Alan Chadwick's image of fertility as a marriage of the elements brings soil, water, warmth, light, and living matter into one picture. The essay also evokes a meeting of Heaven and Earth from which plants arise. Fertility is a living relationship that growers tend, not one isolated input.
On the farm, gardeners care for that relationship in practical ways: water dry soil, add organic matter where it is needed, provide shade when sunlight is intense, and observe how plants respond. These acts work with the place and help build conditions for abundant growth.
Biodynamic preparations join sound farm care as enlivening additions. Biodynamics supplements practices that already support the soil and plants. Useful tools and technology can also serve a living farm when growers use them with care for soil, crops, and long-term fertility.
The key to biodynamics may be found in this: “The proof that we are regenerated,” as Saint-Martin said, “is that we regenerate everything around us.”
