A method for marking the point of anhydrous ammonia release is described. A steel tube welded to the back of the ammonia applicator knife serves to place a twine marker at the point of release as ammonia is injected into the soil. The twine can then be readily located several months later if sampling of the ammonia application zone is desired.
