Vanderbilt Minerals VANSIL W-10 Wollastonite
Natural Calcium Silicate Fertilizer, OMRI Organic Approved
Use as an alternative to limestone and to provide Plant Available Silicon and Calcium in your soilless potting mixes.
Wollastonite, a natural calcium silicate mineral, is unique among soil amendments as a source of silicon and carbon-neutral calcium. VANSIL wollastonite is sourced from a Vanderbilt Minerals deposit and processing facility in northern New York state. It is the only OMRI certified wollastonite mined and milled in the United States.
For best results, apply wollastonite according to soil test results and agronomic recommendations. Application rates will vary according to plant requirements and soil conditions. Consider calcium and magnesium requirements in addition to silicon supplementation when using this product as part of a balanced fertility program
