Soil organic carbon across scales

Global Change Biology, 2015
AbstractMechanistic understanding of scale effects is important for interpreting the processes that control the global carbon cycle. Greater attention should be given to scale in soil organic carbon (SOC) science so that we can devise better policy to protect/enhance existing SOC stocks and ensure sustainable use of soils. Global issues such as climate

Soil salinity decreases global soil organic carbon stocks

Science of The Total Environment, 2013
Saline soils cover 3.1% (397 million hectare) of the total land area of the world. The stock of soil organic carbon (SOC) reflects the balance between carbon (C) inputs from plants, and losses through decomposition, leaching and erosion. Soil salinity decreases plant productivity and hence C inputs to the soil, but also microbial activity and therefore

Soil organic carbon dynamics jointly controlled by climate, carbon inputs, soil properties and soil carbon fractions

Global Change Biology, 2017
AbstractSoil organic carbon (SOC) dynamics are regulated by the complex interplay of climatic, edaphic and biotic conditions. However, the interrelation of SOC and these drivers and their potential connection networks are rarely assessed quantitatively.

Organic carbon and soil porosity

Australian Journal of Soil Research, 2003
The %C within the top sandy 0.15 m of a sodic Hydrosol under native trees consisted of a constant %C in uncharged organic matter and a %C in negatively charged organic matter decreasing linearly with depth, as did the specific volume of the soil. The kaolinitic clay present was strongly bonded together.

Soil Organic Carbon, Soil Formation and Soil Fertility

2013
Soil organic carbon (SOC) plays a vital role in soil formation. The accumulation of SOC is one of the initial soil forming processes and is determined by physical, chemical, biological and anthropogenic factors with complex interactions. On the other hand, SOC and its composition influences other soil forming processes like leaching of cations, soil ...

CARBONATE DETERMINATION IN ORGANIC SOILS

Canadian Journal of Soil Science, 1974
The acid neutralization method and manometric procedures, using several acid-reducing agent combinations, were compared to determine their suitability for carbonate determination in organic soils. The soil–acid reaction observed with the acid neutralization procedure was significantly influenced by the acid concentration and soil type.

Soil organic carbon distribution in roadside soils of Singapore

Chemosphere, 2016
Soil is the largest pool of organic carbon in terrestrial systems and plays a key role in carbon cycle. Global population living in urban areas are increasing substantially; however, the effects of urbanization on soil carbon storage and distribution are largely unknown.

Global soil organic carbon assessment

Global Food Security, 2015
Soil carbon is a key component of functional ecosystems and crucial for food, soil, water and energy security. Climate change and altered land-use are having a great impact on soils. The influence of these factors creates a dynamic feedback between soil and the environment.

Soil Organic Matter and Soil Organic Carbon in Barito Delta

Sustainability (STPP) Theory, Practice and Policy, 2023
Soil organic matter and soil organic carbon is essential indication of soil carbon stock in terrestrial ecosystem particularly in peatland. Spatial distribution of soil organic carbon and soil organic matter is primary assessment to predict future soil condition under climate change traits.

Soil organic matter to soil organic carbon ratios of peatland soil substrates

Geoderma, 2014
Abstract Data of soil organic matter (SOM) content can be used for the assessment of stocks and changes of soil organic carbon (SOC) in peatland soils. Therefore, it is essentially necessary to convert SOM contents into SOC contents by SOM/SOC ratios (“conversion factors”).
