⬡ MAIZSIM · G×E×M Framework

🌽 MAIZSIM Corn Yield Simulator

Simulate corn grain yield using MAIZSIM's G×E×M framework — integrating hybrid maturity, temperature × water stress, nitrogen inputs, and management into a season-long production forecast grounded in USDA-ARS ACSL mechanistic model science.

Optimal range: 28,000–36,000 plants/acre
Each stress day reduces yield 5–8% (MAIZSIM)

⬡ MAIZSIM · Temperature × Phenology

🌡️ Heat Stress & Phenology Risk

Evaluate temperature × photoperiod effects on corn developmental stages. MAIZSIM models heat stress impacts on germination, silking, pollination, and grain fill — the critical windows where temperature determines yield outcome.

Critical threshold: 95°F. Pollen kill above 100°F.

⬡ MAIZSIM · N Dynamics · 2DSOIL

🧪 Nitrogen Uptake & Use Efficiency

Simulate corn nitrogen uptake, remobilization, and NUE using MAIZSIM N dynamics coupled with 2DSOIL solute transport. Identifies NUE gaps and optimal split-application timing to maximize N recovery.

Each 1% OM releases ~20 lbs N/acre/year
