World Health Organization estimates that one in eight person die from air pollution.The main objective of our study is to analyze the feasibility of genetically engineered plants to remove polluting volatile compounds from air.In this work we focused on understanding the impact of soil composition (e.g., clay content) as RF waves travel underground.

In the second part of our experiment, we used regular gardening soil mostly composed of organic matter, perlite and vermiculite.

Vermiculite keeps the soil hydrated and is part of the clay minerals group. In both cases, we maintained the temperature at 23 degrees Celsius.

We measured the RF signal path loss through the sand for the above frequencies at different horizontal distances between the transmitter and receiver.

We also measured RF signal strength as we changed the vertical distances between the two antennas.

Therefore, soil monitoring and understanding changes in soil ecosystem are considered to be important aspects of any environmental monitoring.

The recent emergence of Wireless Biosensor Networks (WBNs) promises addressing many ecological questions, particularly related to soil, though providing uninterrupted real-time data from various biosensors using RF signals.

On the other hand, the path loss in sand is about 0.9-1.2 d B more than air.

It is therefore, preferred to use lower band frequencies for underground biosensors.

Our research focused on 5.0, 2.5, and 0.9 GHz ISM bands.

The first part of our experiment was conducted in a 103-gallon weathertight trunk container filled with sand, mostly composed of silica in the form of quartz, with no clay.
