Soil microbial community structure and catabolic activity are significantly degenerated in successive rotations of Chinese fir plantations

Abstract This study examined the hypotheses that soil microbial community composition and catabolic activity would significantly degenerated by consecutive monoculture in Chinese fir plantations. The phospholipid fatty acids (PLFA) and community level physiological profiles (CLPP) methods were used...
