How to Use This Calculator

Enter Field Size, Number of Soil Zones, and Base Seeding Population.
Set High Zone Yield Potential, Low Zone Yield Potential, and Seed Cost per Bag.
Adjust Seeds per Bag as needed.
Review the High Zone Seed Rate (seeds/acre) result.
Use Low Zone Seed Rate (seeds/acre) and Average Seed Rate (seeds/acre) to inform your decision.

How the result changes with Base Seeding Population

Field Size: Total field area in acres.
Number of Soil Zones: Distinct management zones identified in the field.
Base Seeding Population: Target seed population per acre at average conditions.
High Zone Yield Potential: Relative yield potential of best soil zones as a percentage of average.
Low Zone Yield Potential: Relative yield potential of poorest soil zones.
Seed Cost per Bag: Price per bag of seed.
Seeds per Bag: Number of seeds in each bag (typically 80,000 for corn).
