Corn Planter Attachment Effects on Soil and Residue

“…A recent research experiment by Iqbal (1995) was conducted to measure the effects of coulters on soil conditions in the seed furrow and on early com growth. Planter treatments were the use of three fluted coulters, one bubble coulter, or no coulter immediately ahead of the planter's double-disc seed opener.…”
