CARBONATE DETERMINATION IN ORGANIC SOILS
Canadian Journal of Soil Science, 1974The 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 and soil organic carbon redistribution on the landscape
Geomorphology, 2007Patterns of soil organic carbon (SOC) vary widely across the landscape leading to large uncertainties in the SOC budget especially for agricultural landscapes where water, tillage and wind erosion redistributes soil and SOC across the landscape. It is often assumed that soil erosion results in a loss of SOC from the agricultural ecosystem but recent ...

Soil organic carbon: The value to soil properties
Journal of Soil and Water Conservation, 2013M aintaining or improving soil properties is becoming increasingly important to sustain modern agriculture under increasing demands to preserve biodiversity and environmental quality. Enhancing the inherent capacity of a soil to buffer changes against anthropogenic stresses and extreme climatic events such as droughts, intense rainstorms, heat waves ...

Carbon as a substrate for soil organisms
2005SUMMARY In many ecological studies, soil carbon is regarded as a barely differentiated whole with little attention paid to its underlying characteristics. Although it is widely appreciated that decomposer organisms are nearly infallible as degraders of organic molecules, there are marked differences in the utilisation of different components of ...

Soil organic matter to soil organic carbon ratios of peatland soil substrates
Geoderma, 2014Abstract 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”).

Soil Organic Carbon, Soil Formation and Soil Fertility
2013Soil 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 ...

Organic Carbon in Soil and the Global Carbon Cycle
1993Soil organic matter is, simultaneously, the most inert carbon cycle component of terrestrial ecosystems, and the most dynamic component of terrestrial geologic systems placing it in a pivotal position in the biogeochemistry of carbon. The large size and potentially long residence time of the soil organic matter pool make it an important component of ...
