(square feet per acre) × Row Spacing 4. Adjust Seed Meter Settings: Using the seed count
per pound and seed size, set the planter's seed meters to dispense the correct number of
seeds per row foot. ---
Example Calculation:
Suppose the target plant population is 30,000 plants per acre, with 30-inch rows (2.5
feet). - Seeds per Acre = 30,000 × 2.5 = 75,000 seeds - Seeds per Row Foot = 75,000 /
43,560 × 2.5 ≈ 4.3 seeds The operator would calibrate the seed meters to dispense
approximately 4 to 5 seeds per foot, depending on seed size and germination rates. ---
Factors Influencing Seed Population Accuracy
Achieving the desired seed population involves multiple variables:
Seed Size and Weight
- Larger seeds tend to be fewer in number per pound, requiring adjustments to seed
meter settings. - Smaller seeds necessitate different calibration to deliver the same plant
