Contrasting Depth Dependencies of Plant Root Presence and Mass Across Biomes Underscore Prolific Root‐Regolith Interactions Open
Root distributions are typically based on root mass per soil volume. This plant‐focused approach masks the biogeochemical influence of fine roots, which weigh little. We assert that centimeter‐scale root presence‐absence data from soil pro…

Does optimality partitioning theory fail for belowground traits? Insights from geophysical imaging of a drought‐release experiment in a Scots Pine forest Open
Summary We investigate the impact of a 20‐yr irrigation on root water uptake (RWU) and drought stress release in a naturally dry Scots pine forest. We use a combination of electrical resistivity tomography to image RWU, drone flights to im…
