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.

7 plants/ft or less - terminate it.

8 to 10 plants/ft - Carefully weigh alternatives.
Check for uniformity. Quantify your winter kill or drown out areas. Check for seeds sitting on top of the soil (clingers) that might not make it. Understand your reseeding options. Understand your Crop Insurance procedures if you wish to terminate the stand.

11 plants/ft or more is worth keeping. Ideal stands with full yield potential for your soil type and area. Manage for success.

Assessment: Encourage Tilling

Early Nitrogen and Sulphur at first opportunity will help create tillers. Nitrogen in ammonium form is preferred for quick release and uptake. If managed properly, can provide the opportunity for strong yield potential.

Assessment: Ideal Head Count

Serious yield potential for your area and soil type. Manage for success.

Assessment: Manage Lodging

A Seriously Thick Stand. Consider a PGR. (Check lodging score for varieties) Strongly consider split applications of nitrogen, or delayed first application on first N pass to discourage further tillering.
