Once you choose a target plant density, use the actual 1,000 kernel weight and germination of the seedlot to calculate your seeding rate.
1) Choose a desired plant population range. For winter wheat, that’s 25 plants per square foot.
2) Count out 1,000 seeds and weigh them (in grams). This is a great activity for the kids to help with.
3) Estimate a seedling survival rate, which is the germination percentage minus a small amount for seedling mortality (usually five to 20 per cent for cereals. It’s much higher for canola). A common range for estimated cereal
