Abstract Biochar may affect the root morphology and nitrogen (N) use efficiency
(NUE) of rice at seedling stage, which has not been clearly verified until now. To
clarify it, we conducted a pot experiment regarding to two soil types (Hydragric
Anthrosol and Haplic Acrisol), two biochar application rates (0.5 wt% and 1.5 wt
%) and two rice varieties (common rice var. Xiushui134 and hybrid super rice var.
Zhongkejiayou12-6) meanwhile. Seedling NUE of common rice Xiuhui134 was
significantly increased (p < 0.05) by 78.2% in Hydragric Anthrosol and by
91.4% in Haplic Acrisol following biochar addition with 1.5 wt%. However, biochar addition… More >
