Nonetheless, data on root exudation and its spatio\u2010temporal plasticity are scarce. This study provides insights into compound\u2010specific root exudation in three temperate tree species in two seasons (late spring and late summer) and two soil compartments (forest floor and the top mineral soil), including the effect of soil chemistry. At four sites with differing mean annual temperatures and soil phosphorus levels, root exudates were sampled using an in\u00a0situ cuvette\u2010based system and analysed by gas chromatography\u2013mass spectrometry. We found seasonally and spatially varying site\u2010 and species\u2010specific exudation patterns. While the seasonal pattern was similar among species and sites, with higher exudation rates in late spring, soil compartment\u2010specific exudation depended on species and site.\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Acer pseudoplatanus<\/jats:italic>\n                    <\/jats:styled-content>\n                    tended to exude more into the mineral soil at warmer sites, while\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Picea abies<\/jats:italic>\n                    <\/jats:styled-content>\n                    exuded more in the mineral soil at all sites.
