Biomass and Nutrient Distribution in an Age Series of Eucabyptus Hybrid Plantation in Tamil Nadu I. Distribution of Organic Matter

The distribution of organic matter in an age series of Eucalyptus Hybrid plantation. In Tamil Nadu has been discussed . It was observed that (i) the rotation age for E. hybrid can be fixed at 7 years where the mean Annaual Production (MAP) is at the maximum,(ii) Pollachi seems to be comparatively better site for E. hybrid planting presumbly due to higher leaf efficiency and (iii) to increase the productivity in a coppicied crop thinning is essential as the lower stand density gives a better chance for high leaf production and consequently higher biomass.
