For side-dressing NH3 into corn ground, this producer chose a 2987 Magnum. It was end of June when I went to Western Kansas to get these pics and video, which was a little late in the season compared to past years—the weather had been very wet. The grower was almost done side-dressing . . . had already done around 4000 acres.
The Magnum units were mounted on a 62 ½ foot toolbar. This grower applied 75 pounds of NH3 on 30-inch centers. Because the Magnums have a single-disc design and low draft requirement, the growers were able to run at 9 mph.
Another grower used 2987 Magnums to side-dress 1,000 acres of corn in West-Central Illinois. His nutrient mix called for 100 pounds of NH3 applied on 60-inch centers. He was able to apply at 8 to 9 mph. Despite the late date because of all the rain, he said the units performed very well.
The ground seemed kind of wet, but everything was still sealing well.
A third producer in from Central Illinois used 2987 Magnums to side-dress NH3 on his corn. He was happy to be able to run at 9 mph while putting down between 100 to 150 pounds of nitrogen on 60-inch centers.
