Resumo: | The content of macronutrients (N, P, K, Ca, Mg, and S) and nutrient redistribution were evaluated in leaves of two species, an 8 years old angiosperm (Hevea brasiliensis) and a 25 years old a gymnosperm (Pinus oocarpa), both cultivated on an eutrophic Red Brown Earth (Alfissol). Leaves were collected at three different phenological states: young, mature, senescent and from the litterfall. The nutrient content of Hevea was higher, presenting 3 to 4 times higher concentrations of N, P, K and Ca suggesting that the pine had greater capacity of producing biomass with a relatively low amount of nutrients. In Pinus oocarpa 43% ofN, 65% of P and 75% of K was transferred from old to young leaves while, for Hevea, the nutrient return was 59%> for N, 65% for P and 60% for K. |

Avaliou-se a concentração dos macronutrientes N, P, K, Ca, Mg e S nas folhas de uma angiosperma (Hevea brasiliensis) e de uma gimnosperma (Pinus oocarpa), com 8 e 25 anos de idade, respectivamente, cultivadas sobre Terra Roxa Estruturada eutrófica (Alfissolo). Avaliou-se também a redistribuição de nutrientes. Foram coletadas amostras de folhas jovens, maduras, senescentes e do folhedo. Os teores dos elementos analisados nas folhas da seringueira foram significativamente superiores aos das acículas do pinheiro, chegando a valores 3 a 4 vezes maiores para N, P, K e Ca, confirmando a elevada capacidade do pinheiro de produzir biomassa, com menor quantidade relativa de nutrientes. Para Pinus oocarpa , estimou-se que 43% de N, 65% de P e 75% de K foram redistribuídos das aciculas recém-caídas para acículas jovens. Em Hevea brasiliensis, estimou-se que 59% de N, 65% dePe 60% de K foram redistribuídos das folhas recém-caídas para as folhas jovens.
