    Abstract : As agrarian society developed, the most fertile soils able to sustain the nutritional requirements needed for high crop yield were assigned to farming, while the more penurious soils were left to uphold the forest ecosystems. Some temperate forests are developed on acidic soils considered to be nutrient poor, as much of the inorganic nutrients are entrapped in poorly weatherable soil minerals and not easily accessed by plant roots.

  4. 4. Hydroxamate Siderophores and Low Molecular Mass Organic Acids in Terrestrial and Aquatic Environments Determined by Liquid Chromatography Mass Spectrometry

    Author : Sofia Essén; Ulla Lundström; Dan Bylund; Mittuniversitetet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi;

    Abstract : Siderophores are low molecular mass organic compounds with high iron(III) stability constants. They are produced by many microorganisms, often in combination with low molecular mass organic acids (LMMOAs). Both siderophores and LMMOAs accelerate mineral weathering, thereby enhancing mineral nutrient availability. READ MORE

  5. 5. Microbe-mineral interactions in soil : Investigation of biogenic chelators, microenvironments and weathering processes

    Author : Engy Ahmed; Sara Holmström; Roger Finlay; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Podzol; Biotite; Apatite; Oligoclase; Microbial attachment; Siderophores; Soil microorganisms; geokemi; Geochemistry;

    Abstract : The interplay between geology and biology has shaped the Earth during billions of years. Microbe-mineral interactions are prime examples of this interplay and underscore the importance of microorganisms in making Earth a suitable environment for all forms of life. READ MORE
