In early November last year, David Kinch and Cynthia Sandberg mixed their first biodynamic preparation of cow manure packed in cow horns, commonly called preparation #500 by biodynamic farmers, and buried them in the ground for six months, as prescribed by biodynamic farming principles established by Rudolf Steiner in 1924. Soon they will unearth the horns and mix the contents with water to make a liquid, which will be applied to the soil to stimulate root growth and humus formation, among many of the benefits of the #500 preparation.
Now that spring is here, David and Cynthia will undertake a process similar to making preparation #500. Once again they will bury cow horns, but they will pack the horns with ground quartz (silica) mixed with pond water or rainwater. After being buried in the ground for six months, the cow horns are retrieved and a liquid preparation is made to spray on the plant foliage in order to stimulate and regulate growth. This preparation is called #501, and it also influences the color, aroma, and flavor of the crop.
Summer vegetables are transplanted from the hoophouse to the outdoor garden.
