With cool wet soils, growers may be tempted to plant the seed a little more shallow than normal, thinking that it would help with emergence to get the corn plant growing more quickly. Don’t do it!
A healthy productive corn plant needs a great foundation to support itself and massive root development to furnish water and nutrients. Keeping the planting depth at 2 inches allows the crown and secondary roots to be securely in the soil. The extra day that it may take for emergence is well worth the payoff.
