16. Biochar from separated digestate and pig manure as soil amendment
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and EnvironmentSammanfattning : 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. LÄS MER

19. Utfodring med ensilage till slaktgris : effekter på köttkvalitet och fettsyrasammansättning
Kandidat-uppsats, SLU/Dept. of Animal Nutrition and ManagementSammanfattning : Ensilage är en potentiell proteinkälla till gris då vallens aminosyraprofil passar grisens behov bra. I Sverige är förutsättningarna för vallodling goda och vallen har positiv inverkan på odlingsmarken. Vallen kan även skapa ett mervärde då den har positiva effekter på grisens välfärd samt är lokalt odlad. LÄS MER
20. Impacts of peatland drainage on soil properties : a study of drainage effects on boreal peatlands in northern Sweden
Master-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : 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. LÄS MER
