2.1.1. Natural Sub-surface Irrigation

Try these first

1. 1.

   What is natural sub-surface irrigation?

   Hint

   Think about how moisture can naturally travel through soil.

2. 2.

   Name one advantage of natural sub-surface irrigation.

   Hint

   Consider how water loss can happen in open systems.

3. 3.

   What is the primary mechanism of natural sub-surface irrigation?

   • Surface running water
   • Capillary rise
   • Drip systems

   Hint

   Focus on how water moves from below the surface.

4. 4.

   True or False: Waterlogging can be a problem in natural sub-surface irrigation.

   • True
   • False

   Hint

   Consider what happens when soil gets too wet.

5. 5.

   Evaluate the impact of climate change on high groundwater table regions reliant on natural sub-surface irrigation.

   Hint

   Consider how changing weather patterns affect water levels.

6. 6.

   Design a crop rotation plan incorporating natural sub-surface irrigation, ensuring sustainability.

   Hint

   Think about how different crops access groundwater.
