Soil organic carbon (SOC) pool has been extensively studied in the carbon (C) cycling of
terrestrial ecosystems. In dryland regions, however, soil inorganic carbon (SIC) has received …

Soil inorganic carbon (SIC) is the largest pool (≈ 950 Pg of soil carbonate+ 1404 Pg of
bicarbonate in groundwater; ie, 1 Pg= 10 15 g= 1 gigaton) of the global carbon cycle at a …

Soil–atmosphere exchange significantly influences the global atmospheric abundances of
carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). These greenhouse gases …

Irrigation in arid croplands is necessary to sustain crop growth, but with increasing water
scarcity and population growth in drylands, irrigation systems may need to shift from flooding …

The long-term stability of soil inorganic carbon (SIC) and its minimum contribution towards
global C cycle has been challenged, as recent studies have showed rapid decreases in SIC …

Soil inorganic carbon (SIC) and organic carbon (SOC) are important carbon reservoirs in
terrestrial ecosystems. However, little attention was paid to SIC dynamics in cropland. We …

Understanding the changes in soil inorganic carbon (SIC) resulting from land-use change is
vital for evaluating terrestrial soil C stocks and predicting global change. However, a …

Determining changes in soil organic carbon (SOC) and inorganic carbon (SIC) stocks
following ecological restoration is important for estimating the regional carbon budget and …

The soil carbon reservoir is the largest carbon reservoir in terrestrial ecosystems and
consists of soil organic and inorganic carbon stocks. Previous studies have mainly focused …

Soil is a key carbon reservoir balancing global carbon budget and regulating climate
change. Barren soils in karst zones have weak capacity for soil and water conservation and …
