An investigation was made to develop a microwave drying system that will determine soil-water contents that are equivalent to those obtained in a conventional oven maintained at 110 plus or minus 5 deg C safely, reliably, and quickly. The drying system is based on computer control of microwave energy applied to a soil specimen with continuious monitoring of its mass. The equipment is capable of determining the water content of almost any inorganic to slightly organic soil within a time frame of about 15 min using a microwave power source that outputs about 700 watts. The system is user friendly, free from operator influence, and requires no attention after test initiation.
