Biodynamic agriculture

From Anthroposophy

Biodynamic agriculture is a term coined after Rudolf Steiner's eight-lecture agriculture course (GA327) in June 1924, and furthered by Ehrenfried Pfeiffer (1899-1961). Commentaries to the course are available eg from Scharff and Nastati (see references).

Biodynamic agriculture has developed into a worldwide movements in over 40 countries.

It includes two main practical aspects:

  1. - to make soul and plant life more receptive or responsive to cosmic influences, by using field and compost preparations (as directed by Steiner)
  2. - to access appropriate cosmic timings for production of different crops making use of a biodynamic calendar.

The use of the so-called biodynamic calendar is a development from after Steiner's time, it was developed by Maria Thun (1922-2012) but has been the subject of debate on the basis of empirical research, see the work of Hartmut Spiess, see references below for both.

Biodynamic preparations

The biodynamic preparations are really processes to create materials with a soil activating vitalizing effect. There are seven as originally conceived by Rudolf Steiner:

  • the field sprays, referenced by numbers 500 and 501
    • 500: horn manure
    • 501: horn silica
  • the compost preparations, referenced by numbers 501 to 507
    • 502: yarrow - achillea millefolium
    • 503: chamomille - matricaria recutita
    • 504: stinging nettle - urtica dioica
    • 505: oak bark - quercus robur or Q.petraea
    • 506: dandelion - taraxacum officinale
    • 507: valerian - valeriana officinalis

The preparation processes make use of cosmic influences by storing the preparations in the soil for a year, some of them stored in animal organs or horns (see table below)

After research showed the efficacy of these original preparations, other people have developed and experimented with preparations (eg Hugo Erbe, Glen Atkinson, and others)


Although a huge amount of information is available around the worldwide biodynamic agriculture movement, and especially all is practical aspects, its spiritual scientific workings are not always clearly explained. For this one needs a study and appreciation of three aspects:

  • the work of elementals in the process
  • the process of transmutation
  • the study of the planetary and zodiacal influences

See Lievegoed (1951) for an explanatory discussion of the preparations:



Demeter Biodynamic Certification, established in 1928 as the first ecological label for organically produced foods, is used in over 50 countries to verify that biodynamic products meet international standards in production and processing. It is issued by Demeter International, a certification organization for biodynamic agriculture. Its name is a reference to Demeter, the Greek goddess of grain and fertility.
