In the early 1920s, a group of farmers approached Rudolf Steiner with concerns around soil depletion and the weakening of seed strains. As a result Rudolf Steiner gave 8 lectures in Poland in 1924: the biodynamic movement was born. Biodynamic agriculture recognizes the farm as a living organism, it works in close harmony with the soil, garden, animals, and earthly and cosmic cycles. By adding biodynamic preparations, soil life and fertility is improved, humus is built up and the nutrition and taste of the food increases. This nourishes, vitalises and helps to develop mankind.
