'''Ridge roughness''' (named ''K factor'' in the [[Wind erosion equation]] ) is - according to the [[USDA]] terminology - ''"a measure of the effect of ridges made by tillage and planting implements. It is expressed as a decimal from 0.5 to 1.0. ''
''Ridges, especially those at right angles to the prevailing wind direction, absorb and deflect wind energy and trap moving [[soil]] particles."<ref>[http://www.nrcs.usda.gov/technical/NRI/1997/summary_report/glossary.html List of USDA terminology]</ref>''
