Within the last decade the use of anhydrous ammonia as a source of nitrogen for plants has gained considerable popularity in the United States of America. Several workers have investigated crop response to gaseous ammonia in comparative studies between the gas and solid nitrogenous fertilizers. Field and laboratory studies involving the capacity of the soil to retain ammonia-nitrogen applied as a gas or in solution have also been conducted. Still other workers have investigated the effects of varying concentrations of ammonia-nitrogen upon soil microorganisms and the nitrifying capacity of soils.
