Have you used a soil pH amendment?

Soils with pH below 5.5 or above 8.5 can reduce canola yield potential, largely due to reduced nutrient availability. Amending soil with products such as lime to increase pH or elemental sulphur to lower pH can work, but it takes large volumes and a large investment.

We will look into the research for an upcoming Canola Watch article. In the meantime, we’d like to hear from you. Have you used lime or another amendment to increase pH, or elemental sulphur or something else to reduce pH? We’d like to know what you used at what rate, what cost, and whether it paid off.
