1. 1. Long-term phosphorus trends in Swedish rivers and streams : widespread and persistent nutrient decline

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Sara Camiolo; [2021]
   Keywords : eutrophication; rivers; streams; phosphorus;

   Abstract : Phosphorus (P) is often considered the limiting nutrient for freshwater productivity because of its relevant role in regulating algal production and determining community composition. The concern for increasing anthropogenic P inputs registered since the last century has shaped environmental policies around the world to limit the effects of algal bloom (also known as eutrophication) in freshwater ecosystems through the establishment of maximum threshold nutrient concentrations.

3. 2. The role of agricultural drainage in controlling the effectiveness of two-stage ditches in Sweden

   University essay from SLU/Dept. of Soil and Environment

   Author : Neerajaa Nagarajan; [2021]
   Keywords : Subsurface drainage; Absorbance flourescence spectroscopy; Suspended sediments; NO3N; NH4N; PO4P; TP values; DOM indices;

   Abstract : Increased agricultural activities are causing eutrophication in downstream water bodies. To mitigate nutrient leaching from cropland, various in-field and edge-of-field practices have been implemented. READ MORE

4. 3. Aggregatstabilitet, jordbearbetning och fosforförluster i ett typområde på jordbruksmark

   University essay from SLU/Dept. of Soil Sciences

   Author : Anna Melakari; [2005]
   Keywords : aggregatstabilitet; jordbearbetning; fosforförluster; jordbruksmark;

   Abstract : Large amounts of phosphorus (P) are lost from the arable land due to water erosion. Both phosphorus attached to particles and dissolved phosphorus (mainly phosphate) are transported away with drainage-water and surface runoff. Good soil structure is important in minimizing these losses. READ MORE
