Abstract:
1. An apparatus for determining soil water content and bulk electrical conductivity, the apparatus comprising a time domain-based device, either time domain reflectometry (TDR) or time domain transmission (TDT), the apparatus comprising: a) a hollow, substantially cylindrical tube comprising an exterior and interior surface with upper and lower ends, said tube constructed at least in part from a non-conductive material; b) at least two electrodes mounted longitudinally onto said exterior surface of said tube, one of said electrodes adapted to transmit an electronic pulse therethrough and designated a voltage electrode, and the other electrode(s) comprising ground electrodes, the electrodes being in communication with a TDR or TDT circuit; c) an electronic pulse generator in communication with said voltage electrode effective for transmitting an electronic pulse therethrough; d) a voltage receiver in communication with said voltage electrode effective for receiving a reflected pulse therefrom.
