37.11. Root Zone Depth and Soil Moisture Depletion

Try these first

1. 1.

   What is root zone depth?

   Hint

   Think about how deep roots grow.

2. 2.

   Why is monitoring soil moisture levels important?

   Hint

   Consider the impact of dry soil on plants.

3. 3.

   What is the root zone depth for cotton?

   • 0.2-0.3 m
   • 1.5-2.0 m
   • 1.2-1.5 m

   Hint

   Remember the depth ranges for different crops.

4. 4.

   True or False: Overwatering crops can lead to decreased yield due to root diseases.

   • True
   • False

   Hint

   Think about how too much water affects plants.

5. 5.

   A farmer has paddy and wheat growing together. If the paddy's root zone depth is 0.3 m and wheat's is 1.2 m, how would you recommend managing irrigation for them?

   Hint

   Consider the differences in root systems and water needs between both crops.

6. 6.

   Evaluate the potential consequences if a farmer waters a field of cotton without checking soil moisture levels and how that could affect their yield.

   Hint

   Think about how plant health is affected by either too much or too little water.
