Soil organic carbon dynamics and its influence on the soil erodibility factor
agrotechnical erosion control measures soil erodibility factor soil erosion soil organic carbon
2015/3/5
The effect of erosion and erosion control measures on changes in the amount of organic matter in soil was studied. We investigated the influence of organic matter inputs into the soil on surface runof...
Nitrogen, Phosphorus and Carbon Dynamics during Storms in a Glaciated Third-Order Watershed in the US Midwest
DOC nitrate phosphorus hydrology
2015/1/16
The characterization of the nutrients nitrogen, phosphorus and carbon (NPC) export to streams during storms is an integral part of understanding processes affecting water quality. Despite the fact tha...
Long residence times of rapidly decomposable soil organic matter: application of a multi-phase, multi-component, and vertically resolved model (BAMS1) to soil carbon dynamics
Long residence times rapidly decomposable soil organic matter multi-phase multi-component vertically resolved model soil carbon dynamics
2014/12/19
Accurate representation of soil organic matter (SOM) dynamics in Earth system models is critical for future climate prediction, yet large uncertainties exist regarding how, and to what extent, the sui...

Soil organic carbon (SOC) plays a vital role in determining soil fertility, water holding capacity and susceptibility to land degradation. On the Chinese Loess Plateau, a large amount of crop residues...
Dissolved organic carbon and its carbon isotope compositions in hill slope soils of the karst area of southwest China: Implications for carbon dynamics in limestone soil
karst slope land soil organic carbon dissolved organic carbon δ13C
2017/4/11
Dissolved organic carbon (DOC) can be considered fine indicators of soil quality that influence soil function in specific
ways and are very sensitive to changes in soil management practices. In this ...
Organic carbon dynamics and enzyme activities in agricultural soils amended with biogas slurry, liquid manure and sewage sludge
Biogas Slurry Organic Wastes Organic Carbon Dynamics
2013/2/27
The application of organic soil amendments is a common practice for increasing soil fertility and soil organic carbon (SOC) content. In recent years, a new product from biogas production, biogas slurr...
Carbon dynamics and community production in the Mississippi River plume
Carbon dynamics community production Mississippi River plume
2014/4/2
Dissolved inorganic carbon (DIC), total alkalinity (TAlk), pH, and dissolved oxygen (DO) were determined in the Mississippi River plume during five cruises conducted in the spring, summer, and fall. I...
Carbon Dynamics in Tallgrass Prairie and Wheat Ecosystems
Soil carbon carbon pools mineralizable carbon microbial biomass carbon recalcitrant carbon
2009/1/13
Soil carbon (C) dynamics is an important aspect of the global C cycle. Soils can be a sink or source for atmospheric CO2 depending upon management. Tallgrass prairie and wheat (Triticum aestivum L.) a...
