Abstract
This paper deals with carbon stock in litter and soil of the old growth Pinus roxburghii (Pine) plantation. The Pine plantation was raised in the year 1926 and due to the mortality of Pine is being replaced by some broad-leaved species, in patches, constituting four plant communities. The study of these communities, viz. Pure Pine, Pine – Michelia, Mixed Pine and Pure Cinnamomum camphora community shows that carbon content and organic carbon percentage was higher in Pine-Michelia and Mixed Pine communities than in Pure Pine and Pure C. camphora communities, therefore it may be concluded that Pine plantation mixed with broad -leaved is beneficial in carbon stock as well as organic carbon percentage, the litter of mixed Pine forest with higher base content is less acidic, less able to complex on protein and much easier to decompose than acidic litter of Pure Pine forests.
