3Question 3.
What is effective rainfall?
- a) The total rainfall measured in a season

- True
- False
Show hintHide hint
Consider the definition of effective rainfall.
Question 5.
A field receives 120 mm of rain, with 30 mm lost to deep percolation and 25 mm lost to surface runoff. Calculate the effective rainfall and determine the irrigation requirement if the water requirement is 100 mm.
Show hintHide hint
Use the proper calculations for effective rainfall and the irrigation requirement.
Question 6.
Discuss the potential agricultural impacts if a region frequently experiences effective rainfall below the crop water requirement, particularly in drought conditions.
