A companion to ‘The Secret Life of Plants’, this book by the same authors tells the story of the innovative, non-traditional, often surprising things that certain scientists, mystics, farmers are doing to prevent the slow degradation of the soil, to revitalize depleted soils and to reverse thereby the degradation of agriculture that must surely come if we allow our soils to die as has already happened in many places where excessive chemicals and fertilizers have ruined this most basic natural element of the planet.
