39.1. Delta (Δ)

Try these first

1. 1.

   What is Delta (Δ) in irrigation?

   Hint

   Think about water needs for different crops.

2. 2.

   Name one factor that affects Delta.

   Hint

   Consider what might change a plant's water needs.

3. 3.

   What is the primary role of Delta (Δ) in irrigation?

   • To define soil depth
   • To determine water requirements for crops
   • To calculate canal sizes

   Hint

   Recall what Delta represents in irrigation.

4. 4.

   True or False: Delta values are the same for all crops.

   • True
   • False

   Hint

   Think about differences between crops.

5. 5.

   You have two crops: one requiring 50 cm of water and the other requiring 150 cm. If both are grown in the same climate, what considerations should be made?

   Hint

   Think about managing water resources efficiently.

6. 6.

   Calculate the required Delta if a crop with an average water uptake of 0.8 cm/day is grown for 100 days.

   Hint

   Remember to multiply daily requirements by the base period to find the total water depth.
