Different treatments of logging residues can impact on the forest soil carbon pool, but the short-term effects are still unclear. This study aimed to the relationship between the changes of the addition of logging residues and different tree species soil organic carbon content and basic soil parameters. The experimental site was located in Harbin, China, and four logging residue addition levels were set under six forest types, converted to carbon added as 0, 250 (low carbon addition, LC), 500 (medium carbon addition, MC) and 1000 (high carbon addition, HC) g/m2. In the short-term (five months), the logging residues partially decomposed, but the effect on basic soil parameters was small. Soil organic carbon, microbial carbon, and dissolved organic carbon increased significantly in the 0–10 cm soil layer for some tree species, and not significantly in the 10 –20 cm soil layer. There is no consistent relationship between the addition of logging residues and soil parameters under different tree species. That adding logging residues could increase soil carbon pool, there were treespeciesspecific differences in the dynamics of soil processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
