Weight reduction (primary method) Electrical characteristics (secondary method) Oven method. PRINCIPLE: The water content (w) of a soil sample is equal to the mass of water divided by the mass of solids. If the sample is heated at the same temperature, drying can be carried out much quicker. Weighing and Drying. The difference in the two weights (Loss on Drying) is then compared with either the original weight (Wet-base test) or final weight (Dry-base test) and the moisture content calculated. The weight of water is determined by the difference before and after drying the soil by oven dryng method. Steyermark, Chairman, et al.. 1953 Report on Recommended Specifications for Microchemical Apparatus. Determination of the wood moisture content by kiln drying . 31 publications.
