The experiments described in this report were conducted to determine: (1) the reactions that occur when liquid nitrogen dioxide is injected into various types of soil, (2) the magnitude of gaseous losses of nitrogen dioxide or its decomposition products from the soil, and (3) the possible accumulation of toxic decomposition products of oxides of nitrogen in the soil. The results of these studies lead to the following conclusions: (a) Injected liquid nitrogen dioxide is readily adsorbed by soil. Losses as gaseous nitrogen dioxide or nitric oxide are less than 1%. (b) In acid, neutral, or unbuffered alkaline soils, injected liquid nitrogen dioxide produces a sufficiently acid soil reaction to insure rapid and complete chemical oxidation to nitric acid. (c) In highly buffered alkaline calcareous soil the injected liquid nitrogen dioxide produces little change in soil reaction and is only partially oxidized to nitric acid. Approximately one third of the nitrogen injected exists temporarily as nitrous acid.
