In a method and apparatus for applying anhydrous ammonia fertilizer to soil, a soil penetrating knife produces a substantially continuous elongated furrow in the soil for receipt of the anhydrous ammonia; a dispensing tube associated with the knife dispenses liquid anhydrous ammonia continuously into the furrow and second tube associated with the knife continuously dispenses a spray of an absorbent liquid into the furrow for absorbing liquid and gaseous anhydrous ammonia to thereby reduce evaporative loss of anhydrous ammonia from the soil.
