The LUCAS soil organic carbon data are measured surveyed points and the aggregated results [38] at regional level show important findings. Finally, a new proposed model for estimation of soil organic carbon in agricultural soils has estimated current top SOC stock of 17.63 Gt [39] in EU agricultural soils.
This is 3.3 times the amount of the atmospheric pool at 750 gigatons and 4.5 times the biotic pool at 560 gigatons. The pool of organic carbon, which occurs primarily in the form of SOM, accounts for approximately 1,550 gigatons of the total global carbon pool, [14] [15] with soil inorganic
In marsh areas of the Sanjiang Plain, woody encroachment was found to significantly reduce soil moisture, organic carbon, and total nitrogen. [108] [109] Shrub encroachment has led to the decline of soil quality of up to 40% in Northwest China. [110] In the Tibetan Plateau, woody encroachment is found to be one of the main grassland disturbance ...
Soils, in general, are the largest reservoirs of carbon in terrestrial ecosystems.This is also true for soils in the Arctic that are underlain by permafrost. In 2003, Tarnocai, et al. used the Northern and Mid Latitudes Soil Database to make a determination of carbon stocks in cryosols—soils containing permafrost within two meters of the soil surface. [4]
With multiple world governments looking to produce 100% carbon-free electricity, carbon capture stocks can prove to be highly lucrative investments down the road. CCS involves capturing carbon ...
Compared to natural vegetation, cropland soils are depleted in soil organic carbon (SOC). When soil is converted from natural land or semi-natural land, such as forests, woodlands, grasslands, steppes, and savannas, the SOC content in the soil reduces by about 30–40%. [78] This loss is due to harvesting, as plants contain carbon.
The rising interest in carbon capture, utilization and storage (CCUS) technologies and lifting carbon prices has created a viable environment for carbon capture stocks. CCUS technologies have been ...
Soil in boreal regions is a significant global carbon sink; boreal forest soil holds 200 Gt of carbon while boreal peatlands hold 400 Gt of carbon. Northernmost permafrost regions contain 10,355 ± 150 Pg of soil organic carbon (SOC) in the top 0-3 m and 21% of this carbon is in the soil organic layer (SOL) pool found in the top 30 cm of the ...
