Sepp Braun has been an ecological farmer since 1984. At his farm near Freising he is practising ecological agriculture and also biological stock farming. For him and his wife it is more than just sustainable agriculture. Ecological agriculture is for them an answer to the question of climate change. While on conventional fields there are an average of 16 earthworms per square metre, on Sepp Braun’s fields there bustle about 25fold the quantity. It goes without saying that he respects the living conditions of these busy helpers.
