All about biodynamic farming and gardening which some people regard as organics plus. It contains some very useful tips and how to make the preparations which activate the microbes in the soil. I saw One Cow One Planet documentary and wanted to read a bit more about it. I am not versed in all Rudolf Steiner's theories though so some of the references are lost on me. Cultivating by the moon however is something I've recently embraced. If the preparations were more readily available to the home gardener (who does not have access to cows) it would be well to heal some of our terrible soils ruined by earthworks and development.
