Abstract Urbanization influences soil carbon (C) stocks and flows, which, in turn, affect soil-derived ecosystem services. This paper explores C storage urban greenspaces the Dutch city of The Hague along a transect from suburban seaside towards centre, reflecting toposequence dune to peaty inland soils. mineralisation potential were evaluated relation type greenspace categories. Several soil-q...

In recent decades, many regions in the Chad Republic Central Africa have experienced a continuous decline agricultural yields. order to determine main factors leading this yields and mainly Sorghum yields, study was conducted South-Western Chad, Sudano-Sahelian environment. Three soil profiles of variable depths, namely, M1, M2, M3, were dug along toposequence, respectively, footslope, mid-slop...

Subsurface waters circulating in an unpolluted soil of a planosolic horizon (Massif Central, France) were studied in order to determine their physico-chemical characteristics. Three water sampling sites were chosen along a toposequence according to topography. For each site, two piezometers were placed above and in the gravely and concretion-rich horizon (Feand Mnoxyhydroxides). Concentrations ...
