The animal organs are chosen for the unique properties they possess as a result of their former function within the animal organism and serve as catalysts for bringing about the desired fermentation. For example, chamomile flowers are used medicinally to treat disturbances of the digestive tract. When making this particular compost preparation a section of bovine intestine (part of the animal’s digestive tract) is used as a catalyst in the fermentation. A clear affinity between chamomile flowers and this organ becomes apparent.
There is also a chart detailing the quantities of “organ material” needed per acre. These include skulls, bladders and lengths of intestines.
As Jim pointed out before, the quantities are homeopathic. So even when gold is used as in the three kings preparation (only to be used on January 6th) it’s only a 15g quantity, so it is a bargain at £22.80.
You can buy a bag of 10 cow horns or just a single one, presumably for the lone biodynamic gardener. You can buy the horn manure at £4.20 for half a unit or £4.80 for a whole unit.
Why do I mention this? Because there are still people in Stroud who don’t believe the details of how biodynamics is carried out. Surely pictures of little bags of manure and a chart showing how many skulls to use per 300 hectares, and how many centimetres of “bovine mesentery” per 100 hectares on this official website are convincing enough?
Rudolf Steiner’s instructions are being followed closely by biodynamics enthusiasts. Organic methods are not good enough for them. They need the skulls and the bladders and the intestines, not to mention the astrology and the cosmic forces.
