“…because both presented higher leaf fall; however, higher contents of N occurred in the green and senescent leaves of the Fabaceae Senna macranthera (Colladon) Irwin and Barneby. The lack of differences between the monospecific plantations of Fabaceae and nonFabaceae species regarding N availability in the soil was also verified in northwestern Costa Rica (Gei & Powers, 2013).…”

ABSTRACT.Internal retranslocation is an important mechanism for nutrient conservation in plants, which depends on different factors. However, there are little data about this subject, especially on tropical forest species. This study aimed to evaluate the macronutrient retranslocation dynamic and the influence of ecological (P: pioneer x NP: non-pioneer) and phenological (ND: non-deciduous x D: semideciduous / deciduous) characteristics on the macronutrient content of leaves of five tree species on monospecific plantations in the Brazilian Amazon: Acacia mangium Willd., Parkia decussata Ducke, Dipteryx odorata (Aublet) Willd., Jacaranda copaia (Aubl.) D. Don and Swietenia macrophylla King. Photosynthetically active green leaves and senescent leaves (leaf litter) were collected. Retranslocation was estimated through an equation proposed by Attiwill, Guthrie and Leuning (1978). The pioneer species presented higher foliar contents of N; the non-pioneer species presented higher contents of K, Ca and S; and the results were inconclusive for P and Mg. The deciduous species presented higher foliar contents of K and of P, whereas the foliar contents of N, Ca, Mg and S were virtually identical between the phenological groups. The internal retranslocation of foliar nutrients in pioneer and non-deciduous species was higher than that of nonpioneer and deciduous species.Keywords: ecological groups, litterfall, nutrient cycling, phenological groups, plant nutrition. Retranslocação de nutrientes em espécies florestais na Amazônia Brasileira RESUMO.A retranslocação interna é um importante mecanismo de conservação de nutrientes nas plantas, que depende de diferentes fatores. Contudo, ainda são incipientes os dados desta natureza, principalmente para espécies florestais tropicais. O presente trabalho objetivou avaliar a dinâmica de retranslocação de macronutrientes e a influência dos grupos ecológico (P: pioneiras x NP: não-pioneiras) e fenológico (ND: não-decíduas x D: semidecíduas / decíduas) nas concentrações foliares de macronutrientes em cinco espécies arbóreas em monocultivo na Amazônia brasileira: Acacia mangium Willd., Parkia decussata Ducke, Dipteryx odorata (Aublet) Willd., Jacaranda copaia (Aubl.) D. Don e Swietenia macrophylla King. Para tanto, foram coletadas folhas verdes fotossinteticamente ativas e folhas da serapilheira. A retranslocação foi estimada segundo a equação de Attiwill, Guthrie e Leuning (1978). As espécies pioneiras apresentaram maiores concentrações foliares de N; as não-pioneiras apresentaram maiores concentrações de K, Ca e S; e os resultados foram inconclusivos para P e Mg. As concentrações foliares de K e de P foram maiores nas espécies decíduas, enquanto que as de N, Ca, Mg e S foram praticamente idênticas entre os grupos fenológicos. No geral, as espécies pioneiras e as não-decíduas foram mais eficientes na retranslocação de nutrientes.Palavras-chave: grupos ecológicos, serapilheira, ciclagem de nutrientes, grupos fenológicos, nutrição de plantas.

“…We predicted that soil moisture would track precipitation seasonally and correlate with fine root and nodule mass, and that nodule mass would scale positively to fine root mass. In a previous study we found large differences in soil properties and biogeochemistry among legume species in these plantations (Gei and Powers 2013), thus we hypothesized that surface fine root mass and nodulation would also differ among legume tree species.…”

“…In G. sepium, which typically contained multiple stems, single stem mean diameter was 17.4±3.6 cm. In a previous study we documented soil characteristics in these plantations (Gei and Powers 2013; Table 1). The understory vegetation mostly consists of grass that is regularly cut or managed with cattle grazing.…”

Background Fine roots comprise a dynamic carbon pool in forests. Legumes, widespread in the tropics, have a specialized strategy of nitrogen acquisition. However, the belowground dynamics of this group are poorly understood. Scope We studied the seasonal and spatial variation in surface fine root mass (FRM) and nodulation over 2 years in plantations of four legume species (Dalbergia retusa, Enterolobium cyclocarpum, Gliricidia sepium, Leptolobium panamense) in a dry forest in Costa Rica. We measured soil moisture, FRM, and nodule mass at 2 soil depths (0-15 and 15-30 cm) and at 2 distances from the tree bole (1 and 2 m). Mean FRM per species ranged from 10 to 17 g m −2 during the dry season to 86-116 g m −2 the following wet season. Species differed in belowground foraging strategies: G. sepium and L. panamense had~41 % more roots in the surface layer, but in D. retusa plantations, 44.3 % more roots were in the deeper layer. In G. sepium and L. panamense, nodulation fluctuated seasonally, while the other species did not nodulate. Conclusions FRM varied in synchrony with rainfall and responded to interannual precipitation anomalies. Thus, FRM is a sensitive component of the forest carbon pool, vulnerable to shifts in species composition and climate regimes.

“…Com esse objetivo, a arborização de pastagens, em particular com leguminosas arbóreas fixadoras de N 2 , visa minimizar os impactos ambientais da pecuária e incrementar a qualidade do solo (Dias et al, 2006). Esse grupo vegetal influencia e é influenciado pelas propriedades do solo e pela produtividade do ecossistema (Gei & Powers, 2013;Binkley & Fisher, 2013), pois contribui na manutenção dos diferentes serviços ambientais providos pela serrapilheira e pela matéria orgânica do solo e promove as interações ecológicas do ecossistema (Duarte et al, 2013).…”

RESUMOO trabalho foi desenvolvido em uma área de pasto abandonada revegetada com leguminosas arbóreas. Localizada no município de Valença, RJ, nela foram utilizadas diferentes proporções de leguminosas arbóreas fixadoras de nitrogênio: 0% (0L), 25% (25L), 50% (50L) e 75% (75L). Para avaliação da macrofauna do solo, as amostragens foram feitas nas épocas seca e úmida, utilizando-se o método TSBF. Outras amostragens foram realizadas, ainda, em uma floresta secundária (FS) e em duas áreas de pasto (PA e PB). O processo de revegetação aumentou a diversidade da fauna do solo de uma forma geral. Formicidae foi o grupo da macrofauna de maior abundância em todas as áreas, para as duas épocas de avaliação. Na época chuvosa, houve aumento considerável na quantidade de invertebrados na camada serapilheira nos tratamentos 0L, 25L, 50L, 75L e Floresta Secundária, o que no período seco aconteceu na camada 0-10 cm.Palavras-chave: invertebrados do solo, indicadores biológicos, qualidade do solo. Soil Macrofauna as Indicators in Tree Legume Revegetation ABSTRACTThe study was conducted in an area of abandoned pasture located in the city of Valença (RJ) revegetated with tree legumes. Different proportions of nitrogen-fixing leguminous trees were used: 0% (0L), 25% (25L), 50% (50L) and 75% (75L). For evaluation of soil biota, samplings were made in the end of the dry season and in the rainy season. Samples were collected in the abandoned pasture, in a secondary forest, and in two grassland areas (PA and PB). The process of reforestation has increased the overall diversity of soil fauna. Formicidae was the group that stood out, being abundant in all treatments and in the two periods of collection. During the rainy season, a considerable increase in the amount of invertebrates in the litter layer was observed in the treatments 0L, 25L, 50L, 75L and in the secondary forest, while during the dry season, such increase occurred in the 0-10 cm layer.
