With these talks, Steiner created and launched ?biodynamic? farming?a form of agriculture that has come to be regarded as the best organically produced food. However, the agriculture Steiner speaks of here is much more than organic?it involves working with the cosmos, with the earth, and with spiritual beings. To facilitate this, Steiner prescribes specific ?preparations? for the soil, as well as other distinct methods born from his profound understanding of the material and spiritual worlds. He presents a comprehensive picture of the complex dynamic relationships at work in nature and gives basic indications of the practical measures needed to bring them into full play.
