要旨本文	This study investigated the effect of soil ameliorants on the root development of two-year-old Zelkova serrata under compacted soil conditions. Pot experiments included four treatments: control (compaction), ameliorant 1 (compaction + biochar), ameliorant 2 (compaction + organic fertilizer) and uncompacted soil. Soil physicochemical properties (bulk density, porosity, permeability, pH, total carbon, nitrogen) and root morphological traits (length, surface area, volume, root tissue density) were analyzed. While the soil ameliorants significantly improved soil properties, they did not affect the root traits. Coarse roots (>2mm) showed no significant correlations with soil properties. In contrast, fine roots (≤2mm) traits were positively correlated with soil permeability, suggesting that improved soil structure may enhance fine root development.
