Deep Drainage at 160 cm in Paddock 1 in 2005
Absolute values of drainage cannot be presented because of lack of
information about the soil hydraulic conductivity. Instead the graph
shows the relative amount of drainage on each day, and how it
accumulates through the season. It is not possible to be certain
about the total amount of drainage but it is likely to be of the
order of 20 to 50 mm for the season.
Hydraulic gradient at 160 cm in Paddock
1
A positive value of
hydraulic gradient indicates deep drainage is occurring. The larger
the value of the gradient, the larger the amount of deep drainage.
Soil water potential at 160 cm in Paddock 1
A
positive value indicates that the soil is saturated. A value less
than -100 indicates that very little drainage is likely to be
occurring.
