Biodynamic Horn Silica Preparation (BD 501F) Feldspar-Based (BD Spray Preparation)

Hugh Courtney postulates that while horn silica 501 made from quartz rock crystal may be most effective for those on mainly heavy clay soils, those on sandier soils might benefit from using a form of horn silica 501 with a stronger relationship to the lime end of the lime/silica polarity. In this case orthoclase or feldspar with their constituents of calcium or related elements – feldspar being principally aluminum silicates of potassium, sodium and calcium – would be used. – Monty Waldin At a Glance: What it does:Enhances photosynthesis and strengthens plant structure.
