Changes in soil microbial biomasses and their quotients over the succession of karst rocky desertification [PDF]

Proceedings of the 3rd International Conference on Advances in Energy and Environmental Science 2015, 2015
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.
