Reduction of quality and soil productivity due to organic carbon losses is one of the most important consequences of land use changes, that creates irreparable effects on the soil. To evaluate the land use effect on the amount of soil organic carbon in Vertisols, Sartip Abad series with extent of 1850 hectare in south of Bilehvar area in Kermanshah province was studied by using the completely r...

• Afforestation has been proposed as an effective method of carbon (C) sequestration; however, the magnitude and direction of soil carbon accumulation following afforestation and its regulation by soil nitrogen (N) dynamics are still not well understood. • We synthesized the results from 292 sites and carried out a meta-analysis to evaluate the dynamics of soil C and N stocks following afforest...

due to the notable role of different land uses in carbon sequestration and emission, four treatments including rangeland as control, haloxylon plantation area, olea plantation (olive garden), and residential lands, were selected to study the effects of land use change on soil carbon sequestration and emissions in eivanakei rangelands, semnan province. carbon stocks in vegetation and soil of eac...

For decades, conservation tillage has been promoted as a measure to increase carbon stocks in arable soils. Since organic farming improves soil quality and storage, reduced under conditions may further enhance this potential. Therefore, we assessed (SOC) of compared with mouldboard ploughing nine field trials France, Germany, the Netherlands, Switzerland same sampling analytical protocol. We sa...

organic matter and its related soil properties are among the most important indicators of soil quality. despite the importance of soil organic carbon, no comprehensive study has been done on organic carbon changes in soils of the isfahan province. the objective of this research was to investigate factors affecting soil organic carbon in soils of this province. a total of 248 surface soil sample...

Trembling aspen covers a large geographic range in North America, and previous studies reported that a better understanding of its singular influence on soil properties and processes is of high relevance for global change questions. Here we investigate the potential impact of a shift in aspen abundance on soil carbon sequestration and soil carbon stability at the continental scale by conducting...

To assess the effects of different levels of soil lead on mineralization of organic carbon and nitrogen, a factorial pot experiment was conducted using litter bag method. The factors examined were different levels of soil lead (0, 25, 50, 100, and 200 mg kg-1soil) and incubation periods (1, 2, 3 and 4 months) in three replications. At the end of incubation periods, the litter bags were pulled o...

Mangroves provide extensive ecosystem services that support local livelihoods and international environmental goals, including coastal protection, biodiversity conservation and the sequestration of carbon (C). While voluntary C market projects seeking to preserve and enhance forest C stocks offer a potential means of generating finance for mangrove conservation, their implementation faces barri...
