• Divergent rhizosphere microbial necromass dynamics between two plant species in response to water addition in a semi-arid region (2026) · doi

  Abstract Microbial necromass carbon influences soil organic carbon (SOC) persistence, yet its response to soil moisture change in semi-arid rhizospheres remains unclear.

• Soil Respiration Response to Simulated Precipitation Change Depends on Ecosystem Type and Study Duration (2022) · doi

  Abstract Soil respiration—the flow of biologically‐generated CO 2 from the soil surface to the atmosphere—is a major component of global carbon cycling, but the long‐term response of this flux to altered precipitation regimes remains uncertain, due to different responses of soil respiration in distinct ecosystems with varying degrees of water limitation.

• The response of microbial necromass C and its contribution to SOC to vinasse biochar based on a pot experiment (2026) · doi

  Introduction Microbial necromass carbon (MNC) is a cornerstone of stable soil organic carbon (SOC), yet how biochar amendments impact its dynamics over time remains poorly understood.

• Dynamics of soil organic carbon and nitrogen following agricultural abandonment in a karst region (2017) · doi

  Abstract Agricultural abandonment is regarded as a major driver of soil organic carbon (C) dynamics, but the mechanisms underlying the direction and magnitude of soil C dynamics following agricultural abandonment are poorly understood.
