How to use it
- Enter field area and unit.
- Enter target seeds per square meter and germination rate.
- Adjust the optional waste factor and calculate.
Seed Rate Calculator
Estimate a seed count from area, target seeds per square meter and germination assumptions.
Important: This calculator provides estimates only. Actual agricultural results vary by crop, soil, climate, variety, equipment, and local practice. Always follow product labels, local regulations, and qualified agronomy advice.
About the Seed Rate Calculator
Convert field area into a target seed count and adjust it for entered germination and waste percentages.
Formula
Target seeds equal square meters times seeds per square meter. Divide by germination rate, then multiply by one plus the waste percentage.
Example
One hectare at 250 viable seeds per square meter targets 2,500,000 viable seeds before adjustments.
Notes
The output is a numerical estimate, not a crop-specific seeding recommendation. Seed size, variety, equipment and field conditions are not modeled.
