1. 1. Platsens betydelse för växtnäringsläckage från jordbruksmark i Sverige

   University essay from SLU/Dept. of Soil and Environment

   Author : Frida Lundell; [2023]
   Keywords : kväve- och fosforutlakning; rumslig variation; långtidsövervakning;

   Abstract : Växtnäringsläckage av kväve (N) och fosfor (P) från jordbruksmark tillför näringsämnen till hav och vattendrag. Det är viktigt att minska transporten av N och P av flera anledningar, då det bland annat är en stor bidragande faktor till övergödning. READ MORE

3. 2. Sustainable use of calcium nitrate fertilizer under variable precipitation, soil properties and crop management

   University essay from SLU/Dept. of Soil and Environment

   Author : Liliana Marcela Daza Gomez; [2023]
   Keywords : nitrogen.; calcium nitrate; ammonium-based fertilizers; urea; nitrate leaching; nitrous oxide emissions; crop yield;

   Abstract : Application of nitrogen fertilizers in agriculture contributes substantially to global greenhouse gas emissions and nitrogen leaching. Accordingly, there is a need to increase knowledge about sustainable farming practices to reduce nitrogen losses to the environment without curtailing crop harvest. READ MORE

4. 3. Utforskade dataanalys av bäckarna i Undersviks Tillväxtpark före BAG-försök

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Maja Sjöström; [2023]
   Keywords : BAG; skogsgödsling; markvatten; näringsläckage; bäckar; barrskog;

   Abstract : Förorening av vatten är ett stort problem både på lokal och global nivå. Övergödning från mänsklig aktivitet såsom jordbruk och industrier utgör ett markant hot mot våra vatten (Rheinheimer 1998), å andra sidan skulle skogsbruket kunna förbättra sin produktion med större nyttjande av gödsel.

5. 4. Ammonium and nitrate sorption by biochar

   University essay from SLU/Dept. of Soil and Environment

   Author : Yasser Alrhban; [2023]
   Keywords : biochar nitrogen; retention; dialysis; absorption; adsorption; ammonium; nitrate;

   Abstract : Biochar has recently drawn attention due to its ability to increase soil fertility, sequester carbon and its expected effect on reducing the leaching of elements from the soil, especially nitrogen. The possibility of using biochar as a soil amendment to reduce the amount of nitrogen leaching, and then reducing the quantities of nitrogen fertilizers used in agriculture to avoid the bad environmental effects has become a matter of great interest.

6. 5. Biochar from separated digestate and pig manure as soil amendment

   University essay from SLU/Dept. of Soil and Environment

   Author : Lovisa Nissen; [2022]
   Keywords : separation; screw press; incubation study; CO2 emission; N mineralization;

   Abstract : The situation in and around the Baltic Sea, with large areas with hypoxia in the sea and areas in the watershed with a high concentration of animal farms, has led to a need to increase the nutrient recycling of animal manure. High levels of phosphorus (P) in the soil lead to leaching, and by reducing the P-level in organic fertilizers, this leaching can be reduced. READ MORE
