WebSoil porosity refers to the space between soil particles, which consists of various amounts of water and air. Porosity depends on both soil texture and structure. ... Soils with smaller particles (silt and clay) have a larger surface area than those with larger sand particles, and a large surface area allows a soil to hold more water. WebAug 4, 2024 · The reduction in porosity by mechanical compaction continues during sediment burial, in concert with the precipitation of cements (chemical diagenesis). This is particularly evident during the compaction of mud. The high initial porosity of mud is due to micro-pores between clay particles that have dimensions measured in microns.
