Theoretical Analysis of the Long-Term Dynamics of Carbon and Nitrogen in Soils

摘要: Carbon and nitrogen turnover in soils having continuous inputs of litter is described using theory developed for single cohorts litter. Fresh characterized by its quality (how easily it decomposed microbes) N:C ratio. The decom- position process as a continuum no transition between humus recognized. Equations are derived the amounts carbon soil at steady state. Depending upon microbial production-to-assimilation ratio when substrate lowest (most-degraded litter) decomposed, state implies either constant or linearly increasing nitrogen. Comparisons made theoretically estimated observed relations rates large range terrestrial ecosystems, well stocks Scots pine forest soil.
