Background & Aim: The magnitude of litter fall and its decomposition in a forest ecosystem impart a crucial role innutrient supply to plant as well as microorganisms. The present study was conducted to evaluate and compare thelitter fall production, leaves litter decomposition and nutrient re-translocation among the dominant species i.e. Pineand Oak, of temperate forest of Kumaun region. Results: The estimated annual litter fall production was significantly23% higher in Pine stand than Oak stand. The maximum portion of litter fall was occurred in summer and dry periodbetween April-June. The nutrients concentration was higher in green leaves than leaves litter. Additionally, thenutrients concentration was found to be high in green leaves as well as in leaves litter of Oak species. Thedecomposition rate of leaves litter was found to high in Oak floor which is inversely proportional to the C/N ratio.The nutrient immobilization for all the nutrients was found to be high in Pine stand. The nutrient re-translocationpercentage were in the order of P > K > N > Ca, in both the species that indicates the higher immobilization ofphosphorous and potassium in the region. Soil status is also responsible for litter decomposition. The soil MBC,MBN, MBP, basal respiration and enzymes activity were higher in Oak stand which is directly correlated with thedecomposition rate. Conclusions: Our results suggested that different plant species growing in same climaticcondition differed in litter fall, litter decomposition and have different level of nutrients uptake and availability
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
