A globally robust relationship between water table decline, subsidence rate, and carbon release from peatlands

Communications Earth & Environment, 2022
Heterotrophic soil respiration and subsidence are enhanced by water table decline, with a meta-analysis estimating that soil respiration in drained peatlands across the globe release 645 Mt carbon per year.

Effect of sieving on ex-situ soil respiration of soils from three land use types [PDF]

, 2020
This study aims to investigate the effect of sieving on ex situ soil respiration (CO2 flux) measurements from different land use types. We collected soils (0–10 cm) from arable, grassland and woodland sites, allocated them to either sieved (4-mm mesh ...

Soil respiration in Chinese tea gardens: autotrophic and heterotrophic respiration

European Journal of Soil Science, 2018
Summary To obtain an improved understanding of the response of soil respiration ( R S ) to soil temperature and water content, we used a trenching treatment that could divide R S

Sustained large stimulation of soil heterotrophic respiration rate and its temperature sensitivity by soil warming in a cool-temperate forested peatland [PDF]

Tellus: Series B, Chemical and Physical Meteorology, 2013
We conducted a soil warming experiment in a cool-temperate forested peatland in northern Japan during the snow-free seasons of 2007–2011, to determine whether the soil warming would change the heterotrophic respiration rate and its temperature ...

Direct soil moisture controls of future global soil carbon changes: An important source of uncertainty [PDF]

, 2011
The nature of the climate–carbon cycle feedback depends critically on the response of soil carbon to climate, including changes in moisture. However, soil moisture–carbon feedback responses have not been investigated thoroughly.

Growing media constituents determine the microbial nitrogen conversions in organic growing media for horticulture [PDF]

, 2016
Vegetables and fruits are an important part of a healthy food diet, however, the eco-sustainability of the production of these can still be significantly improved.

Soil sample conservation from field to lab for heterotrophic respiration assessment

MethodsX, 2020
We evaluated (1) whether the sample transport time could lead to a significant loss of carbon through microbial respiration and to a change of measured respiration rates, which can be a problem in areas difficult to access, with a long travel time from field to laboratory; (2) whether the method used to quantify heterotrophic respiration for ...

Heterotrophic components of soil respiration in pastures and forests in southwestern Amazonia, Acre, Brazil

Revista Ambiente & Água, 2008
In this paper we present data on soil microbial biomass and heterotrophic respiration in pastures, mature and secondary forests, in order to elucidate their contribution to total CO2 flux from soil to atmosphere.

Potential net primary productivity in South America: application of a global model [PDF]

, 1991
We use a mechanistically based ecosystem simulation model to describe and analyze the spatial and temporal patterns of terrestrial net primary productivity (NPP) in South America.
