Solution(By Examveda Team)
A leaf area meter is a lightweight instrument to get leaf area measurements. It is widely used to measure crop canopy.A psychrometer is an instrument that measures relative humidity in the atmosphere by taking two thermometers i.e. both a wet bulb and a dry bulb to take a temperature reading.
The pressure plate is the device that is used to determine soil moisture, water retention and suctions greater than 0.4 bar.
Irrometer is the instrument use to measure Atmospheric tension. An Irrometer will measure the actual soil water tension, true measurement of soil water potential also.
