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

    Författare :Daniela Guasconi; Gustaf Hugelius; Sara Cousins; Stefano Manzoni; Petra Fransson; David Johnson; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Linking root traits and plant-soil feedbacks to environmental change in the sub-arctic tundra

    Författare :Clydecia Spitzer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Plant community assembly processes shape the composition and abundances of species, and encompass functional traits and resource acquisition strategy of species, biotic interactions and abiotic filtering. Hence, an understanding of these complex processes requires disentangling the effects of multiple factors influencing plant community assembly. LÄS MER

  4. 3. Associations among early-season root and shoot traits, nutrient use efficiency and grain yield of spring wheat

    Författare :Hui Liu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Nutrient-efficient and high-yielding spring wheat is needed in high-latitude regions. The aims of this thesis were: (1) to evaluate the effects of soil compaction and differential weather conditions on plant growth and grain yield, (2) to identify critical nutrient elements limiting plant growth and grain yield, and (3) to identify root and shoot traits at an early growth stage (early vigor) influencing nutrient use efficiency and grain yield of spring wheat.

  5. 4. Priming of carbon and nitrogen mineralization in forest soils

    Författare :Saeed Alaei; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Soil organic matter; C:N imbalance; root exudates; priming; Extracellular enzymes; Soil organic matter; C:N imbalance; root exudates; priming; Extracellular enzymes;

    Sammanfattning : Decomposition of soil organic matter (SOM) contributes significantly to the global carbon (C) cycle and climate feedbacks. SOM decomposition depends on soil microbial activities, and these activities are driven by the availability of C and other nutrients. LÄS MER
