8. Methods of Water Application

Try these first

1. 1.

   What is surface irrigation?

   Hint

   Think about how water normally flows on land.

2. 2.

   Name one advantage of drip irrigation.

   Hint

   Consider where plants take up water.

3. 3.

   Which irrigation method uses pipes and emits water directly to plant roots?

   • Drip Irrigation
   • Surface Irrigation
   • Sprinkler Irrigation

   Hint

   Think about which method is most precise.

4. 4.

   True or False: Surface irrigation is the most cost-effective method, but has high water loss through runoff.

   • True
   • False

   Hint

   Remember the pros and cons of this method.

5. 5.

   A farm with various crops experiences significant water loss during irrigation. Recommend an irrigation method that minimizes water loss and justify your choice based on the crops grown.

   Hint

   Consider which crops need more precision in watering.

6. 6.

   Calculate the water savings if a field of 10 hectares uses drip irrigation, reducing water usage by 30% compared to surface irrigation that uses 120 mm. What is the new water application depth?

   Hint

   Remember to calculate the savings based on the reduction percentage.
