“…In the studied soils, homogenized and the coarse organic matter removed, the BIR for the clayey texture was between 12 cm h -1 and 35.3 cm h -1 and for the very clayey texture between 4.3 cm h -1 and 14.6 cm h -1 . Aragão et al (2017) determined the equation of soil infiltration rate using a ring infiltrometer. They performed 17 consecutive readings interspersed at different times with a total duration of 65 minutes using the infiltration equation proposed by Kostiakov and obtained the basic infiltration rate (BIR) of 11.85 cm h -1 , which was classified as very high and was explained by the soil sandy texture in the study area.…”

Agriculture is the most water-demanding economic activity. Nevertheless, the monitoring of agricultural production systems can improve the soil water condition and contribute to soil conservation, as well as increase irrigation efficiency through quick and assertive decision-making. Thus, the objective of this work was to carry out a real-time evaluation of the wetting front (WF), the water infiltration rate in the soil, and to verify whether the system performance can affect infiltration test data in a Red Latosol with clayey and very clayey textures. The public domain prototype system consisted of a permeameter, and 10 soil moisture sensors that were calibrated by the oven drying method and inserted into a PVC pipe from 10 cm to 100 cm depth. The equipment allowed the evaluation of the wetting front and calculation of the infiltration rate and water retention and variations along the soil profile. Data were analyzed using descriptive statistics using RStudio and Excel. The results showed that the prototype system is effective to simulate the water infiltration rate in the two soil textures analyzed at low cost.
