The impact of road and railway embankments on runoff and soil erosion in eastern Spain
Abstract. Road and railway infrastructure increased in the Mediterranean region during the last three decades. This included the building of embankments, which are assumed to be a~large source of sediments and runoff. However, little is known about soil erosion rates, the factors that control them, and the processes that contribute to detachment, transport and deposition of sediments from road and railway embankments. The objective of this study was therefore to assess the impacts of road and railway embankments as a source of sediment and water, and compare them to other land use types (citrus plantations and shrublands) representative of the Cànyoles watershed to evaluate the importance o…
Rhizosphere soil indicators for carbon sequestration in a reclaimed coal mine spoil
Abstract Re-vegetation of mine spoil enhances carbon storage in both above-ground plant biomass and mine soil. The current study was conducted at the coalmine overburden dumps of Jharia Coalfield (India), with the aim to evaluate the effect of different tree species on the rhizosphere soil properties and to identify key rhizosphere soil indicators that influence tree biomass and carbon density. Rhizosphere soil samples were collected from five tree species ( Acacia auriculiformis , Albizia lebbeck , Cassia siamea , Delonix regia , and Dalbergia sissoo ) of the same age. An area without ground vegetation was selected as a non-rhizosphere soil. The carbon density was higher for D. sissoo and …
