Extension Falls for Fake Science

IMO, biodynamics is fake science, so I'm distressed the Extension website would host this post.  From the Demeter website:

The use of the preparations is a requirement of the Farm Standard. There are nine in all, made from herbs, mineral substances and animal manures, that are utilized in field sprays and compost inoculants applied in minute doses, much like homeopathic remedies are for humans.[emphasis added] Timely applications revitalize the soil and stimulate root growth, enhance the development of microorganisms and humus formation, and aid in photosynthetic activity.

 What are the preparations?  According to wikipedia:

• 502: Yarrow blossoms (Achillea millefolium) are stuffed into urinary bladders from Red Deer (Cervus elaphus), placed in the sun during summer, buried in earth during winter and retrieved in the spring.
• 503: Chamomile blossoms (Matricaria recutita) are stuffed into small intestines from cattle buried in humus-rich earth in the autumn and retrieved in the spring.
• 504: Stinging nettle (Urtica dioica) plants in full bloom are stuffed together underground surrounded on all sides by peat for a year.
• 505: Oak bark (Quercus robur) is chopped in small pieces, placed inside the skull of a domesticated animal, surrounded by peat and buried in earth in a place where lots of rain water runs past.
• 506: Dandelion flowers (Taraxacum officinale) is stuffed into the peritoneum of cattle and buried in earth during winter and retrieved in the spring.
• 507: Valerian flowers (Valeriana officinalis) are extracted into water.
• 508: Horsetail (Equisetum)

 I can grasp some logic in saying the farm should be self-sustaining; don't import anything. It's locavore ag carried to the nth degree.  But logically that means don't export anything, all excretion must occur on the farm.  As I say: stuff and nonsense.
