  1. 1. Soil salinity as a driver of microbial community structure and functioning

    Author : Kristin Rath; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Soil salinization; Soil Microbiology; soil microbial community; Bacteria; Aerobic; Fungi; Drying-rewetting; Microbial growth; Microbial biomass; Soil respiration; salinity tolerance; Saline soils; Salinity gradient;

    Abstract : Soil salinization is a pressing agricultural problem in many areas of the world, particularly in areas heavily reliant on irrigation agriculture. While the negative effects of salinity on crop plants have been widely studied, its effects on soil microorganisms have received less attention, and the impact of soil salinity on both microbial community structure and functioning is not well understood.

  3. 3. Pollution-Induced Community Tolerance (PICT) of Bacteria: Evaluation in Phenol- and Antibiotic Polluted Soil

    Author : Louise Aldén; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antibiotics; Bacteria; Community; Fungi; Leucine incorporation; Phenols; Soil; Pollution-Induced Community Tolerance PICT ;

    Abstract : The effects of organic pollutants on the soil microbial community were studied in this work. The main aim was to evaluate the use of pollution-induced community tolerance (PICT) in studying the effects of pollution. The leucine incorporation technique (indicating bacterial growth) was used to monitor changes in tolerance. READ MORE

  4. 4. Diversity of soil microbial communities: In the perspective of targeting functional genes

    Author : Lokeshwaran Manoharan; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Soil; metagenomics; sequence capture; microbial communities; functional diversity; taxonomic diversity;

    Abstract : Abstract Intensive land use in agriculture can lead to higher loss of biodiversity in soils and subsequently carbon due to tillage and application of pesticides and fertilizers. The microbial communities are pivotal to ecosystem processes in soil such as nutrient cycling, soil formation and plant productivity and thus are affected by land use. READ MORE

  5. 5. Tillage practices and their impact on soil organic carbon and the microbial community

    Author : Sofia Hydbom; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tillage; Agriculture; Long-term field experiment; Microorganism; Clayey soil; Soil organic carbon; Farmer; Sweden;

    Abstract : Soil microorganisms are important for climate regulation as well as for plant nutrition. In agricultural soils the microorganisms are affected by management choices, like which type of tillage that is used. READ MORE
