About this tool
Use tool ↑Convert a target stand and measured seed-lot quality into kg/ha and total seed mass.
For growers using a cleaned, single seed lot: enter the agronomic target, thousand-seed weight, tested germination, expected survival of germinated seeds and area. Required seed count equals target divided by both percentage fractions. Convert with seed weight. No crop recommendation, mixtures, coating correction or machine calibration.

Frequently asked questions
Does field survival already include germination?
No. Enter the fraction surviving after germination; otherwise losses are counted twice. Use a suitable local agronomic target.
