Horn silica is an essential preparation to biodynamic agriculture. It is made by a long maturation of silica powder in a cow horn. A small quantity, dynamised in water, is then spread directly on the plants as a thin mist. This preparation is ideally used in springtime, as the plant approaches the peak of its vigour, and in the summer, as fructification begins. Applied early in the morning, after sunrise, and from a copper recipient, it regulates vegetative vigour, strengthens against illnesses, fortifies and softens the plant. Horn silica improves nutritive value, and help aromas reveal their full potential.
