On Biodynamic farms we seek to enhance the soil’s structure and nutrient cycles as well as plant growth and development, with the use of specific farm-sourced materials known as ‘preparations’. These Biodynamic Preparations are used in conjunction with established agricultural practices such as composting and manuring, crop and pasture rotations, tree planting and integrated use of livestock. The preparations are designed to work in line with the natural biological processes and cycles, which are the very essence of soil fertility. They were developed based on indications given by Dr Rudolf Steiner in 1924. They are not fertilizers in themselves but greatly assist the fertilizing process. As such they only need to be used in very small quantities.
