Ridge roughness or K factor â WEQ is 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. See Wind erosion equation (WEQ).
