Tillage sets the stage. In Episode 3 of Corn College TV Farm Journal Associate Field Agronomist Missy Bauer uses multiple soil pits as her classroom to examine the differences in soil density.
“When roots hit a soil density change, it can cause them to turn,” Bauer says.
“It can be hard to bring water back up through layers.”
Chisel plows need good cross shatter from shank to shank. Bauer says be cautious of the “W” bottom, which can cause problems with plantability and even emergence.
“No matter what, ear count is the priority. If primary tillage isn’t done properly, you’ll go backwards. The depth of your chisel plow will depend on your soil and your chisel. The deeper you go the better it should look up top.”
Dig deep into the different types of tillage. Learn more in Episode 3 of Corn College TV.
