1/  The Soil Erodibility Factor Kf is used in the Revised Universal Soil Loss Equation (RUSLE) and indicates
    the susceptibility of the fine-earth fraction of the soil to sheet and rill erosion by rainfall.  Rocks
    and rock fragments in the soil profile are not considered.  Values for Kf range from .10 to .64.  The
    higher the value, the more susceptible the soil is to sheet and rill erosion by rainfall.

2/  The Soil Loss Tolerance (T)value is an estimate of the maximum average annual rate of soil erosion by
    wind or water that can occur without affecting crop productivity over a sustained period.  Values of T
    range from 1 to 5 tons/acre/year and are based on depth of soil to bedrock and the type of bedrock.

3/  The Wind Erodibility Index I value is used in the Wind Erosion Equation (WEQ) and is based on soil
    texture and the relationship of dry soil aggregates greater than .84 mm to potential erosion rates of 0
    to 310 tons/acre/year from a wide, bare field. This value applies only to the surface layer.

Erosion factors are shown in this table as the K factor (Kf) and the T factor. Erosion factor K indicates 
the susceptibility of a soil to sheet and rill erosion by water. Factor K is one of six factors used in the 
Universal Soil Loss Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to predict the 
average annual rate of soil loss by sheet and rill erosion in tons per acre per year. The estimates are 
based primarily on percentage of silt, sand, and organic matter and on soil structure and permeability. 

Values of K range from 0.02 to 0.69. Other factors being equal, the higher the value, the more susceptible 
the soil is to sheet and rill erosion by water.

Erosion factor Kf indicates the erodibility of the fine-earth fraction, or the material less than 2 millimeters 
in size.

Erosion factor T is an estimate of the maximum average annual rate of soil erosion by wind or water that 
can occur without affecting crop productivity over a sustained period. The rate is in tons per acre per year.

Wind erodibility groups are made up of soils that have similar properties affecting their susceptibility to 
wind erosion in cultivated areas. The soils assigned to group 1 are the most susceptible to wind erosion, and 
those assigned to group 8 are the least susceptible. The groups are as follows:

1Coarse sands, sands, fine sands, and very fine sands.
2Loamy coarse sands, loamy sands, loamy fine sands, loamy very fine sands, ash material, and sapric soil material.
3Coarse sandy loams, sandy loams, fine sandy loams, and very fine sandy loams.
4LCalcareous loams, silt loams, clay loams, and silty clay loams.
4Clays, silty clays, noncalcareous clay loams, and silty clay loams that are more than 35 percent clay.
5Noncalcareous loams and silt loams that are less than 20 percent clay and sandy clay loams, sandy clays, 
   and hemic soil material.
6Noncalcareous loams and silt loams that are more than 20 percent clay and noncalcareous clay loams that 
   are less than 35 percent clay.
7Silts, noncalcareous silty clay loams that are less than 35 percent clay, and fibric soil material.
8Soils that are not subject to wind erosion because of coarse fragments on the surface or because of 
   surface wetness.
Wind erodibility index is a numerical value indicating the susceptibility of soil to wind erosion, or the 
tons per acre per year that can be expected to be lost to wind erosion. There is a close correlation between 
wind erosion and the texture of the surface layer, the size and durability of surface clods, rock fragments, 
organic matter, and a calcareous reaction. Soil moisture and frozen soil layers also influence wind erosion.
