  • Aspects of manganese nutrition in filbert trees

    Creator:
    Silberman, Ricardo S.
    Abstract:
    Lime was applied at different rates to filbert trees grown in containers in an acid soil. As lime application rate increased, the leaf Mn and extractable soil Mn were significantly reduced. In control trees leaf Mn was over 1300 ppm, but no growth reduction or Mn toxicity symptoms were found....

  • Assessing the role of reactive metal species in soil organic matter cycling using chemical imaging

    Creator:
    Keiluweit, Marco
    Abstract:
    Intimate associations with reactive metal species permanently protect soil organic matter (SOM) from microbial access and oxidation, contributing to the build-up of organic carbon (C) stocks in soils. It is increasingly recognized, however, that such associations can be reversible and that reactive metal species might even facilitate the oxidation of...
