Horn Silica is a substance based on quartz powder that is used as a method of plant treatment in biodynamic agriculture. Pot experiments with Phaseolus vulgaris compared Horn Silica application, K-Mg and N fertilizers, and extracts of different plant species. Results from Horn Silica and Digitalis purpurea application, averaged over 6 soils from conventional and organic fields, are presented. It is suggested that Horn Silica combined with plant extracts can be useful in soils converted to biodynamic cultivation.
