39.6. Methods to Improve Duty

Try these first

1. 1.

   What is the purpose of lining irrigation canals?

   Hint

   Think about water conservation.

2. 2.

   What is one benefit of using drip irrigation?

   Hint

   Consider how water is applied to the plants.

3. 3.

   What is the main goal of lining canals?

   • To increase evaporation
   • To reduce seepage
   • To increase soil salinity

   Hint

   Think about how water can be lost in a canal system.

4. 4.

   True or False: Drip irrigation is less efficient than traditional methods.

   • True
   • False

   Hint

   Consider how water delivery impacts plant health.

5. 5.

   Considering a field where irrigation duty is low, discuss the consequences for crop yield and suggest how to improve it using the methods discussed in this section.

   Hint

   Think about each method's direct impact on water efficiency and crop health.

6. 6.

   You have a canal system where seepage rates are high. Design a plan using at least three methods to improve duty and justify your choices.

   Hint

   Consider how each improvement directly relates to the concepts discussed.
