44.9.1. Sample Irrigation Scheduling Chart

Try these first

1. 1.

   Define 'Crop Stage' in the context of irrigation.

   Hint

   Think about the stages of plant growth.

2. 2.

   What is Evapotranspiration (ET)?

   Hint

   It combines two processes in water loss.

3. 3.

   What does the term 'Irrigation Interval' refer to?

   • The amount of water actually used
   • The time gap between irrigation events
   • The depth of water applied

   Hint

   Consider how often plants need water.

4. 4.

   True or False: Understanding soil moisture status is unimportant in irrigation scheduling.

   • True
   • False

   Hint

   It indicates the water needs of plants.

5. 5.

   A farmer finds their crop requires an irrigation interval of 7 days due to high ET rates. After heavy rainfall, the moisture level rises substantially. How should the farmer adjust their schedule?

   Hint

   Consider the recent weather changes and their effects.

6. 6.

   You need to irrigate a vineyard with a root zone depth of 45 cm. If the current moisture content is 10 cm and moisture depletion is 25%, what is the depth of irrigation needed?

   Hint

   Calculate the maximum depletion first before incorporating the current moisture.
