Biodynamic farming
At the beginning of the '20s some farmers noticed that the land was losing its fertility and the products were less vital. They asked for advices to a scientist of those times, Dr. Rudolf Steiner, who, in 1924, gave eight lectures called agriculture course where he showed some methods to solve problems related to agriculture. Basically, biodynamic considers the farm as an organism on its own: its inhabitants are both independent and connected one another by relationships that allow mutual survival. Plants, animals, the farmer himself and their wastes contribute to fertilize, nourish and keep healthy the whole ecosystem.
In order to do that, the method has some instruments, such as: crop rotations, biodynamic preparations, compost, quality manure, lunar and planetary calendars, thus eliminating chemical fertilizers.
This way the fertility of the land is protected, so are the plants that grow naturally producing high quality food, and the whole ecosystem lives perfectly balanced.
Such method has consequences on the social system: the community that marries such lifestyle grounds its existence on the same principles as the biodynamic.
