📋 Case Study
Australian Broadacre Wheat Harvest Optimization
Yield variability >18% across fields despite identical settings; suspected sensor drift and calibration mismatches
🏗️ Project Overview
Integrated fleet of 38 New Holland CR10.90 combines and Case IH 1400 sprayers across 400k ha
🎯 Challenge
Yield variability >18% across fields despite identical settings; suspected sensor drift and calibration mismatches
🔧 Design Approach
Applied ISOXML schema validation + SPN scaling correction across all harvest and application logs; recalibrated yield mass flow (SPN 513) and grain moisture (SPN 518) using field-truthed offsets

📐 Key Calculations
Moisture Calibration Offset
Field Moisture – Reported Moisture
Result: -1.2%
Corrected over-application of drying energy
Yield Mass Flow Scaling Factor Adjustment
Calibration Factor = Measured Yield / Reported Yield
Result: 1.047
Reconciled 4.7% under-reporting bias
📊 Results
Yield variability reduced to 6.1%, fuel use per ton decreased by 9.2%, post-harvest drying costs cut by $1.8M annually💡 Lessons Learned
- •ISOXML version mismatch caused task file misalignment
- •SPN 518 (grain moisture) requires temperature-compensated scaling
- •Field validation must precede fleet-wide scaling updates
