Proper corn seed planting depth is critical for optimum root and plant development.

Shallow-planted corn can delay or inhibit the development of nodal roots (braceroots), which are the primary roots for water and nutrient uptake. Planting corn seed to a depth of 1½ to 2 inches is optimum for nodal root development. If corn is planted too shallow and the topsoil becomes dry or cloddy, a condition called “rootless corn syndrome” can develop. Plants fall over due to the lack of nodal root development in hard or dry soil. Also, shallow planting depths of less than one inch expose corn seedlings to herbicides, increasing the potential for crop response.
