A study on assessment of total soil organic carbon in teak ecosystem in humid tropics was done using a soil carbon model, CENTURY. The objectives of the study included the evaluation of suitability of this model in teak ecosystems and to analyse the of total soil organic carbon simulated by this model. The study was conducted based on secondary data sets collected from the experiments done in teak plantations of Thrissur district. The other data sets related to soil parameters were collected from various resources of Kerala Agricultural University and Kerala Forest Research Institute. Soils in natural forest were used as a baseline to compare the soil in teak plantations. Hence any variation in soil conditions can be considered as a result of various management operations carried out on these natural forests and based on 1965 to 2050 year time sequence, it was reconstructed. The net primary productivity prediction by the model was taken as an accuracy index for other model outputs represented at those sites. The simulated carbon values were compared with the carbon baseline data obtained from different aged teak plantations. For CENTURY model, site data, site specific parameters, Event.100 file and schedule files were used. Hence it was concluded that for simulation of soil organic carbon, CENTURY model was efficient and it predicted a declining trend of total soil organic carbon. The model efficiency of CENTURY models for teak ecosystem was 0.88.
