Deep Placement, One-Pass Fertilizer Rig

Deep Placement, One-Pass Fertilizer Rig FERTILIZER APPLICATION Fertilizer Application (58f) 22-2-25 After years of making two trips to apply dry fertilizer and knife in anhydrous ammonia in the fall, a Vinton, Iowa, farmer decided to combine the two jobs into one and to get the dry fertilizer placed deeper. "It was on of those cases of æwhy didn't I think of this sooner,'" says James Kirk, who solved the problem by putting together a deep placement rig from components he already had. He used a 6-row Deere planter toolbar and Deere dry fertilizer attachment to build the rig. "I moved the fertilizer boxes from the front to the rear of the 7 by 7-in. toolbar," Kirk says. "The only problem in doing so was that the fertilizer driveshaft interfered with the wheel lift cylinder, so I built spacers to move the boxes to the rear of the bar about 4 in. "I used the standard Deere dry fertilizer transmission and Deere plow coulters ahead of each anhydrous shank, which are on 30-in. spacings. "Dry fertilizer falls by gravity from the boxes through a plastic tube to pipes welded behind the anhydrous shanks." Although Kirk anticipated that moisture attracted to the anhydrous discharge might plug the dry fertilizer tube, it was not a problem, he says. The rig worked perfectly last spring and I plan to use it in the fall in bean stubble where possible," he says. Contact: FARM SHOW Followup, James Kirk, 6432 24th Ave,.
