part 2: what is biodynamics?

It is helpful to think of biodynamics not primarily as an agricultural system, but rather as an altered philosophy or worldview that then impacts on the practice of agriculture in various ways. In other words, to farm biodynamically, first you have to think biodynamically.  

It has its roots in a series of lectures delivered by Austrian philosopher–scientist Rudolf Steiner in 1924. Steiner’s life mission was to bridge the gap between the material and spiritual worlds through the philosophical method. To this end, he created the ‘spiritual science’ of anthroposophy, which he used as the basis of the Waldorf school system that persists to this day.

It was only quite late on in Steiner’s life that he turned to agriculture: his eight lectures, entitled Spiritual Foundations for the Renewal of Agriculture, were delivered just a year before his death, but they remain as the foundation of biodynamic farming. Modern biodynamic practice is built on top of Steiner-inspired theories, but it is important to emphasize that there are a number of growers who practice biodynamics but who would distance themselves from Steiner’s beliefs and teachings. 

Key to biodynamics is considering the farm in its entirety as a living system. To this end, biodynamic farms are supposed to be closed, self-sustaining systems. Biodynamics also sees the farm in the context of the wider pattern of lunar and cosmic rhythms. In this holistic view, the soil is seen not simply as a substrate for plant growth, but as an organism in its own right. The idea of using synthetic fertilizers or pesticides is thus an anathema to biodynamic practitioners. Instead, they use a series of special preparations (see Table) to enhance the life of the soil, which are applied at appropriate times in keeping with the rhythms of nature. And disease is seen not as a problem to be tackled head-on, but rather as a symptom of a deeper malaise within the farm ‘organism’: correct the problem in the system and the disease will right itself.

The different biodynamic preparations

Preparation

Contents

Mode of application

500

Cow manure fermented in a cow horn, which is then buried and over-winters in the soil

Sprayed on the soil typically at a rate of 60 g per hectare in 34 litres of water.

501

Ground quartz (silica) mixed with rain water and packed in a cow’s horn, buried in spring and then dug up in autumn

Sprayed on the crop plants

502

Flower heads of yarrow fermented in a stag’s bladder

Applied to compost along with preparations 503-507. Together these control the breakdown of the manures and compost, helping to make trace elements more available to the plant

503

Flower heads of camomile fermented in the soil

Applied to compost

504

Stinging nettle tea

Applied to compost. Nettle tea is also sometimes sprayed on weak or low vigour vines

505

Oak bark fermented in the skull of a domestic animal

Applied to compost

506

Flower heads of dandelion fermented in cow mesentery

Applied to compost

507

Juice from valerian flowers

Applied to compost

508

Tea prepared from horsetail plant (Equisetum)

Used as a spray to counter fungal diseases

Note: All these preparations are diluted and then activated or energized by a special stirring process known as ‘dynamization’. 

Biodynamics is in effect a supercharged system of organic farming. Where biodynamics differs significantly in practice from organics is in the use of these special preparations and the timing of their application—in other ways the techniques employed are quite similar. 

As I’ve talked to various biodynamic winegrowers from around the world, one thing has become clear. While they tend to agree on the big details, each has their developed biodynamics to suit their own particular situation. Winegrowers drawn to this philosophy tend to be inventive types, always experimenting and refining their practices to see what works best. As a result, there are many different flavours and variations around this common theme, and it’s hard to define biodynamics in any sort of rigid way.

In later parts of this series we’ll explore in greater depth exactly what applying biodynamics to a wine estate would involve, and take a look at a biodynamic property in operation.
