Across Eastern Ontario, more farmers are exploring wollastonite to support soil health, enhance crop resilience, and improve field performance.
UNDO’s Ontario farmer program is built around local mineral-rich Canadian wollastonite from Seeley’s Bay, free soil testing, and professional spreading logistics that supports long-term soil health.
UNDO’s Farmer Program is funded through the sale of high-integrity carbon removal credits, allowing us to supply and spread the crushed rock at zero cost to farmers. Your farm remains your farm, and you continue to make the decisions that shape your operation.
Why Carbon Credits Are Part Of The Program
Wollastonite brings important agronomic benefits to the farms we work with. It provides calcium and plant-available silicon, supports stronger root development, helps crops withstand environmental stress, and can continue to support soil conditions over multiple seasons.
It also supports permanent carbon removal through enhanced rock weathering. As wollastonite naturally weathers in the soil, it reacts with water and carbon dioxide, helping remove atmospheric CO₂ and store it in a durable form over geological timescales.
That carbon removal can be measured and verified. Once verified, it generates carbon credits for UNDO. The sale of those credits is what funds the program, and enables UNDO to be able to purchase the rock, professional spreading, and complete the scientific work required to properly measure carbon removal.
That funding structure allows us to provide crushed wollastonite rock at no cost to farmers, except for haulage costs. In Kingston, the current 2026 haulage rebate and UNDO top-up go further, making the program zero-cost for eligible farms by removing haulage costs within the municipal boundary.
What A Carbon Credit Means
A carbon credit is a tradable certificate linked to the removal or reduction of one metric tonne of carbon dioxide from the atmosphere, or its equivalent in other greenhouse gases.
In the UNDO farmers program, the credits are linked specifically to carbon removal through enhanced rock weathering. When wollastonite is spread on farmland, it begins a natural chemical process that removes atmospheric CO₂ over time. If that removal is measured, supported by field data, and verified properly, it can be issued as a carbon credit.
This is different from treating a field as a broad environmental offset. In our program, the credit is tied to the wollastonite spread through the program and the removal associated with that rock as it weathers.
These credits are not generated immediately. They are issued over time as the rock breaks down, and the carbon removal can be quantified and verified. This complex process depends on field data, scientific analysis, and careful tracking from quarry to field.
Why UNDO Retains The Carbon Credits
UNDO retains the carbon credits linked to the rock alone and makes no claim to any other carbon associated with the land, such as reforestation or soil organic carbon.
That funding supports more than the supply of rock. It also helps cover the free-soil eligibility testing, professional spreading, scientific monitoring, and the broader work needed to deliver the program responsibly at scale.
For our farming partners, that also means that there is no need to find a buyer, manage carbon paperwork, or take on the technical side of carbon accounting. The farm receives all the on-farm benefits of the program, while UNDO manages the carbon credit side.
The carbon credits are linked specifically to the wollastonite spread through the program and to the date that the application takes place. They do not create an open-ended claim to the land itself, and they are not something the farmer can access, control, or sell separately outside the program. If land changes hands in the future, or if wider carbon markets continue to develop, that does not change the structure of the UNDO program linked to that original application. In practice, access to carbon markets for enhanced rock weathering is likely to continue through specialist programs, as demonstrating carbon removal requires detailed measurement, monitoring, and verification.
What Taking Part Does And Does Not Mean For Your Farm
Participating in the UNDO farmers program is entirely voluntary and doesn’t affect who owns or controls your land. You can keep your usual rotations, continue with your cropping plans, and make all your own decisions about your farm. Our goal is to support and collaborate with active farms, not to interfere with how you manage your land.
The program is designed to help farming partners enjoy the benefits of mineral-rich wollastonite, while the carbon credit aspect remains tied to the rock and the removal process we oversee.
What The Program Provides
Every farm participating in our program benefits from free soil testing, a key step in determining eligibility and ensuring the program is a great match for your land.
Through our standard Eastern Ontario program, we provide and professionally spread wollastonite on eligible farms at no cost for the material or spreading; farmers just cover the cost of haulage.
Within Kingston’s city limits, thanks to the 2026 Kingston Wollastonite Rebate and the UNDO top-up, the entire program becomes completely free for eligible farms, covering materials, spreading, and trucking. We take care of every part of the process, from field review and suitability checks to coordinating logistics and professional application, making it as easy and seamless as possible for you to get the benefits of wollastonite.
Who Is Eligible?
The Eastern Ontario Farming Program
Across the Eastern Ontario program, we generally prioritize farms within a workable distance of Seeley’s Bay, with a particular focus on land within roughly 150km of the mine.
In general, the program is best suited to:
– Farms with at least 25 acres available for application
– Soil pH conditions between 5.5 and 7.0
– Farms growing cereals, forage, vegetables, pasture, or other suitable crops
– Growers open to free soil sampling and basic field coordination
If your current pH is unknown, that is not a barrier to starting the conversation. Our team can conduct a free soil eligibility test and discuss whether the program is likely to be a good fit for your land.
The Kingston Rebate Farming Program
To access the fully subsidized Kingston program, the main requirements are:
– Land must be within the City of Kingston municipal boundary
– Fields should generally fall within the target pH range of 5.5 to 7.0
– Applications are intended for 25 acres or more
– Participation is subject to the available 2026 funding
– Applicants take part in the standard soil suitability assessment
Because the Kingston rebate allocation is finite and tied to the 2026 season, the team is currently working on a first-come, first-served basis as eligible farms come forward.
At the moment, rebates are limited to Kingston because the City has taken a leading role in supporting this kind of initiative. To our knowledge, no other municipality has introduced a similar carbon capture rebate. Over time, UNDO will be using the Kingston program as a case study to help bring more municipalities on board and expand access to similar support in other regions.
What Happens After You Register Interest?
We try to keep the process as straightforward as possible.
1. Initial Inquiry
The first step is simply getting in touch. That may be through the website, a conversation at an event, or a direct call with our team.
2. Follow-Up From The Team
Once we have your details, someone from the team will follow up to learn more about your farm, location, acreage, and the type of land you would like us to consider.
3. Free Soil Testing And Eligibility Check
If the farm looks like a good fit, we arrange a free soil test. This helps us understand the land’s baseline condition and whether wollastonite is likely to be a good match.
4. Review Of Fit And Eligibility
From there, we review the results with you and confirm whether the land meets the program criteria, including whether it falls within the Eastern Ontario program or the Kingston rebate scheme.
5. Logistics And Spreading Coordination
If the land is a good fit, we coordinate with you on the operational side, including delivery, timing, and professional spreading. The goal is to ensure the application aligns with your farm calendar as smoothly as possible.
6. Application
Wollastonite is delivered and spread with standard lime-spreading equipment. There is no need to purchase special machinery or redesign the farm plan for the application.
7. Follow-Up
After the application, we continue to manage the measurement and carbon-removal aspects of the program.
Designed To Work Alongside Your Farm
The UNDO farmers program aims to make the benefits of wollastonite accessible to more farms through practical, supported, and real-world field applications.
Carbon credits are a key part of the funding framework. UNDO manages the science, measurement, and verification for these credits, while our farming partners benefit from mineral-rich wollastonite on the ground, along with free soil testing and professional spreading.
For farms that are a good fit, the aim is to offer a straightforward path into the program, with clear information, local support, and a structure that aligns with normal farm operations.
