Abstract
Abstract Extreme droughts are becoming more frequent and strongly affect ecosystem productivity, yet their impact on belowground productivity—key to the carbon cycle—remain underexplored. Using a coordinated drought experiment across six Eurasian grassland sites spanning a precipitation gradient, we found that extreme drought had little effect on belowground net primary productivity (BNPP) or root biomass across the 0-20 cm soil profile because drought-induced shifts in root allocation compensated across soil depths. Specifically, drought induced site- and depth-specific shifts: in xeric grasslands, BNPP and root biomass increased in the 0-10 cm layer but declined in the 10-20 cm layer, whereas mesic grasslands exhibited the opposite pattern. These contrasting responses were consistent with shifts in depth-specific soil moisture. Consequently, the apparent resistance of belowground productivity to drought masks a redistribution of root growth along the vertical soil profile. Accounting for such depth-dependent root dynamics is essential for understanding ecosystem functioning, including carbon cycling, plant persistence, and ecosystem responses to intensifying climate extremes.
