The origins of Biodynamic preparations for soil were researched and published by Dr Rudolf Steiner in 1924. This is not to say that Biodynamic preparations and methods have not been in use for many thousands of years – but were perhaps known or classified as something other than Biodynamic. The methods used are designed to create a better fertilising process in the soil.
In Australia, these Biodynamic processes have been studied in repairing and improving upon soil issues – something that has plagued Australian primary producers for years.
“A healthy, well-structured soil, rich in humus and high in biological activity is a prerequisite for any sustainable agricultural system.” - http://biodynamics.net.au/
Biodynamic agriculture is similar in approach to organic approaches and processes in that it uses natural methods and products – specifically manure and other various compost to improve soil condition instead of artificial chemicals.
Herbal and mineral additives in pest sprays are commonplace in Biodynamic processes, as is the use of an astronomical system of planting and harvesting.
“A 2009/2011 review found that Biodynamically cultivated fields achieve lower absolute yields but better energy efficiency of production; impact the environment positively, including increased biodiversity.” – http://en.wikipedia.org/wiki/Biodynamic_agriculture
Wherever possible, the Biodynamic farmer seeks to use sustainable crops that will fit in with the climate of the local area – often crops or plant life that is indigenous to the area.
