Overview

• Stable, high yields across soil types
• An excellent choice for corn-on-corn acres at varying plant populations
• Very good drought tolerance
• Impressive late-season intactness
• High quality, high test weight grain

Placement/Management

Ear flex allows for high yields at varying populations. A solid option across soil types, including poorly-drained soils. An excellent corn-on-corn choice. Moves south as an earlier SmartStax® option.

Soil Adaptability

Rating Soil Category
E
Light Soils

LOW CEC (<10); OM <1.5%; low water-holding capacity; non-irrigated sand; marginal productivity; drought prone.

E
Medium Soils

EC 11–18; OM 1.5-3.5%; well-drained; silt loam; high productivity.

E
Heavy Soils

High CEC (>18); OM >3.5%; poorly-drained; high clay content; gumbo; muck

E
Poorly-drained Soils

Soils that have the potential to remain saturated for prolonged periods; side hill seeps; gumbo muck
