K  aPhosphorus in actionbbiological processes in soil phosphorus cycling.  aHeidelberg: Springerc2011  a483 p.  a(Soil biology, v. 26).  aPhosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the existing, up-to-date information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques, characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions, while aspects of P management with respect to animal production and cropping are also presented. The final chapter examines the interactions between global change and P cycling.  amycorrhizae  aPhosphorus  arhizosphere  asoil biology  asymbiosis  aBiologia do Solo  aMicorriza  aRizosfera  aSimbiose  aCiclo de nutrientes  aNutrient cycles1 aOBERSON, A.1 aFROSSARD, E.
