Abstract. Quantifying the impact of biochar on carbon persistence across soil textures is complex, owing to variability in conditions. Using artificial soils with precise textural and mineral composition, we could disentangle effects from particle size. We can show that application significantly reduces early-stage mineralization rates plant residues various (from 5 41 % clay) but more sandy soils. This finding suggests compensate for lack clay promoting C systems. short report contributes understanding texture interactions.
