Wollastonite - a calcium inosilicate mineral that may contain small amounts of iron, magnesium, and manganese substituting for calcium. Silicon is not traditionally considered for plant growth, but plants supplemented with silicon often yield better (even in prime growing conditions). Silicon strengthens cell walls, which reduces lodging and improves resistance to insects and disease. Calcium is essential to plant growth; Silicon stimulates immune response pathways (possibly increasing production of resins and terpenes); and reduces transpiration (improving drought resistance).
