Collect the best cow manure you can, fill horns, and bury over winter in a rich place in the garden to make your own horn manure. One horn makes approximately enough 500 horn manure for three (3) acres.
Conversely, you can get horns, crush quartz to a fine flour (wear a mask!), mix with water to form a white paste, and fill the horn. Bury the horn over summer. This makes enough 501 horn silica for many acres (1 tsp per acre).
Our used horns have been used to make repeated successful batches of 500 horn manure and 501 horn silica.
These used horns are seasoned with the "mother culture" of biodynamics and have a stronger tendency to transform into healthy horn manure. By Steiner's indications, horns are useful at least for four (4) years, if not a few more (if "recharged" in proximity to cows in a barn). Some biodynamic practitioners reuse horns until they disintegrate and claim that used horns are significantly better than new horns. In our experience, new horns often take an initial season to "acclimate" to the biodynamic process, and after that more eagerly produce the horn manure we are seeking. We offer them to you at a significant discount, and encourage you to practice making your own preparations on your own property.
