  5. 3. Subsoil improvement for sustainable intensification : impact of loosening with straw incorporation or liming on subsoil properties, crop performance and water quality

    Author : Gizachew Tarekegn Getahun; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Subsoil has a high capacity for nutrient and water retention, but arable subsoil is often nutrient poor, carbon-deficient and compacted, affecting both root growth and yield. In field and lysimeter experiments, this thesis investigated the effects of subsoil loosening and loosening with cereal straw incorporation (24-60 Mg ha-1) (loosening + straw) on crop yield, soil properties (bulk density, penetration resistance, moisture characteristics) and leaching.

  6. 4. Characterisation of residues : Release of contaminants from slags and ashes

    Author : Ann-Marie Fällman; Rob N.J. Comans; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Residues from industrial processes as well as from energy production utilities have in many cases properties similar to geological materials. They can be used as filling and construction materials if the net environmental impact and the technical properties are acceptable. READ MORE

  7. 5. Road runoff quality in cold climates

    Author : Camilla Westerlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : The main objective of the doctoral thesis was to investigate the complex processes and influencing factors affecting snowmelt-induced runoff and snowmelt quality in a cold climate under wintry conditions compared to non- winter conditions in areas with a warmer climate. In order to improve the understanding and knowledge of road-runoff quantity, quality and pollutant transport, snowmelt and rainfall runoff were studied and characterized in the laboratory and in the field, respectively.
