The document describes a procedure to determine the water content of a soil sample using the oven drying method. Key steps include: (1) weighing an empty container and lid, adding a wet soil sample, and reweighing; (2) drying the sample in an oven at 110°C for 24 hours; (3) allowing the container to cool and reweighing to determine the dry mass; (4) calculating water content as a percentage based on the mass difference between wet and dry samples. The procedure is repeated for multiple samples and the average water content is reported.
