The injector foot targets the liquid NH3 stream flow precisely. The stream width is .070 inch diameter and opener slot is . 375 inch width. The closing wheels control the depth of the opener and allow the parallelogram linkage design to hug the ground line. The Exactrix Injector Foot is unique in the application of NH3 .
Residue does plug the opener since there is no shank.
There is less soil fracture with the Exactrix Injector Foot and thus less tillage. This reduces horsepower and allows for an ideal No-till seed bed. NH3 can now be placed shallower than ever. The Fertilizer Institute recommends that NH3 be placed no shallower than 2.5 inches. Greg s NH3 placements were made at 4 inches.
