1. Wild plants can improve their rhizosphere chemistry in acid soils
Abstract : Growth conditions on acid soils may be hampered by low nutrient availability and phytotoxic Al (aluminium) concentrations. In this thesis I present my studies on adaptation mechanisms of wild plants to acid soils in the close root environment, the rhizosphere. READ MORE

2. Phytophthora and Oak Decline - Impact on Seedlings and Mature Trees in Forest Soils
Abstract : This thesis investigated the occurrence of soilborne species of the plant pathogenic genus Phytophthora in southern Swedish oak forests and their possible involvement in southern Swedish oak decline. The emphasis was on the impact of P. quercina on Quercus robur in acid forest soils. READ MORE

3. Soluble and Plant Available Phosphorus in Acid Soils
Abstract : The P availability and solubility differ between soils and plants seem to have different ways of utilising the P present. The many P fractions present in soil interact and are closely related to another and transformations may easily occur. Due to this more P than the soluble fraction is available to plants. READ MORE

4. Structure and function of microbial communities in acid sulfate soil and the terrestrial deep biosphere
Abstract : This thesis describes the use of different DNA sequencing technologies to investigate the structure and function of microbial communities in two extreme environments, boreal acid sulfate soil and the terrestrial deep biosphere.The first of the two investigated environments was soils containing un-oxidized metal sulfides that are termed ‘potential acid sulfate soil’ (PASS) materials.
