Answer: Option A
Solution(By Examveda Team)
The leaf area meter determines the plant canopy of field crops.A psychrometer can be used to find relative humidity, it is computed by multiplying the amount of moisture in the air at a given temperature, dividing by the maximum amount of moisture the air could contain at that same temperature and then multiplying the quotient by 100.
The pressure plate is the instrument to measure soil water retention.
Irrometer is a meter that senses and provides a direct measurement of soil water tension.
