Abstract:
... Mercapto-palygorskite (MP) is a novel immobilization material for cadmium (Cd) pollution, but the immobilization mechanism on alkaline Cd contaminated soil is not completely clear. In this paper, field experiment was carried out to study the effect of MP on the transfer of Cd in aggregates at different depth, the contribution of soil aggregates to the reduction of Cd in bulk soil and the immobiliz ...

Abstract:
... AIMS: The mechanism by which species diversity drives productivity in different ecosystems is controversial, possibly due to the confounding effects of key environmental variables. Karst ecosystems are fragile and are at great risk of species loss. In these ecosystems, soil depth is a key driver of community diversity and productivity. However, the influence of soil depth on the relationship betwe ...

Abstract:
... Karst water is an extremely important resource and can respond to precipitation events quickly due to the high rock exposure rate, shallow and uneven soil layers, and various crack sizes. The impacts of this special rock–soil structure type on hydrological processes are difficult to quantify,mainlybecause the karst subsurface structure is very complex. In this study, lysimeters representing four r ...

Abstract:
... The genus Calonectria includes species that are pathogens of many plants. Calonectria leaf blight is a serious threat to Eucalyptus plantations in China and elsewhere in the world. Some Calonectria recovered from the surface layer (<20 cm) of soils can cause typical leaf blight symptoms on Eucalyptus trees. However, pathogenicity tests of Calonectria species from deeper soil layers have not been c ...

Abstract:
... Soil water is the dominant factor controlling evapotranspiration (ET) in arid and semi-arid regions. However, the widely used ET simulation models, such as the Shuttleworth-Wallace model (S–W model), are insufficient in simulating the direct influence of soil moisture (SM), especially in the root zone. Based on SM and ET field data, we found that the influence of SM on ET increased with soil depth ...
