How to Use This Calculator
  1. Enter Management Zones, Base Application Rate, and High Zone Multiplier.
  2. Set Low Zone Multiplier, Product Cost per Unit, and Field Size.
  3. Review Average VR Rate (units/ac) and VR Total Cost ($).
  4. Use Total Product Needed (units) and Flat Rate Cost ($) to inform your decision.
  5. Use the chart to visualize the results and explore different scenarios by adjusting inputs.

What each input means

Management Zones
Number of distinct application zones.
Base Application Rate
Average recommended rate for flat-rate application.
High Zone Multiplier
Rate multiplier for highest-potential zones.
Low Zone Multiplier
Rate multiplier for lowest-potential zones.
Product Cost per Unit
Cost per unit of applied product.
Field Size
Total field acres.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Management Zones = 4, Base Application Rate = 150, High Zone Multiplier = 1.3, Low Zone Multiplier = 0.7 = 6 input(s) provided
  2. Calculate Average VR Rate
    Average VR Rate
    150 = 150
  3. Calculate VR Total Cost
    VR Total Cost
    10800 = $10,800
  4. Calculate Total Product Needed
    Total Product Needed
    24000 = 24000
  5. Calculate Flat Rate Cost
    Flat Rate Cost
    10800 = $10,800
