Soil cation exchange capacity (CEC) depends on the extent and negative charge density of surfaces of soil mineral and organic components. Soil water sorption also depends on the extent of such surfaces, giving thus way to significant relationships between CEC and hygroscopic moisture (HM) in many soils. In this work, we explored whether CEC could be accurately predicted from HM in agricultural ...

Moses Rock dike is a Tertiary diatreme containing serpentinized ultramafic microbreccia (SUM) located on the Colorado Plateau in Utah. Field evidence indicates that SUM was emplaced first followed by breccias derived from the Permian strata exposed in the walls of the diatreme and finally by complex breccias containing basement and mantle-derived rocks. SUM is primarily found dispersed througho...

Abstract This work aimed at evaluating the impact of human activity and geology on surface water quality Ouled Mellouk dam (northwestern Algeria). Specifically, methodology aims to assess seasonal variations several parameters (EC, TDS, pH, SO42−, Cl−, Ca2+, Na+, HCO3−, NO3−, PO43− Mg2+, organic matter, suspended solids, BOD5, COD) from 2007 2013 define processes controlling mineralization poll...

Rainfall and biocrusts are important sources of temporal spatial environmental heterogeneity niche differentiation for annual plants, a major component diversity in drylands. Therefore, global change processes comprising shifts rainfall timing drought exacerbation, together with biocrust disturbance may affect species coexistence result disrupted patterns. In this study, we experimentally evalu...
