"The six compost preparations are made from specific herbs: yarrow flowers, chamomile blossoms, the whole areal portion of the stinging nettle while in flower, oak bark, dandelion blossoms and valerian flowers. Four of these six preparations are enveloped in sheaths of animal organs. All are made with a sensitivity to the rhythms of the sun and zodiac. All but one are buried in the ground for a specified period of time. When the preparations are finished, they have the appearance of well-ripened compost, with the exception of the valerian preparation, which is in a liquid form. "

Then they make 6 holes in a compost pile that has been piled up all at once (i.e. have all the ingredients ready and build the pile). Put one of the "preparations" in each hole. Close the holes and spray the whole pile with the valerian infusion. Supposedly helps the compost pile work more steadily and give a better finished product. "The effect of the compost preparations continues when the compost is spread on the soil, making the soil more sensitive to cosmic rhythms (especially those of the planets and the moon). They also work in a myriad of ways to help balance life processes, especially in the way that fertility is made available to the plants." From the same article as above, where there is more info.
Here's a relatively recent thread we had about biodynamics
https://www.helpfulgardener.com/forum/vi ... 11&t=58310
in it I said "So yes the basics of biodynamics are very much what I do with very diversified plantings, closed loop composting, no synthetics. But once they get out into that "subtle influences of the wider cosmos" stuff, it goes all woo-woo and loses me. " same applies to above cosmic rhythms etc. Mumbo-jumbo to me.
How did you get interested in biodynamic composting?
