water.

How preparations work

When we go to distribute the biodynamic preparations, we are unfolding something alive, a substance rich in microorganisms. The action of these micro-organisms is an integral and indispensable part of the treatment. The preparation placed in the heap gives therapeutic abilities and makes the soil capable of balancing the chemical and physical elements, managing the natural forces of earth and light and fixing nitrogen properly. This is the ideal condition for a healthy and fertile environment, where plants can be grown with natural methods, preventing them from getting sick.
