Systems and methods for assessing a microbial characteristic within a growing medium. Such a system assesses one or more microbial characteristics, such as biomass and/or microbial activity, within a growing medium, such as soil. Electrical properties of a microbially degradable material in contact with the growing medium are measured. The measurements are used to determine the microbial characteristic(s) based at least partly on degradation of the microbially degradable material.

System for assessing a microbial characteristic within a growing medium and associated methods

A batteryless, chipless, sensor is disclosed which includes a substrate, at least two conductive strips disposed on the substrate, a passivation layer encasing the substrate and the at least two conductive strips, wherein the conductive strips are adapted to respond to an interrogation signal from a reader having a first polarization, with a response signal at a second polarization different than the first polarization.
