Soil Compaction: Where, How Bad, What to Do? USDA

2007-12-7 · Compaction Definitions • Soil compaction – Decrease in soil volume and porosity, or increase in soil bulk density, due to mechanical stress on soil, for example, from traffic of agricultural machinery. Compaction can also occur naturally. • Surface compaction – compaction that occurs in the surface “plow layer”

Soil compaction UMN Extension

1  · What is compaction? Soil compaction occurs when soil particles are pressed together, reducing pore space between them (Figure 1). Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density. A compacted soil has a reduced rate of both water infiltration and drainage. This happens because large pores more effectively
