Biodynamic agricultural theory was first developed in 1924 by Austrian thinker Rudolf Steiner.
"Biodynamic farming involves managing a farm utilizing the principles of a living organism.
In day-to-day practice the goal is to create a farm system that is minimally dependant on imported materials, and instead meets its needs from the living dynamics of the farm itself. It is the biodiversity of the farm, organized so that the waste of one part of the farm becomes the energy for another, that results in an increase in the farm’s capacity for self-renewal and ultimately makes the farm sustainable." - Demeter Association
