Abstract: The quantity of water present in soils is usually expressed as a percentage of the dry weight of the soil and is known as water content. Typically, water contents are determined by drying moist soils to a constant weight in a 110 ± 5 C° oven for 4 to 16+ hr, depending upon soil type. While this method is simple and accurate, it is slow and occasions often arise when more rapid drying methods are desired. Microwave energy offers a rapid alternative method. However, the amount of microwave energy absorbed is directly proportional to the exposure time, and thus certain precautions are required. This report describes a method of using microwave energy for rapidly determining water contents within 0.5 or less percentage points of those determined by using conventional ovens.
