Biochar-Based Fertilizer Decreased Soil N2O Emission and Increased Soil CH4 Uptake in a Subtropical Typical Bamboo Plantation

Soil is a crucial contributor to greenhouse gas (GHG) emissions from terrestrial ecosystems the atmosphere. The reduction of GHG in plantation management combating and mitigating global climate change. A 12-month field trial was conducted explore effects different fertilization treatments (control, without fertilizer (CK); biochar-based treatment (BFT); chemical (CFT); mixture 50% BFT CFT (MFT)) on soil typical bamboo (Pleioblastus amarus (Keng) Keng f.) plantation. results demonstrated that compared with CK, reduced annual cumulative N2O emission by 16.3% (p < 0.01), while MFT significantly increased it 31.0% 23.3% respectively. Meanwhile, CH4 uptake 5.8% 0.01) 7.5% respectively, there no statistically significant difference between control. In addition, BFT, CFT, CO2 9.4% 0.05), 13.0% 26.5% 0.01). warming potential (GWP) did not change significantly, GWP 13.7% 0.05) 28.6% Structural equation modeling revealed affected changing labile carbon nitrogen pools. This study suggests utilizing new ideas strategies for soils subtropical Pleioblastus plantations.
