Physiological and Ecological Aspects of Aerobic Denitrification, a Link with Heterotrophic Nitrificailable technology (e.g. sensitive oxygen — analyzing equipment, chemostats, mass spectrometers) has improved, it has been possible to establish that a number of strains do indeed denitrify while simultaneously respiring oxygen. This is, of course, not true of all denitrifiers. . appears to be the mo

Emissions of N2O from Various Environments — The Use of Stable Isotope Composition of N2O as Tracer is (1) a natural source of stratospheric NO, which is an important element in the ozone chemistry in the stratosphere (Crutzen, 1970; McElroy and McConnel, 1971; Johnston, 1972; Cicerone 1987), and (2) a greenhouse gas, like CO. and CH., contributing to the increase of average surface temperature of

Measuring Denitrification in Soils Using 15N Techniques, 1954). At that time, thirty years ago, .N or the use of artificial atmospheres were the only tools available to scientists interested in understanding the workings of denitrification in soil systems. Because of the expense of .N, limited access to mass spectrometer facilities, and the analytical d

Rhizosphere Denitrification; A Minor Process but Indicator of Decomposition Activityagnitude when moving from the bulk soil through the rhizosphere towards the root surface (Brown, 1975; Helal and Sauerbeck, 1986). The composition of the soil microbial population (Rouatt et. al., 1960) and its denitrifying capability (Smith and Tiedje, 1979) show dramatic changes over this small di

Characterizing the Variability of Soil Denitrificationwide variety of fairly novel statistical techniques have been applied to the study of soil variables in an attempt to characterize variability including i) geostatistics (Burgess and Webster, 1980; Vieira et al., 1983; Vauclin et al., 1983), ii) spectral and autocorrelation analysis (Kachanoski et a

In terms of the spatial distribution and extent of anaerobic conditions in soils and sediments, it is conve
