ABSTRACT:
A combined plow and anhydrous ammonia fertilizer dispenser wherein the ammonia tank is connected to the plow so as to be drawn over unplowed ground. Hose means lead from the tank to the individual plow blades and dispense fertilizer beneath the soil being turned over in the furrows. The hoses are held in position by novel wear-reducing clamps. A further embodiment combines a chisel plow and fertilizer dispenser. The plow blades have hoses mounted thereon by clamps. Some of the plow blades which are located rearwardly of other plow blades push the dirt into the furrows cut by the forwardly located plow blades and also cover the exhaust end of the hoses with dirt causing the fertilizer to be retained in the soil.
