Method and apparatus for applying dry fertilizer and anhydrous ammonia in a common band

Abstract

Abstract METHOD AND APPARATUS IS DISCLOSED FOR CHEMICALLY COMBINING A DRY FERTILIZER AND ANHYDROUS AMMONIA IN A BAND AT A PREDETERMINED DEPTH BENEATH THE SOIL SURFACE. A PLOWING KNIFE IS INTRODUCED INTO THE SOIL AND PULLED BY A SURFACE TRACTION VEHICLE TO FORM A CHANNEL OF PREDETERMINED DEPTH. A BAND OF DRY FERTILIZER IS DEPOSITED IN THE BOTTOM OF THE CHANNEL BY THE PLOW VIA A CONDUIT EXTENDING LONGITUDINALLY OF THE KNIFE, AND ANHYDROUS AMMONIA CONTACTS THE DEPOSITED DRY FERTILIZER AT A LOCATION BEHIND THE DEPOSITED DRY FERTILIZER. THE ANHYDROUS AMMONIA IS CARRIED BY MEANS OF A CLOSED CONDUIT ATTACHED TO THE REAR OF THE KNIFE AND SLIGHT REARWARDLY INCLINED AT ITS LOWER END SO THAT THE POINT OF APPLICATION FO AMMONIA TO THE BAND IS AT A LOCATION REARWARD OF THE SHANK. ATTACHED TO ONE SIDE OF THE PLOW KNIFE IS AN INVERTED MOLDBOARD FOR GATHERING SOIL FROM THE SIDE OF THE KNIFE AND ROUTING IT BEHIND THE KNIFE OVER THE POINT OF APPLICATION OF AMMONIA REARWARD OF THE KNIFE TO COVER THE AMMONIA AND PREVENT ITS ESCAPE IN GASEOUS FORM INTO THE ATMOSPHERE. A SECOND INVERTED PACKING MOLDBOARD IS ATTACHED TO THE OTHER SIDE OF THE KNIFE FOR GATHERING SOIL AND ROUTING IT BEHIND THE KNIFE AND PACKING IT DOWN ABOVE THE POINT OF APPLICATION OF THE AMMONIA.
