“…Various authors have proved that bark is the tree component with the highest concentrations of Ca. For example, Sharma and Pande [30] found this to be the case in hybrid Eucalyptus in 5 and 7 years old stands, and in Acacia auriculiformis in 3, 5, 7 and 9 years old stands; Campos [9] in Ilex paraguariensis (12 years); Leles et al [16] in Eucalyptus camaldulensis and Eucalyptus pellita (4.3 years); Pereira et al [22] in Acacia mearnsii (9 years); and Vezzani [35] in Acacia mearnsii (3.7 years).…”

-The present study deals with the quantification of the nutrient content of the Australian acacia (Acacia mearnsii De Wild.), provenance Bodalla, at the age of 28 months. The experiment is located at a site of low fertility of the AGROSETA company in Butiá, Rio Grande do Sul (Brazil). Above-ground biomass components (leaves, living branches, dead branches, bark and wood) of nine sampled trees were analysed. The nutrient contents in the total biomass of Bodalla were 182 kg ha -1 of N, 8.17 of P, 104 of K, 66.7 of Ca, 16.2 of Mg, and 10.1 of S. In total, 42.6% of the dry matter accounted for leaves and living and dead branches, which in turn account for 74% of N, 72% of P, 63% of K, 68% of Ca, 69% of Mg, and 74% of S of the above-ground biomass. In the trunk (bark and wood), which represents the remaining 57.4% of the total above-ground biomass, 26% of N, 28% of P, 37% of K, 32% of Ca, 31% of Mg, and 26% of S were accumulated.

Cette étude concerne la quantification, à l'âge de 28 mois, des nutriments dans la biomasse aérienne de l'Acacia australien (Acacia mearnsii De Wild.), provenance Bodalla. L'expérience est localisée dans un site de faible fertilité appartenant à la compagnie AGROSETA, à Butiá, Rio Grande do Sul (Brésil). Les compartiments de la biomasse aérienne (feuilles, branches vivantes, branches mortes, écorce et bois) de 9 arbres échantillons ont été analysés. Les quantités de nutriments dans la biomasse totale de Bodalla étaient de 182 kg ha -1 de N, 8,17 de P, 104 de K, 66,7 de Ca, 16,2 de Mg et 10,1 de S. Au total, 42,6 % de la matière sèche était composée de feuilles et de branches vivantes et mortes, représentant 74 % de N, 72 % de P, 63 % de K, 68 % de Ca, 69 % de Mg, et 74 % de S par rapport à la biomasse aérienne totale. Dans le tronc (écorce et bois), qui représente les 57,4 % restant de la biomasse aérienne totale, se sont accumulés 26 % de N, 28 % de P, 37 % de K, 32 % de Ca, 31 % de Mg et 26 % de S.

Abstract. Litterfall is one of the major pathways connecting above-and below-ground processes. The effects of climate and land-use change on carbon (C) and nutrient inputs by litterfall are poorly known. We quantified and analyzed annual patterns of C and nutrient deposition via litterfall in natural forests and agroforestry systems along the unique elevation gradient of Mt. Kilimanjaro.Tree litter in three natural (lower montane, Ocotea and Podocarpus forests), two sustainably used (homegardens) and one intensively managed (shaded coffee plantation) ecosystems was collected on a biweekly basis from May 2012 to July 2013. Leaves, branches and remaining residues were separated and analyzed for C and nutrient contents.The annual pattern of litterfall was closely related to rainfall seasonality, exhibiting a large peak towards the end of the dry season (August-October). This peak decreased at higher elevations with decreasing rainfall seasonality. Macronutrients (N, P, K) in leaf litter increased at mid elevation (2100 m a.s.l.) and with land-use intensity. Carbon content and micronutrients (Al, Fe, Mn, Na) however, were unaffected or decreased with land-use intensity.While leaf litterfall decreased with elevation, total annual input was independent of climate. Compared to natural forests, the nutrient cycles in agroforestry ecosystems were accelerated by fertilization and the associated changes in dominant tree species.

“…As folhas acumularam em torno de 53% do total de N; 49% do total de P e 48% do total de S (Tabela 3), ainda que esta tenha participação percentual superior à das folhas no total da biomassa aérea (CALDEIRA, 1998 A copa (folhas, galhos vivos e mortos) acumularam em média 67,6% do total de nutrientes, no entanto os 32,4% restantes foram acumulados no fuste (madeira e casca). Vários autores (REZENDE et al, 1983;SHARMA & PANDE, 1989;REIS & BARROS, 1990;CARBONERA PEREIRA et al, 1998;CALDEIRA, 1998) verificaram que, em povoamentos florestais, a copa contém em torno de 50% da quantidade total dos nutrientes. Isto é comprovado em função do que durante a fase juvenil de um povoamento florestal, uma grande parte da alocação dos carbohidratos são canalizados para a produção de biomassa da copa.…”

RESUMONo presente trabalho foi quantificado o conteúdo de nutrientes em uma procedência australiana de Lake Geoge Bunge Dore, acácia-negra, (Acacia mearnsii De Wild.), aos 2,4 anos de idade. Esse material encontra-se estabelecido em solos de baixa fertilidade, com acidez elevada, localizado na Fazenda Menezes, no Distrito de Capão Comprido, município de Butiá, RS. Foram selecionados um total de 9 árvores para comporem as amostras. A amostragem constituiu na individualização dos compartimentos da biomassa aérea (folhas, galhos vivos, galhos mortos, casca e madeira) visando à determinação da matéria seca e do conteúdo de nutrientes. As quantidades de nutrientes contidas na biomassa total desse material foram de 334,37 kg. de Mg e 21,43 kg ha -1 de S. Quanto a distribuição nos compartimentos, 61,07% da matéria seca foi alocada para as folhas e galhos (vivos e mortos), contento 73% do N; 72,4% do P; 64% do K; 55% do Ca, 66% do Mg e 75% do S do total existente na parte aérea. O componente fuste (casca e madeira) acumulou 27% do N; 27,6% do P; 36% do K; 45% do Ca, 34% do Mg e 25% do S.
