|Summary:||Compaction of soil can contribute to size and numbers of pores. Soil can become compacted many ways, and this can have long-term effects. For example, when American settlers traveled the Oregon Trail in their wagons in the 1800s, soil became so compacted that we still can see wheel ruts today. Try the following experiment and draw your own conclusions about compaction and pore size in soil.|
