Distribution of Nutrient in an Age Series of <I>Eucalyptus globulus</I> Platation in Tamil Nadu

Abstract

The distribution of nutrients in six blue gum (E. globulus) plantations of different ages growing in Tamil Nadu bas been discussed. As a result of harvesting tbe bole (59% of total biomass) only at the age of 7 years will result in the removal of nearly 44% (N and P), 29% (K) 7% (Ca) and 24% (Mg). The same plantation when harvested at the age of 16 years with a bole biomass of 74.3% will cause the removal of 55% of N, 65% of P. 22% of K, 13% of Ca and 27% of Mg.
