“…O mesmo ocorre com relação a M. scabrella, segundo Baggio & Carpanezzi (1997), e a A. mangium (Garay et al, 2004) (Tabela 1). Em todos os tratamentos, apenas o consórcio entre E. grandis e M. scabrella apresentou maior acúmulo de N na soma de todos os seus compartimentos em relação ao povoamento solteiro de E. grandis (Figura 3).…”

Resumo -O objetivo deste trabalho foi avaliar o crescimento inicial da parte aérea e do sistema radicular, a nutrição mineral e a fixação biológica de N 2 (FBN Growth, nutrition and biological fixation of nitrogen in mixed-species plantations of eucalypt with leguminous treesAbstract -The objective of this work was to assess interactions between species on the above and belowground growth, nitrogen uptake and biological nitrogen fixation (BNF) in mixed stands of Eucalyptus grandis and native leguminous N 2 -fixing trees. A complete randomized block design was installed with seven treatments and three blocks. Within the lines of the E. grandis seedlings, native leguminous N 2 -fixing trees -Peltophorum dubium, Inga sp., Mimosa scabrella, Acacia polyphylla, Mimosa caesalpiniaefolia -and one exotic leguminous plant, Acacia mangium, were intercropped. E. grandis was also solely planted. Mimosa scabrella and A. mangium were the legume trees that presented the highest growth. Although E. grandis showed a lower growth when combined with M. scabrella, this mixed-species stand exhibited the highest biomass accumulation. Eucalyptus grandis fine root densities (FRD) were 6-20 times higher than the FRD of the leguminous species in the upper soil layer (0-10 cm) 24 months after planting. The FRD of M. scabrella and M. caesalpiniaefolia in the 30-50 cm soil layer was higher than in the 10-30 cm layer. The δ 15N values of M. scabrella indicated that 90% of stocked N is derived from BNF.

“…At BM3, the great richness of planted species may have affected the regeneration results, because it facilitates the entrance of light, filtrates radiation by alternation of their deciduous caducifoly period, modifying the soil physical-chemical conditions, improving the regeneration process. Studies with planted species at the Cerrado site indicated different soil properties according to the litter composition (GARAY et al, 2004).…”

The analysis of species composition and its effects on sustainability restoration processes in the Atlantic Forest with poor environmental attributes is important to improve rehabilitation techniques for disturbed ecosystems. Reforestation projects were used as Biological Measures (BM) of rehabilitation, where treatments differ in the composition of exotic species, utilized as anthropic pioneers: BM1 - 82% (73% Mimosa caesalpiniifolia Benth, 9% Eucalyptus citriodora Hook.); BM2 - 91% (9%, 82%); and BM3 - 25% (15%, 10%). The monitoring of spontaneous regeneration was evaluated in three 12-year-old reforestation sites between thr rainy season of 2004 and 2005, and compared with an approximately 100-year-old native forest fragment and a grassland: ecosystems with inertial tendency toward recuperation and degradation, respectively. It was detected that exotic species used as anthropic pioneers strongly influenced regeneration: BM1 (75%), BM2 (85%), BM3 (55%), Forest (0%) and Grassland (50%). The highest similarity of species with forest regeneration (5%) was found for treatment BM3.

“…Due to its rapid initial crown development and tolerance of very poor soil, A. mangium can effectively suppress Imperata grasses (Awang and Taylor 1993, Tilki and Fisher 1998, Turnbull et al 1998) and provide a favorable condition for the growth of slow-growing tree species (Norisada et al 2005, Otsamo 2000, Yang et al 2009). Also the establishment of A. mangium plantations has beneficial effects on the stands such as increase in availability of soil nutrients, especially N (Bernhard-Reversat 1996, Franco and DeFaria 1997, Garay et al 2004, Inagaki et al 2010, Li et al 2001, Majalap 1999, Schiavo et al 2009, Yang et al 2009) and improvement of soil structuration (Garay et al 2004, He et al 2007.…”

Nutrient inputs via litterfall and associated nutrient accumulations and releases in the litter layer were investigated in 7-year-old Acacia mangium Willd. plantation stands in Indonesia. Annual N, Mg, Ca and K inputs via litterfall were 230-235, 21-26, 157-179 and 131-157 kg ha 1 yr 1 , respectively and the contributions of phyllode litterfall to these nutrient inputs were over 60 %. Nutrient inputs via litterfall increased from dry to wet seasons being strongly associated with reproductive litterfall inputs as well as phyllode litterfall inputs. Annual mean N, Mg, Ca and K accumulations on the forest floor were 172-235, 12-14, 52-88 and 42-47 kg ha 1 , respectively. There were no clear seasonal variations in nutrient amounts on the forest floor. The peak of mass loss of phyllode litter was observed in the late wet seasons, and its seasonal change was coincided with the rainfall seasonality. Reflecting mass losses of reproductive and twig litters, however, seasonal variability in mass loss of whole litter became more complex. Nitrogen and Mg releases from litter layer tended to increase in the late wet seasons being affected by the retarded releases of these nutrients from fleshly fallen litters in addition to the increased mass loss of phyllode litter in the periods. Calcium releases from litter layer showed no significant seasonal variations reflecting the irregular seasonal changes in Ca release from twig litter rich in Ca. Meanwhile, the seasonal variation in K release from litter layer coincided with the seasonal changes in K inputs via litterfall.
