- Tensiometer
- Moisture Sensor
- Infiltrometer
- Pan evaporimeter
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Irrigation scheduling instruments are used to determine when and how much to irrigate.
Step 2: Detailed Explanation:
Irrigation scheduling instruments include:
- Tensiometer (A): Measures soil moisture tension (matric potential).
- Moisture Sensor (B): Measures soil moisture content.
- Pan evaporimeter (D): Measures evaporation rate to estimate crop water use.
Infiltrometer (C):
This instrument is used to measure infiltration rate of water into the soil.
It is used for determining soil hydraulic properties, not for irrigation scheduling.
Thus, the infiltrometer is not an irrigation scheduling instrument.
Step 3: Final Answer:
Thus, the instrument that is not used for irrigation scheduling is the infiltrometer.
[0.5cm]
