토양으로부터 휘발되는 암모니아와 이산화질소의 소시에 (消矢) 대한 식피형의 (植被型) 영향에 대하여 = Influence of Vegetation Type on the Intensity of Ammonia and Nitrogen Dioxide Liberation from Soil

다국어 초록 (Multilingual Abstract)

Losses of nitrogen in the gaseous form were determined with closed systems in the field under different vegetation types. Ammonia volatilization was greatest from the pine stand, and least from the sod stand, and was greatly reduced in all three sites in the rainy season due to the low temperature. There were only insignificant differences in the nitrogen dioxide volatilization from the soil of the three vegetation types. Losses of ammonia and nitrogen dioxide at various soil depths also showed little variation. Evidently the microbial activity responsible for the NO_2 loss was relatively unaffected by the changes in temperature and soil moisture content during the investigation.
