Soil organic matter (SOM) is essential for nutrient cycling and soil carbon (C) accumu-lation, both of which are heavily influenced by the quality quantity plant litter. Since SOM dynamics in relation to diversity poorly understood we investigated effects willow variety mixture, site on C stocks, chemical composition ther-mal stability. Using pyrolysis-field ionization mass spectrometry analysed top 10 cm from two 7-year-old experimental sites Germany Sweden, with monocultures mixtures varieties (Salix spp.) belonging different species. Overall, had strongest effect quality. Results showed significant variability across identity mixture accumulation chemistry. In German (Ros-tock), yearly was higher (p &lt; 0.05) ‘Loden’ (1.0 Mg ha-1 year-1) compared ‘Tora’ (0.5 year-1), whilst Swedish (Uppsala), ex-hibited similar rates around 0.6 year-1. Willow significantly affected at sites, while mixing minor effects. Our findings emphasize significance site-specific context or species shaping plantations.
