πŸ—οΈ Project Overview

1,200-acre no-till corn-soy rotation in central Illinois

🎯 Challenge

Persistent surface ruts and reduced root penetration in 2022 wet season

πŸ”§ Design Approach

Switched from 20.8R42 duals to 23.1R30 singles with 15% lower inflation; added real-time load monitoring

πŸ“ Key Calculations

Peak Pressure Reduction

(P₁ βˆ’ Pβ‚‚)/P₁ Γ— 100
Result: 28%
Dropped below 120 kPa critical threshold for loam soils

Rut Depth Prediction

f(Peak Pressure, Moisture, Bulk Density)
Result: 1.7 cm (vs. measured 1.9 cm)
Within Β±10% field validation accuracy

πŸ“Š Results

Root zone porosity increased 12%, yield gain +3.8 bu/ac, fuel use down 6.2%

πŸ’‘ Lessons Learned

  • β€’Inflation pressure tuning has greater impact than tire size alone
  • β€’Moisture-dependent thresholds require dynamic adjustment
