Wireless sensor arrays for observing soil properties would be extremely useful in support of many precision agriculture, environmental monitoring, and terrestrial habitat observation applications. This effort describes the fabrication and functionality of CENS’�¡�Çs aggregate subterranean sensing stations referred to as soil pylons. The specific system described here includes the following sensing modalities: soil moisture, temperature, above-ground precipitation/irrigation rate and aqueous nitrate concentrations. This pylon is being deployed in the context of an wastewater recycling/precision agriculture application.
