Description: A system to monitor mass and temperature of soil samples during drying in a microwave environment is described. The drying characteristics of a clay, sandy loam and sand were observed. Mass-time and temperature-time curves indicated that the evaporation and release of water from a small volume of soil behaves according to a theoretical three-part sequence dictated by thermo dynamic principles: (1) constant temperature rise without mass loss, (2) constant mass loss without temperature rise and, (3) rising tem perature with exponentially decaying mass loss. Time to transition points and drying efficiency are discussed with respect to microwave power setting, soil type and initial moisture content.
