Attendees at the seventh annual National No-Tillage Conference in St. Louis, Mo., shared ideas on combining these products to increase weed control.
“Liquid nitrogen increases triazine herbicide activity.”
—Allen Berry, Nauvoo, Ill.

—Ray Rauenhorst, Easton, Minn.
“We go with a 28 percent liquid nitrogen carrier for non-herbicide weed burndown.”
—Mike Solberg, Colfax, Wis.
“Half our nitrogen goes down as a pre-plant liquid with herbicides. The rest is applied in dry form.”
—Joe Hottel, Burkittsville, Md.
“We apply 28 or 32 percent liquid nitrogen with added zinc just after no-tilling corn.”

“We use 10 gallons per acre of liquid nitrogen which acts as a starter. However, we increased the Roundup rate by 8 ounces per acre to offset fertilizer burn.”
—Mike Swaar, Mason City, Ill.
“We use 7 gallons per acre of 30 percent liquid nitrogen applied behind the no-till corn…
