Estimate crop yield per acre from harvested weight and field area. Calculate bushels, tons, and yield per hectare for grain and commodity crop reporting.
Calculate field area in acres and hectares from dimensions or GPS coordinates. Estimate planted acreage for farm planning, inputs, and yield reporting.
Calculate irrigation water volume in gallons and acre-inches from field area and application depth. Plan pivot, drip, and flood irrigation scheduling.
Increase seeding rate to account for germination and field loss. Typical emergence 90–95% on good seedbed.
Seeds/Acre = Target Plants/Acre ÷ (Germination % × Emergence %)Seed size varies by hybrid and lot — use seed tag seeds/lb for each lot.
Lb/Acre = Seeds/Acre ÷ Seeds per PoundConvert to seeds per foot for planter calibration on 30″, 15″, or other row spacing.
Seeds per Row Foot = (Seeds/Acre × Row Width ft) ÷ 43,560Updated: July 2026
35,000 seeds/ac at 95% emergence with 95% germination. 2,800 seeds/lb → 12.5 lb/ac seeding rate.
Drill or row soy at 150,000 seeds/ac accounting for loss. 2,800 seeds/lb → ~54 lb/ac.
30″ rows: 35,000/ac → 35,000×2.5/43560 ≈ 2.0 seeds per foot row. Verify with tray test.
Determine seeding rate in pounds or seeds per acre from target plant population, row spacing, and seed characteristics. Enter desired final stand, germination percent, and seeds per pound to calculate planter settings.
