Secrets of the Soil tells the fascinating story of the innovative, nontraditional, often surprising things that certain scientists, farmers, and mystics are doing to save our planet from self-destruction - such as using the techniques of Rudolf Steiner's biodynamic agriculture with its reliance on ethereal forces from the planets, Dan Carlson's growth stimulating Sonic Bloom, and rock dust fertilizer to revitalize depleted soils; or gardening with the help of truly amazing new technologies to reverse serious agricultural problems.
