V.  aSimulation of phosphorus cycling in semi-arid grasslands.h[electronic resource]  c1977  aThe objective of this study was to construct a simulation model which organizes the processes to simulate actual flows of P in a grassland as closely as possible, indicating the constrainsts and variables whichcontrol these processes. Since certain processes can be more clearly defined in terms of quantitative rate constiats than others. We had to make assumptions where adequate information was not available. These assumptions were chosen to produce internally consistent flows throughout the system.  aGrasslands  aInorganic phosphorus  aSimulation models  aFósforo  aPastagem  aDecomposition  aOrganic phosphorus  aPhosphorus cycle  aSemi-arido  aSimualcao1 aINNIS, G.
