Question

    What is the basis of the electrical conductivity method for measuring soil moisture content?

    A Changes in soil temperature Correct Answer Incorrect Answer
    B Changes in electrical conductivity with changes in soil moisture Correct Answer Incorrect Answer
    C Changes in soil pH Correct Answer Incorrect Answer
    D Changes in soil texture Correct Answer Incorrect Answer

    Solution

    The electrical conductivity method is based on changes in electrical conductivity with changes in soil moisture. Gypsum blocks with two electrodes are used, and the conductivity across the electrodes is measured.
