Local analysis of soil root interactions. A. Evolution of transpiration rate during the three days of experiments. B. Evolution of the soil water content at different distances from the roots (0-15 cm). Red area highlight the difference in soil water content between the root and the first centimeter of soil. Grey area represent the night (no measurements). The arrow highlight the water redistribution in the soil occurring at night.
