Target Seeding Rate

There are several things to consider for determining the best seeding rate for your farm. Our typical suggestion for most soils in Ontario is 1.6 Million Seeds per acre when planting at a "normal time" for your area. This ensures enough seed to cover germination ranges, natural mortality and normal overwintering loss.

For more detailed recommendations, see our suggestions below.
