  1. 1. Nutrient concentrations before and after the Focus on Phosphorus project in E23 catchment

    University essay from SLU/Dept. of Soil and Environment

    Author : Åsa Larsson; [2018]
    Keywords : phosphorus; Greppa fosforn; two-stage ditch; structure liming; sedimentation pond;

    Abstract : Between 2007-2014, as part of the Greppa Näringen, there was a subproject on phosphorus losses called Focus on Phosphorus (FoP; Greppa Fosforn). Previous measures on eutrophication mainly focused on nitrogen leakage, whilst the purpose of FoP was to test already known mitigation methods against phosphorus losses in the field. READ MORE

    Author : Johan Knutsson; [2018]
    Keywords : strukturkalk; kalkförsök; markstruktur; fosforläckage; näringsläckage;

    Abstract : Structural liming is something that will positively affect the hard clay soil in theory. This work should demonstrate that it is also so in practice. The purpose of this work was to study the effect on soil struc-ture after spreading structure lime at different time, different incorporation depths and different rates. READ MORE

    Author : Henrik Roth; [2018]
    Keywords : strukturkalkning; eutrofiering; fosfor;

    Abstract : In this review article, the effect of structural liming on clay soils, which have a high leakage potential for phosphorus (P), was analyzed. The purpose was to investigate structural liming as a method to reduce the impact of agriculture on eutrophication of water sources. READ MORE

  5. 5. Kalkningens påverkan på växthusgasemissioner från odlad torvjord
