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."[1]
