Soil Texture and Compaction | SportsField Management

Jun 16, 2020· The relationship between soil compaction, soil texture and root growth is shown in Table 2. This illustrates that one of the benefits of having a sandy texture is that there is still pore space when the soil is somewhat compacted. Soils with finer textures have little pore space when compacted, and root growth suffers at lower bulk densities.

Soil compaction | UMN Extension

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 move water downward through ...
