Daily soil water changes
Figure 17—Daily Water changes
Figure 17 (Summed Graph) shows an irrigation event followed by a
staircase dynamic.
The steep part of the stairs indicates soil water change during the day light
hours (transpiration, and evaporation). Only in the first night after irrigation
can you see a sloping trend at night indicating the soil profile is still
draining. Then the nightly trend is flat indicating the soil profile has
stopped draining and there is no drainage and crop water use at night.
The big step indicates an increase of crop water use on a hot day and the
small step indicates a decrease in crop water use on a cool day.
