Abstract
A calibration equation describing the relationship between electrical resistance and gravimetric soil moisture was generated for resistance-type soil-moisture-sensing units to be used in a high-clay-content soil. Soil moisture percentages measured gravimetrically and percentages predicted by entering resistance values from a validation set of moisture-sensing units into the equation did not differ. Subsequent analyses indicated that with a calibration set of five soil moisture units, a reliable equation could be generated with data from as few as three wetting-drying cycles in a high-clay-content soil.This publication has 1 reference indexed in Scilit:
