Crop and irrigation management strategies for saline-sodic soils and waters aimed at environmentally sustainable agriculture por Qadir, Manzoor, Oster, J.D.

“…relies on growing appropriate plant species that can tolerate ambient soil salinity and sodicity levels during reclamation of salt-affected soils.A variety of plant species of agricultural significance have been found to be effective in sustainable reclamation of calcareous and moderately sodic and saline-sodic soils.The second strategy fosters dedicating soils to crop production systems where saline andyor sodic waters predominate and their disposal options are limited.Pr oduction systems based on salttolerant plant species using drainage waters may be sustainable with the potential of transforming such waters from an environmental burden into an economic asset.Such a strategy would encourage the disposal of drainage waters within the irrigated regions where they are generated rather than exporting these waters to other regions via discharge into main irrigation canals, local streams, or rivers.Being economically and environmentally sustainable, these strategies could be the key to future agricultural and economic growth and social wealth in regions where saltaffected soils exist andyor where saline-sodic drainage waters are generated.…”

Kvalitetssäkring av hushållsnära avloppsfraktioner por Giers, Helena

“…Due to insufficient function, these contribute significantly to the total discharge of phosphorus to rivers and lakes, causing eutrophication. In order to reduce eutrophication and to fulfil one of the environmental quality objectives, the decision was taken by the Swedish Government in 2005 that 60 % of phosphorous in sewage sludge is to be recycled to arable land before 2015. …”
