Figure 22—Depth of irrigation balances soil moisture extraction
Figure 22 shows the same site as Figures 20 and 21. Here the depth of
irrigation replaces the amount of soil water extraction at the bottom of the
root zone at the same magnitude as it was removed by the plant.
A slight
hump
in soil water increase and not the sharp peak of water
drainage from this layer indicates the optimal depth of irrigation.
If you manage to reproduce, on your
Irrigation Management Chart
,
the
trends shown on Figure 22, then you have found the depth of irrigation that
constitutes the Full Point
.
