  1. 1. Quantifying changes in soil bioporosity in subarctic soils after earthworm invasions

    University essay from

    Author : Joel Fransson Forsberg; [2021]
    Keywords : Biopores; macropores; geoengineering earthworms; X-ray tomography;

    Abstract : Pores provide important hotspots for chemical and biological processes in soils. Earthworm burrows affect the macropore structure and their actions may create new preferential pathways for water and gas flow within soils. This, in turn, indirectly affect plants, nutrient cycling, hydraulic conductivity, gas exchange, and soil organisms. READ MORE

  3. 2. Influence of cropping and fertilization on soil pore characteristics in a long-term field study

    University essay from SLU/Dept. of Soil and Environment

    Author : David Nimblad Svensson; [2020]
    Keywords : X-ray CT; soil structure; biopores; connectivity;

    Abstract : Soil porosity, pore size distribution and pore characteristics such as connectivity are important for a range of soil processes including ease of root growth and air and water transport. The pore structure is therefore an important part of soil fertility. READ MORE

  4. 3. Imaging the 3D distribution of cation adsorption sites in undisturbed soil

    University essay from SLU/Dept. of Soil and Environment

    Author : Hannes Keck; [2016]
    Keywords : cation exchange capacity; X-ray scanning; soil structure; contrast agent; heterogeneity;

    Abstract : Most soil system models assume that the cation adsorption sites in soils are accessible and homogeneously distributed in space. This assumption is likely to be invalid, which may have significant consequences on the performance of these models. READ MORE

  5. 4. Biologisk nedbrytning av plogsulan : växtföljder, klimat och användningsområden

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Björn Larsson; [2015]
    Keywords : bioporer; pålrot; reducerad bearbetning; direktsådd; plogsula; daggmask; miljö; växtnäring; biodiversitet;

    Abstract : Strukturrationaliseringen i jordbruket påverkar i stor utsträckning lantbruksmaskinernas storlek vilket gör att vi går mot allt större och tyngre maskiner. Detta påverkar i stor utsträckning markpackningen. Ett sätt att komma förbi detta är att använda sig av fasta körspår (CTF ). READ MORE
