Gaseous phase: The air filled pores constitutes the gaseous phase of soil system and dependent on that of the liquid phase. The N and O2 contents of soil air are almost the atmospheric air but the concentration of CO2 is much higher (8 – 10 times more) which may be toxic to plant roots. This phase supplies O2and thereby prevents CO2 toxicity.
