A vehicle for applying nitrogen to the soil. The vehicle includes a pulling vehicle having a massive towing capacity and a tool bar coupled to the pulling vehicle. A large anhydrous ammonia tank is secured to the pulling vehicle and a pump is secured between the tank and the tool bar to move anhydrous ammonia from the tank to the tool bar, where the anhydrous ammonia is injected into the soil. By pumping the anhydrous ammonia, the present invention can be used to apply anhydrous ammonia to the soil in temperatures which would otherwise be too cold to effectively apply anhydrous ammonia using only vapor pressure.
