Abstract
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.
Claims14
An apparatus for application of anhydrous ammonia fertilizer to soil, said apparatus comprising
- knife means adapted to be propelled forwardly along the surface of said soil while penetrating said soil to a predetermined depth, for opening an elongated substantially continuous furrow in said soil;
- dispensing means associated with said knife means for continuously dispensing a predetermined quantity of anhydrous ammonia into said furrow as said knife means is propelled forwardly;
- spray means for dispensing a substantially continuous spray of an absorbent liquid into said furrow in a pattern designed to substantially fill the confines of said furrow above said anhydrous ammonia dispensed into said furrow as said knife means is propelled forwardly,
- whereby said absorbent liquid spray will tend to reduce evaporative loss of said dispensed anhydrous ammonia from said soil.
A method for dispensing anhydrous ammonia fertilizer into soil, said method comprising:
- forming a substantially continuous elongated furrow in said soil;
- dispensing a predetermined quantity of anhydrous ammonia into said furrow;
- spraying a predetermined quantity an absorbent liquid into said furrow in a pattern designed to substantially fill the confines of said furrow above said anhydrous ammonia dispensed into said furrow to reduce evaporative loss of said dispensed anhydrous ammonia from said soil.
