Pores not filled with water are filled with soil air: a mixture of 79% nitrogen, less than 20.6% oxygen, and generally more than 0.2% carbon dioxide (CO 2) 1. The air in soil is in constant exchange with the atmosphere. Gases diffuse from the atmosphere into the soil and back out again, like breathing.
