Get Wollastonite, Get the power of Calcium + Silicon

We cover the cost of spreading and the wollastonite 

Farm pays for trucking


Wollastonite (CW) offers a unique blend of nutrients that can replace lime with a balanced ratio of calcium and magnesium and plant available silicon. Silicon reduces pest and disease pressure and increases tolerance to drought and temperature extremes in a wide variety of crops. When CW  is spread on your fields, hundreds of tonnes of CO2 are permanently captured as inorganic carbon within 12 months. This carbon capture is used to subsidize the cost of the wollastonite and spreading.



  • Replace lime with CW
  • Spreading is paid for
  • Does not need incorporation
  • Use your fields to permanently capture 1000’s of tonnes of CO2
  • Boost yields and reduce costs



  • CW releases calcium like lime but will not move pH above 7
  • CW is composed of calcium, silicon, magnesium, potassium, sulphur, and micronutrients
  • Silicon is known to boost yields, improve crop quality, and reduce pest and disease damage
  • CO2 is captured when CW reacts with weak acids in rainwater to form bi-carbonate ions that flush down into the soil and eventually oceans for permanent storage
  • Use 1.3 mt of CW to replace 1 mt lime (75% CCE)
  • Wollastonite is registered with the Canadian Food Inspection Agency (CFIA) and certified as an organic approved input in both Canada and US through the Organic Materials Research Institute (OMRI).



  • Fields located in Ontario
  • pH above 7 – soil tests available
  • Sign carbon capture agreement
