Abstract

Observations on above ground litter decomposition and nutrient release in alpine ecosystem of the Himalaya were carried out. Monthly variation was observed for above ground litter crop and it was higher in the protected sites (PR) when compared with unprotected sites (UNPR). Turnover rate (TR) and time (TT) was also higher in PR sites and it corresponded to maximum net accumulation of standing dead and litter biomass. This resulted into low litter disappearance and therefore, low nutrient fluxes as well. Comparatively, potassium content was a maximum followed by N and OC in above ground crop of litter with significant variation among the sites (P
