Absorption of nitrogen oxides into the soils were measured in a gas chamber by an automatic continuous nitrogen oxides analyzer (with Saltzman reagent). The capacity of absorption of nitrogen oxides differs greatly due to the sorts of the soils. The soils gradually released nitric oxide at room temperature, and the concentration of the released nitric oxide is nearly proportional to that of original gas concentration. Nitric oxide and nitrogen dioxide were released by heating from the wet soil which absorbed nitric oxide or nitrogen dioxide, while only nitric oxide was released from the dry soil. The temperature at which nitrogen dioxide appears lowered with increasing the water content of the soil. Some soils even reduced nitrogen dioxide to nitric oxide. The rate of absorption and release between the soils and the atmosphere varied by the sorts, temperature and water content of the soils.
