[Effects of Branches Biochar Application on Soil Physicochemical Properties of Acidified Soil in a plantation in Northern Guangxi].

This study aims to explore the effects of different biochar applications on soil physical and chemical properties in a plantation in Northern Guangxi, find the best biochar application amount, and provide scientific guidance for the efficient utilization of forest residue and soil improvement. The soil of a four-year plantation at the Huangmian forest farm in Northern Guangxi was selected as the study area, and six treatments including 0 (CK), 0.5% (T1), 1.
