1. 16. The potential nitrous oxide emissions in a permanent grassland chronosequence

   University essay from SLU/Dept. of Forest Mycology and Plant Pathology

   Author : Sandra Lillsjö Kronblad; [2023]
   Keywords : nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

   Abstract : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.

4. 18. Companion crops in winter oilseed rape : effects on nitrogen concentration, biomass, and prevalence of weeds at the end of autumn growth

   University essay from SLU/Dept. of Crop Production Ecology

   Author : Stina Johansson; [2023]
   Keywords : biomass; companion crops; intercropping; legumes; nitrogen concentration; organic cultivation; weeds; winter oilseed rape;

   Abstract : Intercropping can be used as a management system to promote higher yield as well as less weeds,diseases, and insect damage. Legumes are a commonly used companion crop (CC) in intercropping due to the benefit of nitrogen (N) fixation. READ MORE

5. 19. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Anne Rebotzke; [2023]
   Keywords : mercury; lake sediment; primary productivity; algal scavenging; biogenic silica; diatom proxy; chlorophyll-a; organic matter;

   Abstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE

6. 20. Towards a Fourth Food Regime? A sustainability analysis on modern agriculture in Schwäbisch Hall, Germany

   University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

   Author : Lea Noemi Feinauer; [2023]
   Keywords : Food Regimes; Actor-Network-Theory; Sustainable Agriculture; Common Agricultural Policy; Climate Change; Sustainable Consumption; Food Security;

   Abstract : At my thesis’s core is the transformation of the agricultural industry based on the framework of food regimes established by Philip McMichael and Harriet Friedmann. The framework of food regimes will guide the analysis of recent agricultural developments towards sustainability. READ MORE
