The following article first appeared in The Stinging Nettle, a publication of the North Central Region Biodynamic Group.

At the very end of the fifth lecture of the Agriculture course, in which Rudolf Steiner describes the compost preparations in great detail, he inserts an offhand comment: Before you make use of the manure thus prepared, pressout the flowers of valerian (officianalis). Dilute the extract very highly. . . . Add this diluted juice of the Valerian flower to the manure in very fine proportions. Then you will stimulate it to behave in the right way in relation to what we call the"phosphoric" substance. [Agriculture, tr. George Adams] He left it to the Experimental Circle and biodynamic practitioners over the next eighty years to figure out the best way to extract this juice, and a wide variety of methods have been developed. Douglas Elmquist of Community Homestead in Osceola, Wisconsin, has created a simple but elegant device that quickly and effectively presses the juice out of valerian flowers. The design for this press is based on that of a cheese press, and is presented below.
