“…Data obtained by automatic imaging tools in crops revealed diurnal patterns as well, with dynamics differing between monocot and dicot crops (Kronenberg et al, 2021; Nagelmüller et al, 2018; Yates et al, 2019). Under field conditions, it remains mostly unknown if and when plants have access to soil moisture deep in the rooted profile (e.g., Maysonnave et al, 2022). Therefore, it is difficult to delineate the local, moisture‐driven seasonal plant activity by meteorological thresholds.…”

“…A more complex root distribution than the exponential one assumed in this study and related temporally varying transpiration water losses from different depths adds for complexity that is not captured by the SMAR model. Maysonnave et al (2022), for instance, found that root water uptake in forests can vary with time and depth depending on the water availability in different layers. These features can neither be reproduced by the original nor modified SMAR and makes forest sites generally challenging, in particular for simplified models.…”

“…Deep roots play a significant role for the water supply of plant ecosystems especially during dry conditions (Canadell et al, 1996) i.e. through hydraulic redistribution (see e.g., Neumann and Cardon, 2012) or increased root water uptake from deeper soil layers under drought conditions (Maysonnave et al, 2022). Furthermore, plant species influence infiltration and vertical soil moisture patterns through species dependent root distributions (e.g.…”

“…Woody plant use of water stored beneath soils in weathered bedrock has been documented as early as the beginning of the 20th century (Cannon, 1911). 'Rock moisture', or water derived from the unsaturated weathered bedrock layer, is now understood to be an essential plant water reservoir, particularly in seasonally dry regions where it sustains transpiration later into the dry season (e.g., Schwinning, 2010;Rempe and Dietrich, 2018;Rose, 2003;McCormick et al, 2021;Hahm et al, 2022Hahm et al, , 2020Ruiz et al, 2010;Maysonnave et al, 2022). It has been difficult to incorporate deeper water storage into dynamic vegetation models and Earth system models because weathered bedrock storage capacity has been historically challenging to quantify except at intensively monitored study sites.…”
