Abstract:To evaluate soil fertility of karst land undergoing rocky desertification (RD), the changing trend of soil microbial biomass properties over the succession of RD were studied by investigating the stands and analyzing the soil samples with four different RD grades in the northwestern Hunan province, China. The results showed that the changing trend of microbial biomass C (MBC), microbial biomass N (MBN), microbial biomass P (MBP), and the microbial biomass quotients including the ratio of MBC to total organic C… Show more
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.
