Abstract:
A simple closed system was set up for the measurement of CO//2, N//2O, and NH//3 emission from soil samples kept under well-oxygenated atmosphere. The system is an adaptation of a method sugested by Cornfield (1961a). Carbon dioxide is precipitated from the atmosphere as BaCO//3, while O//2 is generated from a BaO//2 solution in equivalent amounts. With the aid of the proposed method, the simultaneous and quantitative determination of the mineral N forms in soils, of the gaseous N forms, and of CO//2 may be performed even in well-oxygenated conditions. Tests carried out in incubated soil-sludge mixtures indicated that gaseous N forms may constitute a large fraction of the organic N ammonified. This may result in an underestimation of the mineralization potential of the organic N. Gas measurement may be needed where losses of N gases are likely or for the testing of the suitability of incubation techniques for the assessment of N mineralization capacities. The method is especially useful for the study of C and N dynamics in soil-sludge mixtures.
