As corn planting gets underway across New Jersey with improving soil temperatures and field
conditions, achieving a uniform stand remains critical for protecting yield potential. Planting depth plays a key role in ensuring even emergence and strong early growth.
Recommended Practices
- Aim for a planting depth of 1.5 to 2.0 inches under most conditions
- In dry surface soils (common in sandy South Jersey fields), planting can be adjusted slightly deeper, up to 2.5 inches, to reach moisture
- Ensure consistent depth across the field for uniform emergence
- In cool or wet spring conditions, consider staying closer to 1.5 inches to avoid delayed
emergence
Points to Avoid
- Avoid planting shallower than 1 inch, which can lead to poor root development and drought sensitivity
- Avoid planting deeper than 2.5 inches, especially in cool soils, as emergence may be delayed
- Avoid inconsistent planting depth, which often results in uneven crop stands
- Avoid placing seed in dry soil without moisture contact
Key Message
Consistent planting depth, generally 1.5 to 2.0 inches in New Jersey
conditions, helps ensure uniform emergence, which is the foundation for strong yield potential.
