Horn pebbles
As a horn silica (also preparation 501 ) a preparation is in the biodynamic agriculture designated.
Recipe
A rock crystal ground into powder is put into a cow horn and buried in the ground over the summer. Then 2–4 g of the preparation in a barrel ( preferably: wood, non-electrochemically pickled stainless steel, copper and clay vessels) are stirred with water for one hour and, after the onset of plant growth, sprayed over the land (10–50 liters / ha ) . This should correspond to the effect of the warm sunshine and increase the aroma and shelf life of the food. The effect of this preparation is explained from the point of view of the doctrine of anthroposophy , which was founded by Rudolf Steiner around 1924.
From a scientific point of view, the effect cannot be understood.
