Calculate seed needed per acre from plant target and germination.
Not every seed sprouts, so the target plant population is divided by the germination fraction to find how many seeds to sow. Undersowing wastes a season on thin stands, but overseeding wastes seed and creates overcrowding that cuts yield.
Seeding Rate
Seeds = target plants ÷ (germination ÷ 100); pounds = seeds ÷ seeds per lb

This calculator takes 3 inputs: Target plants per acre, Germination rate, Seeds per pound. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
