16.6.2. Potential Evapotranspiration (PET)

Try these first

1. 1.

   Define Potential Evapotranspiration (PET).

   Hint

   Think about what the term 'potential' suggests in this context.

2. 2.

   What does AET stand for?

   Hint

   Consider the observation of water loss in real conditions.

3. 3.

   What does PET stand for?

   • Potential Evapotranspiration
   • Plant Evapotranspiration
   • Precipitation Evapotranspiration

   Hint

   Think about what potentials mean in this context.

4. 4.

   True or False: AET is always higher than PET.

   • True
   • False

   Hint

   Consider real versus theoretical outcomes.

5. 5.

   A farmer estimated that the PET for a certain crop is 10 mm/day and the AET is only 5 mm/day during the growing season. What strategies can the farmer implement to ensure crop health?

   Hint

   Consider the gap between potential and actual water availability.

6. 6.

   Explain how temperature fluctuations might affect both PET and AET during the growing season.

   Hint

   Think about the balance between heat and moisture.
