1. Gravimetric method

    This consists of obtaining a moist sample, drying it in an oven at 105°C until it loses no more weight and then determining the percentage of moisture. The gravimetric method is time-consuming and involves laborious processes of sampling, weighing and drying in the laboratory.

    Advantages

    • Ensures accurate measurements
    • Not dependent on salinity and soil type
    • Easy to calculate

    Disadvantages
    • Destructive test
    • Time-consuming
    • Inapplicable to automatic control
    • Must know dry bulk density and to transform data to volume moisture content
