Erosion
Accelerated Erosion
erosion caused by human disturbances, such as roads, buildings, and traffic, it is often 10 to
1000 times as destructive as geological erosion (natural erosion).

Soil is washed or blown away faster than new soil can be formed.
Cropland erosion
12-7 Mg/ha by water

5 Mg/ha by wind
Prediction of erosion

A=RKLSCP

R= approximately 140 for ConAgra site

R=rainfall factor, total product of the kinetic energy of the storm times the maximum 30-minute
intensity of fall and modified by any influence of snowmelt

K=0.43

K= soil erodibilty factor

LS=? (p103-104)

LS=slope length and slope gradient factors

C=cropping management factor

P=the erosion control practice factor

Continuous bluegrass has about 1 ton/acre soil loss (annually-?), p.105
