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.

Our Seeding Rate estimate can help you set up your seeding equipment to reach the proper seed rate. If your seed drill has a scale, or a lbs/acre chart, utilize the lbs/acre number. You can either drive over a hard mat, or hold up a closing wheel to utilize the seeds/ft or row number. Every piece of equipment will be different.

Stand Assessment Calculator

Walk your field in the spring and assess your wheat stand. This tool can assist you in making management decisions for the crop to get you to an ideal stand of wheat.

Learn about spring stand assessment

Plant Density

Measure one foot of a row and count the plants within that measurement.

Evaluate Stand Ideal Stand Very Strong Stand

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.
