4.3.2. Subsurface Drip

Try these first

1. 1.

   What is subsurface drip irrigation?

   Hint

   Think about where the water is placed in relation to the soil.

2. 2.

   Name one advantage of subsurface drip irrigation.

   Hint

   Consider the impact of water exposure to air.

3. 3.

   What is the primary advantage of subsurface drip irrigation?

   • Increases evaporation
   • Reduces weed growth
   • Requires more water

   Hint

   Consider what happens when the soil surface is kept dry.

4. 4.

   True or False: Subsurface drip irrigation can help to maximize water use efficiency.

   • True
   • False

   Hint

   Think about how water is delivered in this method.

5. 5.

   Design a subsurface drip irrigation system for a 10-acre vegetable farm, considering water availability and soil type. Specify emitter spacing and depth.

   Hint

   Refer to the soil characteristics when you decide on spacing and depth.

6. 6.

   Evaluate a failed subsurface drip irrigation system that resulted in waterlogging. What potential causes would you investigate?

   Hint

   Consider what might not align with the ideal management practices.
