Résumé :
|
The quantitative dependences of CO2 and N2O emission on soil water tension (P) were studied by the method of gas chromatography in four types of loamy soils-chernozem, soddy-podzolic, sierozem, and krasnozem (red ferralitic soil). The data on gas emission are expressed as a ratio (E-rel) of emission at a certain moisture tension to maximal emission noted for that soil.
