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 .
