The adjacent table lists the
default species factor (Ks)
and root depth values used
to calculate the irrigation
schedule. If you do not want
to use the default values then
use the Custom Plant Factor
method.
The plant choices and their
respective Ks values listed in
the table are representative
of different plant varieties
that fall into these broad
categories.
For example: a low water need shrub would use 20% of ETo and have
a default root depth of 8 inches.
