  1. 1. Högfrekventa mätningar med sensorer för transportberäkning av totalfosfor i vattendrag

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

    Author : Nora Ottander; [2020]
    Keywords : turbiditet; fosfor; sensor; transportberäkning; övergödning;

    Abstract : Large areas in the Baltic Sea suffer from eutrophication, due to excessive input of nutrients, mostly nitrogen and phosphorus, from surrounding coasts. The transfer of phosphorus is mostly riverine. READ MORE

  2. 2. Multifunktionella skyddszoner : minskade fosforförluster, ökad pollinering och andra ekosystemtjänster

    University essay from SLU/Dept. of Soil and Environment

    Author : Kajsa Hillberg; [2020]
    Keywords : kantzoner; fosfor; avrinning; pollinerare;

    Abstract : Användningen av skyddszoner är en gammal metod för att förhindra att föroreningar och näringsämnen når vattendrag, sjöar och hav från jordbruksmark. Men dagens effektiviserade jordbruk innebär fler påfrestningar på miljö och klimat. Markanvändningen ska räcka till att både producera mat och uppnå flera ekosystemtjänster. READ MORE

  3. 3. Re-sourcing soil fertility : assessing the soil amendment potential of farm household resources and wastes in Bolo Silasie, Ethiopia

    University essay from SLU/Dept. of Soil and Environment

    Author : Jorunn Hellman; [2020]
    Keywords : nutrient recovery; manure management; ecological sanitation; material flow analysis; East African agriculture;

    Abstract : The global agriculture of today is to a high degree dependent on mineral fertilisers that through a constant accumulation of nitrogen (N) and phosphorus (P) in the biosphere contribute to greenhouse gas emissions and eutrophication of water bodies. At the same time, agricultural productivity around the world is largely constrained by low inputs of plant nutrients. READ MORE
