Primary objective of this work was to study concentration and accumulation of the micronutrients on the rubber plants, at variuns ages. Leaves, stems and branches from one year up to four years old were collected from a plantation located at the BONAL S.A. farm at Rio Branco, Brazil. The soil under the forest was classified as a heavy texture Red-Yellow Latossol. The results showed: The leaves had the highest nutrient concentration, with the exception for copper and zinc. During the fourth year, nutrient extraction per hectare was: 29.4 g B; 18.3 g Cu; 140.4 g Fe; 436.7 g Mn and 52.2 Zn. Total micronutrients were absorbed in the following decreasing order: Fe >; Mn >; Zn >; B >; Cu.Downloads
