Assessment of the main factors affecting the dynamics of nutrients in two rainfed cereal watersheds
Nutrient dynamics and factors that control nutrient exports were observed in two watersheds, namely Latxaga and La Tejería, with similar climatic and management characteristics throughout 10 years (2007–2016). Similar ... -
Dissolved solids and suspended sediment dynamics from five small agricultural watersheds in Navarre, Spain: a 10-year study
Dissolved solids (DS) and suspended sediment (SS) loads are considered relevant environmental problems. They are related to a wide range of on-site and off-site impacts, such as soil erosion or salinization of water bodies. ... -
Evolution and assessment of a nitrate vulnerable zone over 20 years: Gallocanta groundwater body (Spain)
Nitrate pollution from agricultural sources is one of the biggest issues facing groundwater management in the European Union (EU). During the last three decades, tens of nitrate vulnerable zones (NVZ) have been designated ... -
Feasibility of using rural waste products to increase the denitrification efficiency in a surface flow constructed wetland
A surface flow constructed wetland (CW) was set in the Lerma gully to decrease nitrate (NO3-) pollution from agricultural runoff water. The water flow rate and NO3 - concentration were monitored at the inlet and the outlet, ... -
Grey water footprint as an indicator for diffuse nitrogen pollution: the case of Navarra, Spain
Nitrogen is an essential element for plant growth, while its application and associated pollution is a worldwide concern. Generally, diffuse source pollution and its impacts on ecosystem health are difficult to monitor and ... -
Irrigation implementation promotes increases in salinity and nitrate concentration in the lower reaches of the Cidacos River (Navarre, Spain)
The shift from rainfed to irrigated agriculture is associated with a change in the fertilization rates due to increases in expected production and the fact of growing more N demanding crops. In addition, the circulation ... -
Runoff, nutrients, sediment and salt yields in an irrigated watershed in southern Navarre (Spain)
The environmental impact of irrigated agriculture on water quality was assessed in Landazuria watershed (Navarre, northeast Spain), a 479.5 ha watershed with 53% of irrigated agricultural land. In the framework of a long-term ... -
Shifts in crane migration phenology associated with climate change in Southwestern Europe
Gallocanta lagoon, NE Spain, is one of the main stopover and wintering areas of Common Cranes (Grus grus) migrating through Western Europe. We investigated how the water level of the lagoon where cranes roost, precipitation, ...
