ABSTRACT:
An anhydrous ammonia knife including a shank attached to an implement tool bar, a knife segment attached to the forward edge of the shank, and an ammonia delivery tube disposed between the forward edge of the shank and the leading edge of the knife segment. The knife selectively penetrates the soil to a predetermined depth and the tube discharge end is disposed in fluid communication with the soil. Ammonia is discharged into the soil at a position immediately behind the leading edge of the knife segment as the furrow is first opened. This positioning minimizes the amount of ammonia vapor lost to the atmosphere since the ammonia is quickly entrapped in the soil.
