摘要:
PurposeSoil phosphorus (P) availability and microbial community are typically affected by agricultural land use. This study aimed to explore the link of soil available P and P-cycling-related bacteria and to distinguish P mobilization strategies between upland and paddy cropping systems.Materials and methodsA total of 120 soil samples were collected from 60 sites with adjacent upland and paddy soils in subtropical China. we analyzed soil P fractions and investigated bacteria-mediated P cycling by quantifying the abundance of genes involved in organic P (Po) mineralization (phoD, phoX, phoC), i...
