Modeling relationships between water table depth and peat soil carbon loss in Southeast Asian plantations

Environmental Research Letters, 2015
Plantation-associated drainage of Southeast Asian peatlands has accelerated in recent years. Draining exposes the upper peat layer to oxygen, leading to elevated decomposition rates and net soil carbon losses.

Vegetation and Precipitation Patterns Define Annual Dynamics of CO₂ Efflux from Soil and Its Components

Land
Respiration of soil heterotrophs—mainly of bacteria and fungi—is a substantial part of carbon balance in terrestrial ecosystems, which tie up organic matter decomposition with the rise of atmospheric CO2 concentration.

Soil respiration of four forests along elevation gradient in northern subtropical China

Ecology and Evolution, 2019
Background and aims Soil respiration is the second‐largest terrestrial carbon (C) flux, and soil temperature and soil moisture are the main drivers of temporal variation in soil respiration and its components. Here, we quantified the contribution of soil

Soil respiration in a northeastern US temperate forest: a 22‐year synthesis [PDF]

, 2013
To better understand how forest management, phenology, vegetation type, and actual and simulated climatic change affect seasonal and inter‐annual variations in soil respiration (Rs), we analyzed more than 100,000 individual measurements of soil ...

No-tillage with total green manure mulching reduces soil respiration by regulating soil moisture affecting heterotrophic respiration

Abstract Background and aims Green manure is widely used in agricultural production due to its beneficial soil modification and fertilization functions. However, the mechanisms related to the effects of green manure return methods on soil respiration (Rs) and its components are not clear.

Lack of increased availability of root-derived C may explain the low N2O emission from low N-urine patches [PDF]

, 2006
Urine deposition on grassland causes significant N2O losses, which in some cases may result from increased denitrification stimulated by labile compounds released from scorched plant roots.

Forest soil respiration showed a saturation threshold in response to increasing nitrogen deposition: Evidence from a mesocosm experiment

Geoderma
Whether there is a N saturation threshold for the response of soil respiration (Rs) to increasing nitrogen (N) deposition remains unclear in forest ecosystems. In this work, a simulated N deposition experiment involving five levels of N addition (0 to 44.

On the tree-root-soil-continuum - temporal and spatial coupling of the belowground carbon flux [PDF]

, 2007
The direct flux of current assimilates from the tree canopy to the belowground compartment drives roughly half of the soil respiratory activity in boreal forests.
