Scientific research supports and demonstrates many unique benefits wollastonite use has on a wide range of crops and soil types.

We collect and summarize observations from growers using Canadian Wollastonite. Feel free to contact us with your experience or questions.

Wollastonite In the soil




Longer Shelf Life Lettuce, Cauliflower, Broccoli, Cabbage, Strawberries Less spoilage, better inventory management
Increased Yield Annual Herbs, Spinach, Lettuce More cuts in with and without comparison, better regrowth
Extended Length of Harvest Kale, Collards Increased yield per bed foot and profitability
Enhanced root growth Lettuce, Tomatoes, Chinese Cabbage, Spinach Observed in with and without comparison
Reduced lodging Peppers Reduced labour cost, improved fruit yield and quality
Reduced damage from slugs Salad Greens, Cabbage, Broccoli, Cauliflower Drastically reduced slug presence and damage
Less crop loss to disease Strawberries, Tomatoes Extended the harvest period with less disease pressure which increased the profitability of the crop
Longer Shelf Life Lettuce, Cauliflower, Broccoli, Cabbage, Strawberries Less spoilage, better inventory management
Reduced transplant shock  Mixed vegetables Seedlings recovered faster, better quality overall
