  1. 1. The role of bed sediments for fractionation of phosphorus in remediated ditches in Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Emma Ryding; [2022]
    Keywords : Phosphorus fractionation; agricultural stream; sediment; two-stage ditch; eutrophication;

    Abstract : Sweden’s environmental quality objectives “A varied agricultural landscape” and “Zero eutrophication”, aims to ensure food production while reducing negative impact from fertilizers on the environment. The input ceilings of nutrient concentrations in the Baltic Sea are still critical. READ MORE

  3. 2. Phosphorus in the sediment of L. Hällerstadsjön: spatial distribution, fractions and release to the water volume

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : NANA OSAFO; [2016]
    Keywords : Bioavailable phosphorus; Eutrophication; Phosphorus fractionation; Phosphorus flux; Sediments.;

    Abstract : : In freshwater systems phosphorus (P) is the limiting element in the cause of eutrophication. In many Swedish lakes, causes of eutrophication have been attributed to more of internal loading than external since the external loading has been fairly well managed. READ MORE

  4. 3. Desorption of Water Soluble Phosphorus from Soil : development of a Consecutive Extraction Method

    University essay from SLU/Dept. of Soil and Environment

    Author : Klaus Jarosch; [2012]
    Keywords : consecutive phosphorus extraction; potentially releasable water soluble phosphorus; phosphorus desorption; long term field experiment;

    Abstract : A consecutive extraction method was developed which allows to determine the total amount of water soluble phosphorus in soil. For that, soil was shaken with deionized water, which was removed and replaced after one hour; this procedure was repeated ten times. READ MORE

  5. 4. Phosphorus retention in a constructed wetland - the role of sediment accretion

    University essay from Institutionen för fysik, kemi och biologi

    Author : Karin Johannesson; [2008]
    Keywords : Constructed wetland; long-term retention; phosphorus removal efficiency; sediment; sequential fractionation;

    Abstract : A low-loaded constructed wetland was investigated with respect to phosphorus retention. Since the main long-term phosphorus retention mechanism is sedimentation and sediment accretion, the study focused on these processes. READ MORE
