Figure 1 Soil organic carbon, total nitrogen, total phosphorus
and C:N ratio in grassland and cropland. The different lower letter
represent a significant differences between grassland and cropland at
same soil layers.
Figure 2 Relative abundance
of bacteria (A) and fungi (B), F:B ratio (C) and relative abundances of
soil dominant PLFA types (D) after grassland converted to cropland. *P < 0.05; ** P <0.01; *** P< 0.001; n.s.: not significant (P > 0.05)
