Biodynamic Preparations

BC - Biodynamic Compound Spray Preparation (Adapted from Maria Thun's Barrel Compost Recipe)

Barrel Compost based on Maria Thun’s recipe developed to counter uptake of radio-active fallout. Contains BD #502-507, basalt and eggshells. Useful when access to BD compost is limited and when plants are under stress. Should not be regarded as a long-term substitute for properly made BD compost.

How to use BC Biodynamic Compound Spray
Stir vigorously for twenty minutes. Spray to soil immediately. Best results are achieved when used periodically throughout the season. One unit is enough for up to one acre when stirred properly.
