Análise foliar em cinco espécies de eucaliptos

Abstract: Foram coletadas 200 folhas recem maduras de meia altura (H = 11 m) da copa das espécies E. graandis, E. microcorys, E. saligna de sete anos de idade, localizadas em solo latossolo, na região de Mogi Guaçu e Areia Branca, SP. As folhas foram analisadas para N, P, K, Ca, Mg, S, B, Cu, Fe, Mn e Zn com os objetivos de detectar exigências nutricionais distintas para as espécies, assim como correlacionar o teor dos nutrientes com o volume cilíndrico de madeira (m³/ha). Constatou-se diferenças significativas na compo… Show more

“…Nevertheless, it should be considered the possible differences between adequate levels of nutrients for each eucalyptus species, as presented by Millner & Kemp (2012). The authors conducted a study in New Zealand with different species of eucalyptus to determine nutrient content in leaf tissue in different species and sites, and found significant differences between species with values ranging from 1.14 to 1.92% of N, 0.124 and 0.193% of P, 0.57 and 0.89% of K, 0.41 and 0.75% of Ca, and 0.21 and 0.38% of Mg. Haag et al (1976) working with leaf analyses with five species of eucalyptus found values ranging from 1.41 to 2.12% of N, from 0.08 to 0.12% of P, from 0.27 to 0.48% of K, 0.27 to 0.50% of Ca, and 0.11 to 0.17% of Mg. Therefore, it could be considered the lower Ca, and Mg leaf contents as a characteristic of the species studied.…”

“…Os teores de Cu encontrados nas folhas, a partir dos doze meses, são muito inferiores aos encontrados por Haag et al (1976), em experimento com cinco espécies de eucalipto, na região de Mogi Guaçu. Os autores encontraram valores que variaram de 5 mg kg -1 para E. resinífera até 7 mg kg -1 para E. robusta, enquanto, neste experimento, os valores encontrados foram inferiores a 5 mg kg -1 .…”
