## Why use this tool

Separate losses show why the sowing quantity is greater than the final plant target.


## Before relying on the result

Expected averages cannot guarantee the final plant count. Use the seed lot and your own establishment record.


## Tool limitations

Expected averages cannot guarantee the final plant count. Use the seed lot and your own establishment record.

## Questions

### Does the seed count guarantee enough plants?

No. The calculation uses expected averages. Real germination and establishment can differ.

### What should I check before using Seed Quantity Calculator?

Check Final plants required, Expected germination, Survival after germination and Extra seeds. Use the exact units shown beside the controls and replace any example values with your own inputs.
