1. 16. Integrating horticultural and arable crops : a sustainable way to increase vegetable production in Scania?

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

   Author : Stina Helena Mortensen; [2022]
   Keywords : Horticulture; agriculture; vegetables; crop rotation; crop sequence; diversification; integration; ecosystem services; farmers’ attitudes;

   Abstract : Modern arable production is associated with a highly homogenous landscape with few cultivated species and is relying heavily on external chemical inputs. Intensive vegetable production, on the other hand, is associated with environmental costs such as increased risk of nutrient leaching and loss of soil organic matter. READ MORE

3. 17. Biokol som tillsats i vallensilage utfodrat till mjölkraskvigor : inverkan på konsumtionsförmåga, smältbarhet, träckens konsistens och färg, samt djurens renhet

   University essay from SLU/Dept. of Animal Nutrition and Management

   Author : Ida Milton; [2022]
   Keywords : Biokol; Smältbarhet; Vallensilage; Aktivt kol; Mjölkraskvigor; Konsumtionsförmåga; Träckkonsistens; Färg; Renhet;

   Abstract : Biokol är en produkt som tillverkas av organiskt material eller biomassa i en process som kallas pyrolys, då materialet upphettas i en temperatur från 350 till 1000 ̊C i en syrefri miljö. Biokol är lagringsstabil under lång tid innan den bryts ned och fungerar därför som kolsänka. READ MORE

4. 18. Impacts of peatland drainage on soil properties : a study of drainage effects on boreal peatlands in northern Sweden

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

   Author : Frederika Klaus; [2022]
   Keywords : Boreal peatlands; Bulk density; Carbon; Greenhouse gas; Isotopes; Nitrogen; Organic matter; Peatlands; Peatland drainage; Peatland restoration;

   Abstract : Peatlands cover approximately 3% of the terrestrial surface on Earth and perform several important ecosystem functions, such as carbon storage and water retention. During the late 19th and early 20th centuries, approximately 2 million hectares of peatlands in Sweden were drained to manage the land for forestry and agriculture. READ MORE

6. 20. Drivers of decomposition across Sphagnum bog margins

   University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

   Author : Emil Nordström; [2022]
   Keywords : Peatlands; tea bag index; edge effects; carbon storage; carbon sequestration; waterlogging; Torvmark; kanteffekter; kollagring; koldioxidbindning;

   Abstract : Peatlands provide multiple ecosystem services, including extensive carbon sequestration and storage, yet many peatlands have been degraded or destroyed. Peatlands carbon storage capacity is connected to inherently low decomposition rates, causing the build-up of organic matter.
