Canadian Farmers & Landowners

Join a growing network of Canadian farmers and landowners using wollastonite to improve soil health, boost yields, and cut costs. We supply and spread this mineral-rich crushed rock on agricultural land free of charge; the farmer simply covers the cost of trucking.

Unlock The Power Of Wollastonite

Wollastonite is a sustainable soil amendment sourced locally in Ontario and rich in essential micro and macronutrients. It is applied with a standard lime spreader at a time that is convenient for you and has been approved for use in organic farming systems.

A Cost-Effective Alternative to Lime

Wollastonite has a liming effect, raising and stabilising the pH of your soil for multiple growing seasons. By gradually releasing alkalinity, it keeps soil conditions optimal for longer, maximizing the effectiveness of other fertilizers while cutting lime input costs.

Strengthens Crops and Boosts Yields

As the rock breaks down, it rapidly releases essential nutrients such as calcium, silicon and magnesium, reducing reliance on synthetic fertilizers. These improve root growth, support nutrient uptake and ultimately increase yields.

Natural Pest and Disease Resistance

Silicon has been scientifically proven to strengthen plant cell walls, increasing tolerance to pests, diseases and drought. Field trials have shown that wollastonite can also slow the spread of fungal diseases such as powdery mildew.

Co-benefits for Your Farm and Community

By reducing the reliance on synthetic fertilizers and lime, you’re helping keep our planet fit for future generations.

Soil and Crop Health

Wollastonite improves soil structure and stabilizes pH for up to three years. Rich in calcium and silicon, it strengthens plant roots, enhances nutrient availability, and supports fertilizer efficiency, leading to healthier, more resilient crops.

Local Communities

Our program prioritizes local partnerships, working with Canadian contractors to provide spreading services and reduce lime costs for farmers. By collaborating with local talent, we bring green jobs to rural areas, supporting regenerative agriculture and boosting economies.

Sustainability and Carbon Capture

Wollastonite is more than just a soil amendment; it permanently captures CO2 from the atmosphere via a natural process called enhanced rock weathering (ERW). A win-win for farmers and our planet.

The Nutrient Composition of Wollastonite

View the full breakdown →

Calcium

24.6%
Essential for strengthening plant cell walls, making crops more resistant to disease and environmental stress. It’s crucial for root development, improving nutrient uptake.

Silicon

59.2%
Known as the “resilience nutrient,” silicon helps plants withstand drought, pests, and diseases. It also enhances nutrient uptake efficiency, making fertilizers more effective.

Magnesium

5.76%
A key component of chlorophyll, magnesium, supports photosynthesis, energy transfer, and healthy leaf development, maintaining overall crop health.

Sulphur

1.6%
A vital component of plant proteins, promoting the formation of essential amino acids to support plant growth; it’s also involved in photosynthesis.

Potassium

1%
Supports root growth and improves drought resistance. Although present in smaller quantities, potassium plays a critical role in plant water regulation and stress tolerance.

Iron

2.6%
Enhances chlorophyll synthesis and oxygen transport within plants, promoting vigorous growth and healthy foliage.

Manganese

0.05%
An important co-factor for photosynthesis and hormone synthesis, manganese supports healthy root development and enzyme function.

How to Join the Program

We work directly with farmers as partners, not as customers. Unlike a traditional input supplier, UNDO doesn’t sell rock by the bag. Instead, our program members get access to free soil testing, spreading, and ongoing monitoring of their agronomic benefits while UNDO manages the carbon removal process in the background.

Eligible farms are within a 150 km radius of our partner site, Canadian Wollastonite, in Ontario. We focus on this region to reduce the carbon footprint of our operations while ensuring cost efficiency for you. However, there may be occasions where we can extend beyond this, so do get in touch.

We’ll take soil samples before and after spreading and will share these results with you, giving you insights into the long-term impact on your land and crops. We are partnering with farmers who have a pH of 6-7 to maximize the benefits for farmers and carbon removal for our planet.

Wollastonite is applied at 2–4 tonnes per acre using a standard lime spreader. We follow the Canadian spreading season, with peak operations in the Spring, Summer and Fall. We spread before or after harvest to ensure whole, healthy, and intact crops.

Wollastonite is provided at no cost to farmers – your only expense is trucking. In many cases, trucking is subsidised as part of our program. This makes wollastonite a highly affordable and valuable alternative to inputs such as lime and artificial fertilizers.

Farmers Leading the Way to a Healthier Planet

ERW has the potential to lock away up to 4 billion tonnes of CO2 per year – 40% of global targets – and Canada is leading the charge. Proven in lab and field experiments at universities around the world, ERW makes agriculture part of the solution to climate change.

STRONGER SOIL. HEALTHIER CROPS. LOWER INPUT COSTS.

Empowering Canadian farmers with natural solutions that boost productivity and support long-term land resilience.

Join Our Canadian Farmer Program

Canadian farmers are turning to wollastonite to optimize their land and improve profitability. Our program makes it easy – providing free spreading, soil testing, and subsidized trucking so you get the most out of every application.

With a simple, hassle-free process, you can improve soil structure, enhance nutrient availability, and reduce reliance on synthetic inputs.

Frequently Asked Questions

Lime provides a quick pH adjustment, but its effects wear off quickly, requiring frequent applications. Wollastonite raises and stabilises pH for longer while also releasing key nutrients like calcium, magnesium, and silicon for lasting soil health and crop resilience.

Wollastonite is most effective in moderately acidic to neutral soils but can provide benefits in a range of conditions. We are partnering with farmers who have a pH of 6-7 to maximise the benefits for your land and carbon removal for our planet.

Wollastonite is suitable for all crops, including pasture, and has been approved by respected organic certification bodies such as OMRI. Research trials have demonstrated increased yields in crops like wheat and pastureland. Wollastonite also improves root strength, enhances nutrient uptake, and boosts resilience to environmental stresses like drought and disease.

We cover the cost of supplying and spreading the rock. We simply ask the farmer to pay for trucking, which is calculated based on the location of your farm. Trucking is subsidized in many cases.

Some benefits, such as pH stabilization and improved soil structure, are noticeable in the first season. Others, like increased crop resilience and nutrient availability, continue to develop over multiple growing cycles.

Wollastonite is spread using standard lime-spreading equipment, making it easy to integrate into current farm operations. Typically applied at 2–4 tonnes per acre, we follow the Canadian spreading season, with peak operations in the Spring, Summer and Fall.

The program is funded by the sale of carbon removal credits. By spreading wollastonite on farmland, we capture and store CO2 from the atmosphere. Our farmers enjoy the soil and crop benefits, while the carbon credits are sold on the voluntary market to fund and scale this initiative.

It’s simple! Contact our team to check your eligibility. We’ll assess your farm’s location, soil type, and spreading logistics to confirm if wollastonite is the right fit for your land.
