Agricultural systems are increasingly challenged of achieving high yields while optimizing plant water consumption. Soil conservation practices are preponderant in rain-fed agriculture for increasing water infiltration, water storage in the soil, and for promoting root development. This study aimed to assess the spatial-temporal soil water content t (0) dynamics identified by the application of electrical resistivity tomography (ERT) surveys in an Oxisol under grain production systems in the Brazilian Cerrado. The utilized cropping systems were: soybean monoculture (SS); maize monoculture (MM); maize/soybean rotation (MS); maize/soybean rotation with intercropped brachiaria (MBSB); maize/soybean rotation with high fertilizer investment (MS-HI), and MBSB and high fertilizer investment (MBSB-HI). ERT measurements were performed at field conditions using different time-steps during the rainy (March, 2019) and dry seasons (July 2018 and 2019). Logarithmic and power models were tested for evaluating the relationships between ? and the electrical resistivity (p). Results showed ERT was adequate for monitoring the spatial-temporal 0 variation and for inferring soil-plant related processes (i.e., water uptake and macro-porosity due to roots development). The power model was more suitable in depicting the 0 - p relationship, and for imaging the water unavailability for plants during the dry periods. Intercropped brachiaria positively affected the ? dynamics due to its aggressive root systems. MBSB-HI showed the highest 0 values in the rainy season, demonstrating that ecological intensified cropping systems can help overcome severe dry spells, in the Brazilian Cerrado.
