21. Modelling climate change impacts on pesticide leaching : uncertainty and scenario analysis at field and regional scales
Abstract : Climate change projections for Sweden indicate increases in both temperature and precipitation. In a warmer and wetter climate, weed and pest pressures are likely to increase, which might in turn trigger an increased use of pesticides. READ MORE

22. Compaction and thaw deformation of frozen soil : permeability and structural effects due to freezing and thawing
Abstract : This thesis is the result of the two projects:"Deformations in winter compacted soils" and "Permeability changes in a fine-grained till due to freeze/thaw". The aim of the first project was to study whether it is possible to compact frozen soils, in road embankments etc. READ MORE

23. Modelling soil temperature and carbon storage changes for Swedish boreal forests
Abstract : With the use of a process-orientated ecosystem model andmeasurements conducted at different Swedish coniferous forestsites, abiotic and biotic interactions between tree and soilwere identified and related to governing factors. Two differentmodelling approaches to describe soil temperatures at two sitesincluding hydrological transects were tested (I). READ MORE

24. Soil Modification by adding small amounts of binders : A laboratory study
Abstract : Soil stabilization through addition of a hydraulic binder is a method frequently used to modify and improve engineering properties of soft soils. Additives like cement and lime are typically used as stabilizers. More recently, industrial by-products, such as fly ashes, cement kiln dust, blast furnace slags and other slags have been used.

25. Soil microbial responses to mild winters and seasonal change
Abstract : The aim with this thesis work was to study microorganisms response to milder winters, different seasons, and altered temperature. Winter warming treatments were established in a semi-natural temperate grassland, simulating mild winters for two years. READ MORE
