Your Fertilizer Program Is
Costing More Than It Should
Conventional fertilizer prices keep climbing — and buying lime separately adds another pass, another cost, and more time away from what matters. For Ontario row-crop operators running tight margins on corn and soy, every unnecessary input eats into your bottom line.
What if you could get your lime, nutrients, and organic matter in a single application — and spend less per acre doing it?
Meet N-Rich®
A CFIA-registered soil amendment manufactured by Walker Industries, with a 30+ year track record across Ontario farmland.
Lime — The #1 Differentiator
N-Rich delivers a high lime equivalency that raises soil pH in 2–4 weeks — not the 6–8 months you'd wait with conventional ag lime. One application replaces a separate lime program entirely.
Lower Cost Per Acre
By combining lime, nutrients, and organic matter into a single application, N-Rich eliminates redundant passes and separate product costs. The result: lower cost per acre than a conventional fertilizer-plus-lime program.
Bonus Nutrients Included
Every application also delivers nitrogen, phosphorus, potassium, magnesium, sulphur, and organic matter — nutrients your crop needs, included at no extra cost.
One Pass Does It All
