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