The types of subsurface
drainage that is represented are those that are deep drained by tiles or by
deep lateral ditches.
Main effect is how drainage
system affects runoff, which is represented by inputting values for two
hydrologic soil groups, one when no drainage system is present and the other
is when the a highly efficient system is used.
The fraction of the area
relates to the fraction of the area where the soil loss is being computed
that is treated with the drainage system. For example, a low value for the
fraction drained would be entered where only wet spots are drained.
