Detailed explanation-1: -Planting corn to a depth of 1½ to 2 inches is optimum for nodal root development.
Detailed explanation-2: -Check planting depth when starting each field. In summary, corn should never be planted less than 1.5 inches deep, 1.75 to 2.25 inches is an ideal target, but depending on soil type and conditions, may be planted up to 3 inches deep without any effect on stand establishment. Have a safe and successful planting season.
Detailed explanation-3: -On average, corn roots grew about 2.75 inches per leaf stage to a maximum depth of 60 inches (Figure 1). Going into more specifics, corn roots initially increased at a slow rate (0.29 in./day) up to 5th-leaf and from then on with a rate of 1.22 in./day until silking stage when maximum depth is reached.
Detailed explanation-4: -Plants should be spaced 8-10 inches apart between plants. For early plantings, seeds should be no deeper than 1 inch. For later plantings, plant seeds 1-2 inches deep to ensure adequate moisture contact. Each corn planting will be mature for only a short time: 7-10 days.
