Well, I guess I've ben practicing biodynamics and didn't even know it.
I tested the validity of planting/harvesting/weeding/etc by the sign of the moon and in so many ways it showed itself to be of value. Thus, I have gardened that way for decades. (A side note: I accidentally broke a branch off a plant recently and decided to root it rather than throw it away. Only problem it was the wrong time of the moon. I was shocked when after 2 weeks it appeared to be putting on new growth and looked great. Then 1 week later it turned to absolute mush. All the other plants/cuttings/seedlings around it are still doing fine, so it wasn't the conditions.)
As to the composted weeds and ground cow horn, I have a friend that swears since he started using weed tea on his yard it has never looked better than it does right now.
And why not cow horn? It's an obvious protein and who knows what else. Who knows what all it could be good for? I mean, corn meal is suppose to help keep weeds down...
And finally, in order to remove pests, you burn them and spread the ashes over the soil? I had a friend, now gone, that swore the best way to keep bugs away was leave the dead ones right where killed them in your yard. She claimed the other bugs could sense their remains and wouldn't go there. She had a beautiful yard.
