Soil electrical resistivity (ER) was measured with the Automatic Resistivity Profiling (ARP) contact sensor in two dates, in 2016, in a 9.7-ha area with different soil moisture contents. The obtained maps indicated that ER allowed delimiting the regions within the study area and pointing out differences in the movement and accumulation of water in the soil horizons. Although there is a trend of reduction in ER values with increasing soil moisture, the spatial correlation structure of ER is similar.  aSoil water content  aSolo  aUmidade do Solo  aARP system  aILPF  aResistividade elétrica do solo  aSensor de solo  aSistema ARP  aSoil sensor  aTeor de água no solo1 aPITRAT, T.1 aRABELLO, L.
