Planting Depth Vital to Even Emergence of Corn

Proper planting depth ensures seed corn gets adequate moisture and also helps provide good seed-to-soil contact, according to Missy Bauer, Farm Journal associate field agronomist.

Bauer says as a rule of thumb proper planting depth will range from 1 ¾" to 2" deep.
"We say that is the range because that is where we typically see good consistency with soil moisture," Bauer says. "Also, the crown of the plant is at ¾" below the soil surface so if you get too shallow, you won’t get good crown root development."
To check depth, Bauer says the best way is to dig behind the planter. "Get in the row, start scraping soil back, and look for seed but don’t knock the seed out as you scrape," she says. "Then take something flat and lay it level across the furrow and then measure down to the seed."
Bauer provides some additional thoughts on soil planting depth in the following video.

Farmers in much of the Eastern Corn Belt are just now revving up to plant their 2012 corn crop.  As they head to the field, Missy Bauer, Farm Journal associate field agronomist, encourages them to keep an eye on soil temperature, which can fluctuate widely this time of year.
