Why silica

Your plants deserve better defenses

Silicon is a beneficial element that supports how plants build structure and handle stress. Silifolia makes it easy to add — as a liquid or a granular soil amendment.

Stronger

Plant-available silicon builds sturdier cell walls — better structure and less lodging in the field.

Resilient

Research on wollastonite links added silicon to better moisture retention and drought resilience.

Protected

A stronger, silica-reinforced surface is part of a healthy plant’s natural line of defense.

Silifolia is a soil amendment. Field results vary with soil, crop and rate. See our how-it-works page for the research and what we can and can’t claim.

From waste to growth

Free tailings. Repurposed kettles. Local hands.

Our raw material is free wollastonite tailings — a calcium-silicate mineral left over from a nearby Ontario mine. Instead of sitting in a pile, it becomes food for soil.

We process it in semi-new kettles rescued from closed-down microbreweries, giving good equipment a second life. Small batches, made by neighbours, on the drumlin land north of Uxbridge.

It’s a genuinely circular story: mining waste and brewery gear, turned into stronger crops and healthier soil — with the potential to capture carbon as the mineral weathers.
