In Biodynamics we seek to repair and improve soil structure and nutrient cycles resulting in enhanced plant growth and development, with the use of specific Preparations that are made from farm-sourced materials.
These are the biodynamic preparations numbered 500 to 507 used in conjunction with established agricultural practices such as composting and manuring, crop and pasture rotations, tree planting, the integrated use of livestock, 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, biodynamic 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; the aim in the biodynamic practitioner’s method is to use such indicators in a positive way.
The biodynamic preparations were developed out of indications given by Dr Rudolf Steiner in 1924. They are not fertilisers themselves but greatly assist the fertilising process. As such they only need to be used in very small quantities.
Biodynamic practices are of an organic nature, not relying on bringing artificial fertilisers on to the farm, although some organic or natural mineral fertiliser may be necessary during the establishment phase.
