Inherent Factors Affecting Soil Infiltration - USDA
www.nrcs.usda.govMay 01, 2012 · Soil texture, or the percentage of sand, silt, and clay in a soil, is the major inherent factor affecting infiltration. Water moves more quickly through the large pores in sandy soil than it does through the small pores in clayey soil, especially if the clay is compacted and has little or no structure or aggregation.

www.senecahs.orgSoil Structure Damage Soil structure can be destroyed. A major cause of damage is driv-ing heavy equipment over wet soil. Damage is also caused by working soil when it is either too wet or too dry. Either condition leads to the clay particles clogging the pore spaces. The soil becomes compacted and very dense; and when it dries, it becomes very ...

Soil Lab - uwsp.edu
www3.uwsp.eduSoil structure refers to the tendency of soil particles to cluster together and function as soil units called aggregates. Aggregates or crumbs contain mostly clay, silt, and sand particles held together by a gel-type substance formed by organic matter. Aggregates absorb and hold water better than individual particles.
