A brief description of biodynamic agriculture
A healthy, well-structured soil rich in humus and high in biological activity is a prerequisite for any sustainable agricultural system.
Decades of experience with the Biodynamic (BD) method on farms throughout the world have shown that these soil qualities can be promoted, and degradation reversed by the correct application of BD techniques.
Mixed farms practicing the Biodynamic method have been in existence for over 65 years with none showing any evidence of loss of fertility or productivity.
Biodynamic practitioners seek to understand and work with the life processes as well as enhance their understanding of the mineral processes used in conventional agriculture. Healthy soil is a prime basis for healthy plants, animals and people.
BD farming practices are of an organic nature, not relying on bringing artificial fertilizers on to the farm, although some organic or natural mineral fertilizer may be necessary during the establishment phase.
On Biodynamic farms we seek instead to enhance the soil’s structure and nutrient cycles as well as plant growth and development with the use of specific Preparations which are made from farm-sourced materials.
These are Biodynamic Preparations numbered 500 to 507 used in conjunction with established agricultural practices such as composting and making manure, crop and pasture rotations, tree planting, the integrated use of livestock, use of rock powders, etc. As the name suggests, these Preparations are designed to work directly with the dynamic biological processes and cycles which are the basis of soil fertility.
Pest and disease control is generally managed by developing the farm as a total organism. However, BD practitioners may make use of specific products for weed and pest control, which they make from the weeds and pests themselves.
Weeds and pests are very useful indicators of imbalances in soil, plants and animals; and the aim in the Biodynamic method is to use such indicators in a positive way.
The Biodynamic Preparations were developed out of indications by Dr. Rudolf Steiner in 1924. They are not fertilizers themselves but greatly assist the natural digestive and enzymatic processes of the soil microorganisms. As such they only need to be used in very small amounts.
Horn Manure Preparation (500) is used to enliven the soil, increasing the micro flora and availability of nutrients and trace elements. Through it the root growth, in particular, is strengthened in a balanced way, especially the fine root hairs develops humus formation, soil structure and water holding capacity.
Horn Silica Preparation (501) enhances the light and warmth assimilation of the plant, leading to better fruit and seed development with improved flavor, aroma, color and nutritional quality.
Compost Preparations (502 to 507), known collectively as the compost preparations, help the dynamic cycles of the macro- and micro-nutrients, via biological processes in the soil and in material breakdown.
