Question 1.
What does the Permanent Wilting Point (PWP) indicate?
Show hintHide hint
Think about when plants start showing signs of stress.
Question 2.
What type of soil retains water more tightly?
Show hintHide hint
Consider surface area and pore size.
3Question 3.
What does the Permanent Wilting Point signify?
- A. Highest water retention
- B. Point of plant wilting
- C. Suitable irrigation level
Show hintHide hint
Remember the effects on plants when moisture levels fall.
4Question 4.
True or False: The smaller the micropores, the easier it is for plants to access water.
- True
- False
Show hintHide hint
Reflect on the relationship between pore size and water accessibility.
Question 5.
Calculate the PWP given a soil sample retains 30% water but is at capacity. What implications does this have for irrigation scheduling?
Show hintHide hint
Consider how much moisture should ideally be present before wilting affects the plants.
Question 6.
Discuss the potential ecological impacts in a region where agricultural practices neglect the principles of PWP.
Show hintHide hint
Reflect on the balance within an ecosystem when water resources are mismanaged.
