  2. 6. Influence of soil amendments and soil properties on macro– and micronutrient availability to microorganisms and plants

    Author : Atefeh Ramezanian Bajgiran; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Utilising by-products from industrial and domestic activities and from bioenergy production is one of the new ways of recovering and re-using nutrient resources in agriculture. However, these by-products can potentially add toxic elements or alter soil properties in ways that harm the soil and related environments. READ MORE

  4. 7. Novel advances using sewage sludge in engineered dry covers for sulphide mine tailings remediation

    Author : Peter Nason; Charles Cravotta; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : Effective remediation of sulphide-bearing mine tailings is a fundamental aspect in mine plan development. Novel solutions to replace virgin materials in engineered dry cover amendments using sewage sludge biosolids (SS) were evaluated in laboratory-, pilot-, and field-scale experiments. READ MORE

  5. 8. Soil Remediation and Sustainable Development : Creating Appropriate Solutions for Marginalized Regions

    Author : Henrik Haller; Anders Jonsson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The scope of this doctoral thesis is appropriate soil remediation methods for marginalized regions that go beyond pollution reduction targets and include strategies to support sustainable development. Contaminated soil from industrial or agricultural activities poses potential health threats to animals and humans and also threatens economic systems by making land unsuitable for agriculture and other economic purposes.

  6. 9. Biological Treatment of Oily Sludge and Sediments

    Author : Mait Kriipsalu; Chalmers tekniska högskola; []
    Keywords : bioremediation; refinery; aerobic biotreatment; flocculation-flotation unit FFU ; petroleum hydrocarbons; oily sludge; static biopile; PAHs; sediments;

    Abstract : AbstractOily sludge, generated in refineries or in other industrial sectors, and oil-containing sediments, removed from water bodies during remediation works, pose an environmental problem. A common feature between both is their high water content, and variable content of organic and inorganic contaminants, which complicates their treatment. READ MORE

  7. 10. The hidden half of the meadow : Interactions between drought, soil carbon, roots and soil microbial communities

    Author : Daniela Guasconi; Gustaf Hugelius; Sara Cousins; Stefano Manzoni; Petra Fransson; David Johnson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; soil; soil carbon; soil ecology; roots; root traits; microbial communities; grasslands; climate change; drought; land management; compost; naturgeografi; Physical Geography;

    Abstract : Soil is a hidden ecosystem which harbours plant roots and countless microorganisms, vital for sustaining life aboveground. These belowground communities provide essential ecosystem services like soil stabilisation and organic matter decomposition. READ MORE
