Calculate required seed count, seeding rate (kg/ha or lb/acre), and bag estimate from row spacing, plant spacing, and germination (or target plants).
Use this when germination is uncertain.
| Germination | Required seeds | Required weight | Bags |
|---|---|---|---|
| -- | -- | -- | -- |

Results vary by cultivar, seed quality, equipment accuracy, soil moisture, pests, and birds. Use as a planning estimate and adjust to local guidelines and field conditions.
You can use an estimate. The tool also shows results at ±10% germination so you can judge uncertainty.
Enter bag weight to calculate bags (fractional) and purchase estimate (ceil).
Switch ha/acre, cm/in, and kg/lb. Values are converted automatically on toggle.
Seed count is still calculated. For weight, enter TSW or the seeds per weight from the bag or spec sheet.
Switch to target plants and enter the desired plant density.
