Land use effects on soil microbiome composition and traits with consequences for soil carbon cycling.

ABSTRACT: The soil microbiome determines the fate of plant-fixed carbon. The shifts in soil properties caused by land use change leads to modifications in microbiome function, resulting in either loss or gain of soil organic carbon (SOC). Soil pH is the primary factor regulating microbiome characteristics leading to distinct pathways of microbial carbon cycling, but the underlying mechanisms remain understudied. Here, the taxa-trait relationships behind the variable fate of SOC were investigated using metaproteomics, metabarcoding, and a ¹³C-labeled litter decomposition experiment across two temperate sites with differing soil pH each with a paired land use intensity contrast. ¹³C incorporation into microbial biomass increased with land use intensification in low-pH soil but de
