Abstract:

The applicator includes a blade member having a forwardly directed cutting edge. Secured to the rear edge of the blade member is a first tube having a horizontal discharge opening at its lower end via which anhydrous ammonia is introduced into a furrow. Secured rearwardly of the first tube is a second tube having a horizontal open end via which a phosphoric acid is introduced concurrently into the same furrow. Both discharge ends reside in parallel planes, the first discharge end being at a lower elevation than the second discharge end. The method of concurrently applying both anhydrous ammonia and a phosphoric acid results in increased yields as far as small grain crops are concerned.
