   Name two types of crops and their root depths.

   Hint

   Think of common agricultural crops.

2. 2.

   What is the relationship between crop type and drainage?

3. 3.

   Which type of crop typically has a deeper root system?

   • Lettuce
   • Corn
   • Carrots

   Hint

   Think about common crops and their root depths.

4. 4.

   True or False: Shallow-rooted crops can thrive with lower water tables.

   • True
   • False

   Hint

   Consider what shallow roots can access in terms of water.

5. 5.

   Hint

   Consider separate zones with different moisture control.

6. 6.

   Evaluate how switching from wheat to a deep-rooted crop like alfalfa could impact the existing drainage system's effectiveness.

   Hint

   Think of the consequences of adaptation.
