Is a method of ecological agriculture based in the theories of Rudolf Steiner, founder of anthroposophy. This type of agriculture considers farms/cellars as complex organisms, emphasizing the interrelation between soils, plants and animals, treating the whole as a single system, avoiding as far as possible external interventions and taking into account the loss of nutrients due to the output of crops and other products outside the farm. As in other forms of organic farming, the use of fertilizers, pesticides and industrial herbicides is avoided. Biodynamic agriculture differs from other types of organic farming in the use of vegetable and mineral preparations as additives for compost and aerosols for the land, as well as in the follow-up of a sowing calendar based on the lunar movement and the stars.
