...Back in 2010...
Aquifer level
dropped ~60 ft.

~750 residential
wells were impacted

11 days of freezes
Materials and Methods
...How did you do it?
Results
...What
happened??
> 140 sinkholes
reported

No yield differences!
Can you reduce the
amount of water
in irrigation and
still protect the
plants from cold
damages?
Maybe less water can still protect the plants...
...It's believed to be caused by
Hypothesis
Project
Location:

Plant Science and Research Education Unit, near Citra, FL
If we reduce the pressure in the irrigation system, what will happen to the strawberries?
