Abstract

The growing aridification has posed huge challenges in the agriculture sector, and effective use of water resources is vital to timely growth of plants leaves to maintain healthy physiology, and for precision agriculture applications. This paper presents a novel and simple THz sensing technique to monitor the water content (WC) of three fresh leaves for continuously four days in the frequency range of 0.75 to 1.1 THz by determining the electromagnetic parameter. The weights of all three leaves were also measured for consecutive four days. By observing absorption coefficient, an upward trend was noticed with increasing frequency from day 1 to 4. However, absorption coefficient was found to be high on day 1 due to the presence of high WC in leaves and as days passed, the loss was evidently reduced due to the evaporation of WC in leaves. Upon close analysis, the results demonstrated a strong correlation of absorption an upward trend was noticed with increasing frequency from day 1 to 4. However, absorption coefficient was found to be high on day 1 due to the presence of high WC in leaves and as days passed, the loss was evidently reduced due to the evaporation of WC in leaves. Upon close analysis, the results demonstrated a strong correlation of absorption coefficient with WC of leaves.
