  1. 11. Relating the impacts of regenerative farming practices to soil health and carbon sequestration on Gotland, Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Laerke Daverkosen; Alena Holzknecht; [2021]
    Keywords : regenerative agriculture; soil health; carbon sequestration; Gotland Sweden ;

    Abstract : Land degradation, greenhouse gas emissions and biodiversity loss through agriculture are some of the greatest challenges we are facing today. Fertile and productive soils are the basis of life on this planet and need to be protected and restored to support a growing population and lower negative impacts of climate change. READ MORE

  3. 12. Effects of wild boar (Sus scrofa) on soil processes and tree growth

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Andreas Lundgren; [2021]
    Keywords : Wild boars; soil processes; tree growth; Vildsvin; markprocesser; trädtillväxt;

    Abstract : Wild boars (Sus scrofa) have increased rapidly in population size and home range since their reintroduction to the Swedish fauna. Through their rooting behaviour, the boars can cause great disturbance to the ecosystem. READ MORE

  4. 13. Effects of organic matter depletion on fungal communities in a reconstructed boreal forest podzol system

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

    Author : Katharine Alice King; [2020]
    Keywords : ectomycorrhizal fungi; fungal community structure; fungal diversity; high throughput sequencing; podzol; soil horizons;

    Abstract : The boreal forest biome serves as a valuable resource, both as a source of wood, pulp and biofuel, and as a sink of atmospheric carbon (C). A large proportion of C is sequestered to the soil of the boreal biome, however belowground processes are still poorly understood. READ MORE

  5. 14. Reimagining agriculture with perennial crops : a study on the diffusion of innovation and soil ecosystem services in the new perennial grain Kernza

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Robin Meijer; [2020]
    Keywords : Intermediate Wheatgrass; Kernza; Thinopyrum Intermedium; perennial grain; polyculture; wheat; annual; microbial biomass; soil microbial community structure; PLFA; NLFA; sustainability; agroecology; ecological intensification; innovation;

    Abstract : Perennial crops have been identified as a pathway to implement ecological intensification, which in extent could make agriculture more socio-economically and ecologically sustainable. This is a master thesis in Agroecology – a growing scientific discipline that aims to investigate problems in the food system using a holistic and transdisciplinary approach, incorporating and integrating both natural and social sciences to transform the food system.

  6. 15. Effects of nitrogen quality and quantity on weed-crop competition : a greenhouse experiment with Avena sativa and Avena fatua

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Lukas Hallberg; [2019]
    Keywords : weed-crop competition; resource pool diversity; soil microbes; weed community;

    Abstract : The intensification of agricultural activities has provided unprecedented increases in crop production. In the light of this development concerns have been raised about its negative environmental impact. High-input farm management has further reduced the weed diversity and shaped weed communities to consist of a few highly competitive weed species. READ MORE
