Pulling corn samples that are less than 1 foot tall (V4 to V6 stage) can provide perspective on overall soil fertility, Farm Journal associate field agronomist Missy Bauer says in Episode 12 of Corn College TV Season 3.
"We’re taking the entire plant from the surface of the soil up and collecting it to be able to send it to the lab," Bauer says.
