Question 2.
Why is soil moisture important in field experimental plots?
Show hintHide hint
Think of it as tracking available water.
3Question 3.
What is the main purpose of field experimental plots?
- To provide data for models
- To grow crops without irrigation
- To test soil types
Show hintHide hint

4Question 4.
True or False: Evapotranspiration includes only evaporation from soil.
- True
- False
Show hintHide hint
Consider what transpiration adds to the definition.
Question 5.
In a field experimental plot, you applied 300 mm of water. Over four weeks, 50 mm evaporated, 30 mm was absorbed by plants, and 20 mm ran off. What is the estimated ET?
Show hintHide hint
Use the water balance to find remaining water.
Question 6.
Discuss how changes in climate might affect measurements and results from field experimental plots.
Show hintHide hint
