Question 1.
What does 'evapotranspiration' refer to?
Show hintHide hint
Think about both water loss from soil and plants.
Question 2.
Define a lysimeter.
Show hintHide hint
What setup does it involve?
3Question 3.
What is the primary function of a lysimeter?
- To measure water temperature
- To calculate water loss
- To track chemical changes
Show hintHide hint
Think about how water dynamics are tracked.
4Question 4.
Direct methods provide high accuracy in measuring ET. True or False?
- True
- False
Show hintHide hint
Consider the nature of data collection.
Question 5.
You set up a lysimeter in a field and record the following data: Initial weight: 100 kg, After one week: 90 kg. Calculate the ET over that week. If water input from rainfall was 5 kg, what is the net ET?
Show hintHide hint
Weight change minus water inputs gives you the ET measure.
Question 6.
Discuss how adopting the field experimental plot method can influence irrigation practices in a given agricultural setup. Provide examples of potential changes in practice.
Show hintHide hint
Think about how informed decisions improve resource management.
