| Abstract/Contents: | "In this investigation, the accumulation, mineralization and annual cycle of organic P has been studied in grassland ecosystems of a Z. japonica grassland and a M. sinensis grassland on Mt. Kwanak. The basic models of the accumulation and mineralization for ash components of a grass-litter have been presented as the equations (1), (2), and (3). The equations (7)-(10) for organic P are derived from these basic concepts. There was a highly significant relationship between organic matter and organic P. The estimates between organic matter and organic P correlated very high significance. The factors k or k' of mineralization or organic P for the Z. japonica and M. sinensis grasslands were k=0.412 or k'=0.292 and k=0.224 or k'=0.183, respectively. The time required for a cycle to be completed from organic P to inorganic P of 50, 95 and 99 % are 3.9, 16.7 and 27.8 years in the Z. japonica grassland and 4.1, 17.7 and 29.4 years in the M. sinensis grassland. The annual P cycle formulae for mineralization were based on the equations (5), (11) and (12). Annual yields of mineralization for organic P in the steady state grasslands of Z. japonica and M. sinensis were 0.407 and 0.504g/m2, respectively." |
