An automatic triple-ring infiltrometer was developed using a set of pre-set sensors and transducer (AP 403, AP 404, AP 405 and AP 406, RAP001 and RAP002). The aluminum probe sensors were graduated and arranged in series to monitor the rate at which water is infiltrating into the soil layer. The working principle of automatic triple-ring infiltrometer was developed using six probes with depth calibration of 1.0mm, 26.7 mm, 12.4 mm, and 12.7 mm, respectively. The result obtained showed strong agreement with a coefficient of determination R2= 0.963, indicating positive proportionality between cumulative infiltration and time taken for the water to infiltrate at different depths. The instrument has a measuring accuracy of ± 0.3mm infiltration depth. The device works effectively under biochar amended soil and other soil formations with high precision. Accurate infiltration data generated by the instrument would be applied to estimate the depth of water available to plant and predict possible agricultural drought.
