Influence of Climatic Factor on the Carbon and Nitrogen Content in the Leaf Litter Biomass of Subtropical Ecosystem, North East India

The study about leaf litter is crucial for the study of nutrient input to the soil that contributes significantly to the nutrient cycle dynamics and stability of the existing ecosystem. It is of utmost importance to study the variation of carbon (C) and nitrogen (N) content in the leaf litter biomass as an influence by the seasonal variability of climate. Besides, the tropical forest has been experiencing the warming climate that influences the carbon cycle. In the present investigation, the estimated total annual litter biomass carbon was found as 54.88 g C m-2 yr-1 to 225.26 g C m-2 yr-11. The nitrogen content ranges from 9.37 0.04 mg g-1 to 15.27 0.21 mg g-1. The leaf litter N and C as well as with the climatic factors were significantly correlated in all the studied grove. This study reveals that regional variability of leaf litter nutrient content is influenced by the warming climate that results in faster C cycle.
