The Challenge of Biodynamics
By Brenda Frick, Ph.D.
Biodynamic farming challenges scientists and farmers alike. Scientifically
credible studies indicate that biodynamic systems have merit in terms
of soil quality, ecological impact, and economics, relative to comparable
conventional systems. Yet biodynamic understandings are in a different
realm than those of traditional scientists.
Biodynamic farming began with a series of lectures by Rudolf Steiner in
the 1920's. His teachings include both philosophical and practical aspects.
Neither has been become mainstream, but there are biodynamic farmers and
farm associations throughout Europe and around the world.
Biodynamic is a word that combines both biological and dynamic. The biological
component includes many of the principles of organic agriculture: a focus
on soil, including biodiversity and rotations for fertility and to keep
"pests" in balance, nonuse of synthetic chemicals (and more
recently nonuse of genetically engineered organisms). Steiner's "spiritual
science" adds the dynamic component and considers the role of ethereal
and cosmic forces on the individuality of the farm.
Steiner understood the farm as a living entity and the farmer through
his or her toil, intent and conscious feeling, as a motivating, even healing
part of that being. Some of Steiner's teachings resonate with accepted
scientific concepts, such as the "agroecosystem", while others,
particularly those involving planetary alignment and cosmic beings are
from a different way of understanding.
In practice, biodynamics differs from most organic farming in the use
of 9 preparations applied to the soil, the plants or to manure composts.
Typically, biodynamic farms include cattle; many are dairy and vegetable
operations. Manure is an important aspect of fertility and of the biodynamic
preparations. The first two biodynamic preparations are aged in a cow's
horn - manure fermented in the horn over winter, and applied to the soil
in spring, or silica fermented in the horn over summer and applied to
the crop plants. A further 6 preparations are made from yarrow, chamomile,
dandelion or valerian flowers; stinging nettle; or oak bark. These are
applied to the compost pile. A preparation of horsetail is applied to
plants for disease control.
Biodynamic preparations are made in a very precise way, diluted to extremely
low concentrations, and activated or energized with particular forms of
stirring. Recipes, products and directions for their use make the technologies
readily available.
Steiner's teachings also include an entire philosophical framework - anthroposophy.
These holistic teachings are linked to alternative medical treatments
such as homeopathy and eurhythmy and to alternative education as embodied
in the Waldorf schools. They call for an inner transformation that is
hard for people outside the transformation to fully understand. In many
ways, anthroposophy is a different paradigm, or way of understanding,
than the science that we value so highly in our society. Science values
physical, material explanations, while anthroposophy considers that materialism
gets in the way of spirituality.
Some biodynamic practitioners are well versed in anthroposophy, and consider
this an essential attitude for healing the earth and moving the farm "individuality"
to health. Some are less convinced by the philosophy, but follow the techniques
none-the-less. These people feel that many of Steiner's broad themes are
reasonable, even while they question the details of his explanations.
In New Zealand, researchers studied biodynamic and comparable conventional
farms. They found that "biodynamic farms proved in most enterprises
to have soils of higher biological and physical quality: significantly
greater organic matter content and microbial activity, more earthworms,
better soil structure, lower bulk density, easier penetrability, and thicker
topsoil.
the biodynamic farms were just as often financially viable
as their neighboring conventional farms."1
In Switzerland, researchers compared biodynamic and organic systems to
two types of conventional systems. They also found greater soil fertility
and biodiversity on the biodynamic and organic plots than they found on
conventional plots. The biodynamic system had greater microbial biomass,
diversity and activity, than the organic system, which had greater microbial
values than the conventional system. The authors suggested that this microbial
activity would improve phosphorus uptake, nitrogen use and plant productivity.2
These studies clearly show that biodynamic systems can have soil benefits.
Whether biodynamic preparations provide essential nutrients that foster
the growth of beneficial microbes, or if they help the spirituality of
the farm connect with cosmic forces, the techniques appears well worth
further study. For scientists, perhaps the challenge lies in not rejecting
techniques because they are explained in a way that does not fit our understanding.
The Organic Connections conference in Saskatoon, Nov 14-16
will include a workshop on biodynamic farming where these ideas will be
discussed further.
