| Summary: | The aim of the present was to estimate the above-ground biomass and nutrient content of
different components of Eucalyptus globulus subspecie maidenii trees. Data were collected in a four
year old plantation on clay soil in the town of Butiá, Rio Grande do Sul. A regression equation (lnY
= a + b* lnX), was used to estimate biomass production whose coefficients were calculated from
data from nine trees sampled in different diametric classes. The total above-ground biomass was 83,2
Mg ha -1 where 13; 10; 9 and 68 % were spread in the leaves, branches, bark and wood, respectively.
In the wood of the stem were found 29; 29; 40; 12,5 and 34% of above-ground biomass N, P, K, Ca
and Mg, respectively. However, in the canopy of the trees these same elements have represented 64,
56, 48,5, 32 and 39%. The bark was the component which has accumulated the bigger amount of
calcium, 55,3% of the total. |
