An apparatus is disclosed which is useful for mixing ammonia, in a vapor-liquid phase, with an additive composition, in a liquid phase, to obtain a homogeneous vapor-liquid mixture of the anhydrous ammonia and the liquid additive compound. The apparatus described herein is particularly suitable for use in a field applicator, for applying the anhydrous ammonia to the soil, as a nitrogen fertilizer, in combination with an additive, such as a nitrogen stabilizer. In operation, the vapor-liquid ammonia stream is metered through a meter regulator and then passed downwardly into a mixing chamber. Below the meter regulator is a delivery tube through which the liquid additive is metered into the ammonia stream before entering the mixing chamber. Inside the mixing chamber the ammonia-additive stream is further mixed to obtain a homogeneous mixture, which is then passed downwardly into a distribution chamber. From this chamber the mixture is delivered to a use point, such as a row of soil knives in a field applicator.
