";s:4:"text";s:2261:" 04.SOIL MOISTURE MEASUREMENT Soil moisture is estimated both by direct and indirect method. The flow of electricity in the soil is largely electrolytic, determined by the transport of ions dissolved in moisture. They are either stationary at ... which measures changes in electrical resistance that are converted to vacuum in centibars/ kilopascals to mimic a tensiometer’s reading. Learn basic principles you need to know before deciding how to measure it. An awareness of soil resistivity at the determined location and how it varies with various factors such as temperature, depth, moisture content etc. Soil Resistivity Definition: The measure of the resistance offered by the soil in the flow of electricity, is called the soil resistivity. 1). So, in this case we know: A = 3 meters, and R = 100 ohms The resistivity of the soil depends on the various factors likes soil composition, moisture, temperature, etc.
