Soybean Yield Estimator
Enter plant population, pods per plant, seeds per pod, and 100-seed weight to estimate soybean yield in bu/ac and t/ha plus total harvest tonnage.
Yield Components
Enter to calculate total harvest weight for your field.
Narrow-row target: 130,000–160,000 plants/ac. Wide-row: 90,000–120,000 plants/ac.
Count all pods with at least one seed. Typical range: 20–80 pods/plant depending on population and branching.
Most varieties average 2.5–2.8 seeds/pod. Count seeds in a representative sample of at least 30 pods.
Weigh exactly 100 air-dry seeds. Typical range: 13–20 g. Standard bushel = 60 lb.
Enter to calculate estimated gross revenue per acre.

Calculation Breakdown
Summary
Enter plant population, pods per plant, seeds per pod, and 100-seed weight to estimate soybean yield in bu/ac and t/ha plus total harvest tonnage.
How it works
- Enter the field area in acres or hectares depending on your selected unit mode.
- Enter the plant population — count plants in several 1-meter row sections and extrapolate.
- Enter the average pods per plant — sample at least 10 representative plants across the field.
- Enter the average seeds per pod — most soybean varieties average 2.5 to 2.8 seeds per pod.
- Enter the 100-seed weight in grams — weigh 100 air-dry seeds and record the result.
- Click Estimate Yield to see yield in bu/ac and t/ha, plus total harvest for the entered area.
Use cases
- Pre-harvest scouting to forecast soybean production for elevator contracts and bin planning.
- Comparing yield potential across varieties, seeding rates, or management zones.
- Estimating total harvest tonnage to plan trucking and grain storage logistics.
- Evaluating the impact of late-season stress, disease, or pod abortion on final yield.
- Teaching agronomy students the standard soybean yield component method.
- Documenting field yield components for farm records and crop insurance claims.
- Benchmarking combine yield against pre-harvest estimates to calibrate future scouting.
- Quick what-if analysis for different planting densities or expected pod-set scenarios.
