1. Soil Science One A Post Lab Discussion

2. What is pore space?

3. "Soil porosity" refers to the amount of pore, or open space between soil particles. Pore spaces may be formed due to the movement of roots, worms, and insects; expanding gases trapped within these spaces by groundwater; and/or the dissolution of the soil parent material. Soil texture can also affect soil porosity.

4. Pore Space (Question Three)—Why Important?

5. Pore Space in Soil Importance Soil porosity concerns the oxygen found within these pore spaces. All plants need oxygen for respiration.
