The bulk of gaseous interchange in soils takes place by _____.

Question

Quizplus · Accepted Answer

Gaseous interchange in soils primarily takes place by diffusion, which is the movement of gases from areas of high concentration to areas of low concentration. Mass flow and dissolution in water contribute to some degree, but diffusion is the main mode of gaseous exchange in soils. The partial pressure of N₂ is not a relevant factor in gaseous interchange in soils. Respiration, while important for the living organisms in the soil, is not a mode of gaseous interchange in soils as it does not involve the movement of gases between the soil and the atmosphere.
