  4. 2. Mechanical properties of excavated sulfur rich soil stabilized with cement - A laboratory and field experiment

    Author : Alaleh Ziagharib; Christian Maurice; Josef Macsik; Qi Jia; Jan Laue; Bo Vesterberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sulfur-rich soil; Mixing; Sampling; Unconfined compressive strength; stabilization; Porosity; Water content; Consistency limits; Geoteknik; Soil Mechanics;

    Abstract : Sulfide soils are silty soils, often found in saturated conditions, under the groundwater level. Characteristics of these soils, including particle size distribution and consistency limits along with chemical composition and environmental properties, cause excavation to be necessary for construction purposes.

    Abstract : The objective of this thesis was to quantify differences between adjacent patches with and without ground flora of Deschampsia flexuosa L. Trin or Anemone nemorosa L. in two acid European beech (Fagus sylvatica L.) forest floors in south-west of Sweden. READ MORE

  6. 4. Potential of Acacia angustissima, Leucaena pallida and Mimosa scabrella in agroforestry systems on a Rwandan Ferralsol

    Author : Marguerite Mukangango; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Agroforestry using coppicing legume trees and shrubs is a way to improve livestock fodder quality and soil fertility in the tropics. However, tree establishment and appropriate management are challenging, hampering their integration into agriculture and livestock systems. READ MORE

  7. 5. Forestry impact on water quality: a landscape perspective on dissolved organic carbon

    Author : Jakob Schelker; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Dissolved organic carbon (DOC) is a fundamental variable defining boreal stream ecosystems. In this thesis the impact of forestry practices that are commonly performed in the boreal regions of Scandinavia for stream water quality were evaluated. READ MORE
