Modelled soil organic carbon stocks and changes in the Indo-Gangetic Plains, India from 1980 to 2030

Soil carbon balance of rice-based cropping systems of the Indo-Gangetic Plains

“…Similarly, a continuous decline in SOC in Samastipur seems also unlikely. However, the model projection of an increase in SOC contents in the northern parts (Ludhiana and Karnal) by 2020 and a decline in all other parts of the IGP is similar to the results reported by Bhattacharyya et al (2007) for 2000-2030. However, in the long-term (by 2080), SOC declines at all sites in the IGP.…”

“…However, it underperforms in situations with heavy clay soils with high rainfall, causing severe anaerobic conditions, which results in overestimation of SOC content as also reported by Bhattacharyya et al (2007) and Milne et al (2008), as in Pantnagar, Barrackpore and Nadia. Soil characteristics such as high pH (Ludhiana-3), sodicity (Karnal) and salinity (Samastipur) also influence SOC dynamics, and, as these effects are not incorporated in the model, lead to poor model performance.…”

Impact of Temporal Change of Land Use and Cropping System on Some Soil Properties in Northwestern Parts of Indo-Gangetic Plain

“…The earlier studies reported that OC content was high on surface layers, which decreased with depth due to further addition of biomass in the surface layers [20][21][22] . The lower OC content in the lower layers during 2008 may be blocking of translocation of organic matter due to the formation of impervious layer below the surface having higher bulk density (1.8 g cm 3 ). Similar results were also reported by other studies [23][24][25][26] .…”

“…In Punjab, the acreage under rice and wheat crops stands at 2.6 and 3.4 m ha respectively. Some studies have shown that continuous rotation of cereal-cereal (rice-wheat) cropping system has resulted in negative impacts in organic carbon (OC) content 2 , while other studies have shown its positive impact on OC 3,4 . Cultivation of rice on light-textured soils in recent/active flood plains has resulted in lowering of the water table 5,6 , creation of hard pan in the subsoils, increase in soil organic carbon (SOC) 7 , and increase in selenium toxicity which adversely affects human as well as animal health 8,9 .…”

Modelling soil organic carbon stocks and their changes in the northeast of Spain

“…Recently, the Global Environmental Facility Soil Organic Carbon (GEFSOC) modelling system (Milne et al , 2007) linked the Century ecosystem model (Parton et al , 1988) to GIS layers to provide datasets that are spatially distributed according to the model needs (Easter et al , 2007). The GEFSOC system has been applied successfully in different regions of the world to estimate SOC stocks and changes under different land‐use and management conditions (Bhattacharyya et al , 2007; Cerri et al , 2007). However, the GEFSOC system has not yet been applied to European soils.…”
