Wollastonite is a natural calcium silicate mineral and is unique among soil amendments as a source of silicon and carbon-neutral calcium. VANSIL wollastonite is sourced domestically and is the only OMRI listed wollastinite produced in the United States. VANSIL wollastonite is not contacted by chemical treatments of any kind. Because it is milled natural ore, elemental analysis can show natural minor variations; see tech sheet for details.
Research has shown plants supplemented with silicon have increased yields, even in prime growing conditions. Supplemental silicon strengthens plant cell walls and improves resistance to insects and disease.  Silicon also stimulates plants natural immune responses, increasing the production of resins and terpenes and improving drought/stress resistance.
