ABSTRACT = {Intensive practices in forest soils result in dramatic nitrogen (N) losses, particularly ammonia (NH<sub>3</sub>) volatilization, to adjacent environmental areas. A soil column experiment was conducted to evaluate the effect of bamboo biochar on NH<sub>3</sub> volatilization from tea garden and bamboo forest soils. The results showed that biochar amendment effectively reduced NH<sub>3</sub> volatilization from tea garden and bamboo forest soil by 79.2% and 75.5%, respectively. The soil pH values increased by 0.53-0.61 units after biochar application. The NH<sub>4</sub><sup>+</sup>-N and total N of both soils were 13.8-29.7% and 34.0-41.9% higher under the biochar treatments than under the control treatment, respectively. In addition, the soil water contents of the two biochar-amended soils were significantly higher (<i>P</i> < 0.05), by 10.7-12.5%, than that of the soils without biochar amendment. Therefore, biochar mitigates NH<sub>3</sub> volatilization from the tested forest soils, which was due to the increases in soil NH<sub>4</sub><sup>+</sup>-N, total N and water contents after biochar amendment. Our main findings suggest that biochar addition is an effective management option for sustainable forest management.},
