  • Bussell, Jennifer Sian; Gwynn-Jones, Dylan; Griffith, Gareth W.; Scullion, John (2012-08)
    UV-B radiation and elevated CO2 may impact rhizosphere processes through altered below-ground plant resource allocation and root exudation, changes that may have implications for nutrient acquisition. As nutrients limit ...
  • Gee, John Henry Robert; Barber, Iain; Scullion, John (Cyngor Cefn Gwlad Cymru, 2008-06-01)

  • Scullion, John; Neale, S.; Philipps, L. (2002-09)
    Earthworms influence a wide range of soil properties. They are affected by practices that perturb the soil or change organic inputs. This study compared populations in UK organic and conventional rotations differing in ...

  • Jones, Alan G.; Scullion, John; Ostle, Nick; Levy, Peter E.; Gwynn-Jones, Dylan (2014-12)
    We appraise the present geographical extent and inherent knowledge limits, following two decades of research on elevated CO2 responses in plant communities, and ask whether such research has answered the key question in ...
  • Scullion, John; Smith, Andrew; Jones, Dylan; Jones, David L.; Godbold, Douglas L. (2014-08)
    tElevated atmospheric CO2induced reductions in litter quality can adversely affect earthworms. However,this understanding is based on laboratory rather than field research and relates to single earthworm andtree species. ...
  • Scullion, John; Neal, S.; Philips, L. (2007-11)
    Earthworm populations and their casting/burrowing activities were recorded in rotations on paired organic and conventional farms. Earthworm abundance was often higher in organic systems, the proportion of ley being a key ...

  • Marashi, Abdul Redha Abdulla; Scullion, John (2003-05-01)
    Topsoils affected by surface mining suffer severe physical degradation and lose most of their earthworm populations. After mining, replaced soils are planted to grassland and managed to improve soil structure. Earthworm ...

  • Tuffen, F.; Eason, William R.; Scullion, John (2002-07)
    To measure P transfers, two small pots, placed 1 cm apart and each containing one leek (Allium porrum L.) plant, were embedded within a larger sand volume. Mesh windows on the facing pot sides allowed the penetration of ...

  • Crotty, Felicity Victoria; Fychan, Aled Rhun; Scullion, John; Sanderson, Ruth; Marley, Christina Louise (2014-09-01)
    Soil biology is key to maintaining soil health, and soil health is fundamental to the sustainability of agricultural systems. Alternative forages have higher concentrations of essential nutrients, and different rooting ...
  • Fychan, Rhun; Crotty, Felicity; Scullion, John; Sanderson, Ruth; Marley, Christina (2015)
    Using shallow tillage (e.g. direct drilling) is one approach farmers could use to reduce establishment costs within dairy systems but soils are often compacted by machinery during field operations. Research has shown that ...
  • Khan, M.; Scullion, John (2002-05)
    Sewage-sludge may improve soil fertility but there is concern about effects of sludge metals on soil micro-organisms and microbial processes. In a series of laboratory incubations of soil–sludge mixes, effects of varying ...

    Farmland is a major land cover type in Europe and Africa and provides habitat for numerous species. The severe decline in farmland biodiversity of the last decades has been attributed to changes in farming practices, and ...
  • Worgan, Hilary; Scullion, John; Goodacre, Royston; Huang, Wei; Draper, John H.; Elliott, Geoffrey Nigel; Bailey, Mark J.; Gwynn-Jones, Dylan; Griffith, Gareth W.; Clegg, Christopher D.; Darby, Robert M. (2003)
    The complex and dynamic nature of soil makes the assessment of soil biodiversity difficult. Findings presented here form part of a wider scheme to develop ‘bio-sampling’ methods based on earthworm cast analysis. Our overall ...
