The moisture response of soil heterotrophic respiration: interaction with soil properties [PDF]

Biogeosciences, 2012
Soil moisture is of primary importance for predicting the evolution of soil carbon stocks and fluxes, both because it strongly controls organic matter decomposition and because it is predicted to change at global scales in the following decades. However,

Soil Heterotrophic Respiration Potential and Maximum Respiration Rate of Differently Managed Meadows [PDF]

Soil and Water Research, 2006
In this study were compared heterotrophic respiratory potential (VDS/VMAX) expressing an increase in C mineralisation rate after drying and re-wetting the soil to 60% soil water content (v/w)(VDS) in relation to maximum respiration rate (VMAX) after ...

An overlooked mechanism underlying the attenuated temperature response of soil heterotrophic respiration. [PDF]

J R Soc Interface, 2022
Biogeochemical reactions occurring in soil pore space underpin gaseous emissions measured at macroscopic scales but are difficult to quantify due to their complexity and heterogeneity. We develop a volumetric-average method to calculate aerobic respiration rates analytically from soil with microscopic soil structure represented explicitly.

Empirical estimates of regional carbon budgets imply reduced global soil heterotrophic respiration. [PDF]

Natl Sci Rev, 2021
Abstract Resolving regional carbon budgets is critical for informing land-based mitigation policy. For nine regions covering nearly the whole globe, we collected inventory estimates of carbon-stock changes complemented by satellite estimates of biomass changes where inventory data are missing.

Spatiotemporal dynamics and influencing factors of soil heterotrophic respiration in northeast China. [PDF]

PLoS One
Soil heterotrophic respiration (Rh) represents a primary pathway of carbon release from soil. Using meteorological data, DEM, soil organic carbon density, and other data, we simulated the Rh in Northeast China from 2001 to 2020 using the GSMSR model. We then analyzed its spatialtemporal distribution pattern and examined its spatial-temporal aggregation,

Responses of soil heterotrophic respiration and microbial biomass to organic and conventional production systems

Frontiers in Soil Science, 2022
The effects of organic and conventional production systems on crop productivity have been greatly explored, but their effects on soil microbial processes were often neglected.

Short-term effect of adding nitrogen in forest soil of an urban rainforest

Sustentabilidade em Debate, 2020
The deposition of atmospheric nitrogen has been increased in urban forest ecosystems, yet it is not clear how this increase affects soil respiration in the short term.

Moso bamboo expansion decreased soil heterotrophic respiration but increased arbuscular mycorrhizal mycelial respiration in a subtropical broadleaved forest

Forest Ecosystems, 2023
Moso bamboo (Phyllostachys Pubescens) expansion into adjacent forests has been widely reported to affect plant diversity and its association with mycorrhizal fungi in subtropical China, which will likely have significant impacts on soil respiration ...

Evaluating two soil carbon models within the global land surface model JSBACH using surface and spaceborne observations of atmospheric CO₂ [PDF]

, 2020
The trajectories of soil carbon (C) in the changing climate are of utmost importance, as soil carbon is a substantial carbon storage with a large potential to impact the atmospheric carbon dioxide (CO2) burden.
