We studied the soil and vegetation fertility of two saline wetlands located in arid (Guallar) and semiarid (Gallocanta) environments, with a mean rainfall of 346 and 488 mm, respectively. Fertility data could be useful to apply agro-environmental measures in vulnerable areas under the Nitrates Directive (91/676/EEC), as is the case of saline wetlands in agricultural areas. Soil management in semiarid lands is key to preserve diversity and to reconcile agriculture with habitats conservation.

The sampling was performed in April 2013, and the sampling sites followed a gradient in soil salinity and flooding conditions. The first 25 cm of the soil (5 cm in GA19, GA20 and GA21), the surface water, and the vegetation were sampled along a soil transect extending from the crop towards the wetlands shoreline.

This study is a result of the research project AGL2012-40100 funded by the Spanish Government (MINECO). We acknowledge the data provided by the Spanish Meteorological Agency (AEMET). E. Luna was financed by a fellowship from the Government of Aragón, Spain.
