  1. 1. En hållbart intensifierad slåttervall med vitklöver : en litteratursammanställning

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Johanna Forss; [2023]
    Keywords : etablering; kväve; skördesystem; Trifolium repens; vall; vitklöver;

    Abstract : Fördelarna med att inkludera vall i växtföljden är många, till exempel kolinlagring, markförbättrande egenskaper och ogräsbekämpning. Intresset för odling av vall ökar när det finns fler avsättningsmöjligheter och ses som ett medel för att uppnå en hållbar intensifiering av odlingssystemet. READ MORE

  3. 2. System ecology of legumes mixes in ley production : impact on pollinating insects and further implications for production in northern Sweden

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

    Author : Philippe Simon; [2023]
    Keywords : Ley production; Nitrogen fixation; Pollination ecology;

    Abstract : The population and diversity of pollinating insects in Europe are declining, partly due to lossof habitat. In agricultural landscapes, farming practices with more intensified land use haveincreased. In Swedish agricultural habitats, most ley production is dominated by grass and red clover (Trifolium pratense). READ MORE

  4. 3. Does irrigation data matter in life cycle assessments?

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Olof Andersson; [2023]
    Keywords : Agent-Based Life cycle assessment; Arable grass rotation; Biofuel; Irrigation; Sensitivity analysis; Water footprint; Earth and Environmental Sciences;

    Abstract : Biofuels are seen as a key substitute for fossil fuels and an essential tool for mitigating climate change. A sensitivity analysis was conducted on the AB-LCA (agent-based life cycle assessment) made by Raül López i Losada and his research team. READ MORE

  5. 4. Protein digestibility of biorefined juice from fresh and ensiled ley crops in growing pigs

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

    Author : Jhon William Perez Davila; [2023]
    Keywords : protein digestibility; amino acids; ley crops; silage; biorefinery; press juice; growing pigs;

    Abstract : The study aimed to evaluate the protein and amino acid digestibility of press juice from biorefined ley crops in the form of fresh (FPJ) and silage (SPJ) when included as an ingredient in liquid diets for pigs. The juice was extruded from ley crops mixture (grass-clover). READ MORE

  6. 5. Combining GHG Emissions and Soil Carbon Changes as a Single Metric to Evaluate Agricultural Policy Promoting Biomass for Biofuels

    University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Malin Lane; [2022]
    Keywords : Gräsvallar; klimatpåverkan; kolinlagring; jordbruk; biomassa; biobränslen.; Earth and Environmental Sciences;

    Abstract : Incorporating a multi-year grass ley into an arable crop rotation can increase soil organic carbon stocks, reduce carbon emissions and provide feedstock for biogas. This thesis set out to study how a policy promoting agricultural biomass for biogas impacts GHG emissions and carbon sequestration on a regional level over a temporal scale of 20 years. READ MORE
