On Drying (LOD). In an LOD test, the sample is weighed, dried, and weighed again. 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. Tests can be manually conducted (weigh, oven dry, weigh) or automated ...

Determination Of Water Content Of Soil By Oven Drying Method

The calculations of water content are done from the following equation-. The formula of calculation of water content through the oven-drying is w= (M2-M3 / M3-M1).100. Here w is water content, M 2 is the mass of the container with moist soil, M 1 is the mass of the empty container, M 3 is the mass of the container with dry soil.
