The installation of desalination plants close to ecosystems of interest may have environmental impacts that make corrective measures necessary. Especially, wetlands (which are water-dependent ecosystems) are prone to degradation. This is the case for the Agua Amarga salt marsh (SE Spain), that includes an abandoned solar saltworks and surrounding, topographically higher zones, in which the groundwater...
Many laboratory and field studies have assessed the use of geotextiles for soil conservation, identifying the salient properties of geotextiles for an adequate slope protection. However, the influence of geotextiles on vegetation development has received less attention. In the present study, the influence of several geotextiles (a jute net, a coir blanket and a 3D polyester geogrid placed in two positions)...
This study reports the soil–plant relationships within a protected landscape in semiarid SE Spain that includes salt marshes and temporary streams and that is affected by agricultural water leaching. The main objective was to establish a conceptual model in order to use vegetation as bioindicator of soil conditions. With this model, environmental changes – based on the observation of vegetation –...
Grape production is an ancient and important activity, particularly in Spain. Within this country, Navarre is one of the best vine-producing regions. Despite the importance of the vine crop, any quantification of soil erosion rates on a pluri-decennial scale under this world-wide land use is scant. Considering that in Navarre grafting in vines was made until the 1990s directly in the field, and almost...
Twenty-one soil profiles were described, analysed and classified in a salt marsh dune system in SE Spain. Sites for sampling were selected according to micro-topographical positions and vegetation types. The pedons showed an A–C type profile. Most of the profiles at summit positions had a microbiotical crust in the upper centimetres, formed by fungal mycelia that contribute to agglutination of sand...
To properly assess soil erosion in agricultural areas, it is necessary to determine precisely the volume of ephemeral gullies and rills in the field by using direct measurement procedures. However, little information is available on the accuracy of the different methods used. The main purpose of this paper is to provide information for a suitable assessment of rill and ephemeral gully erosion with...
