For over 3 decades, Clark Agri Service has stood alongside Ontario’s farmers—supporting the land, the families, and the legacy behind every operation. With roots in Canadian agriculture reaching back nearly a century, we’re proud to deliver the service, expertise, and care that help turn generations of hard work into lasting success.
Farmers know that every season brings new challenges—and new opportunities. That’s why we’re committed to offering the services, products, and insights that help maximize your yields and support your success year after year. From soil testing to field support, we’re here to better understand your operation and its unique needs.
Now with locations in both Wellandport and Waterford, we’re proud to serve more Ontario communities—offering local support with deep agricultural roots.
What you put into your soil directly impacts what you get out of it. That’s why, on our own farms, we rely on only the best seed, fertilizer, and crop protection products available. At Clark Agri Service, we offer those same industry-leading solutions—trusted by our team and proven in the field—so you can grow with confidence.
A great crop starts with quality seed—but it takes more to see it through. Backed by decades of experience, our Agronomy team delivers the crop inputs, services, and horticulture expertise you need to build a stronger, more resilient operation. From planting to harvest, we’re here to help you protect your investment every step of the way.
