“…As espécies pioneiras, segundo Benvenutti-Ferreira et al (2009), normalmente aportam maior quantidade de serapilheira que as secundárias. É importante a presença de espécies com aportes complementares para manter-se um estoque regular de serapilheira ao longo do ano, como salientam Müller et al (2009) para em área com predominância de Schinus terebinthifolius e Jaramillo- Botero et al (2008) com Schizolobium parayba.…”

RESUMOOs objetivos deste estudo foram avaliar a deposição de serapilheira ao longo de dois anos e a qualidade nutricional da serapilheira, em função do espaçamento de plantio visando à restauração florestal. Os espaçamentos de plantio 1 × 1; 1,5 × 1,5; 2 × 2 e 3 × 2 m, constituem as unidades amostrais dos tratamentos. No espaçamento 1 × 1 m foi observada a maior deposição de serapilheira, não havendo diferenças entre as unidades dos demais espaçamentos. A fração folha mostrou, em todos os espaçamentos, maior aporte de serapilheira (77%). O maior conteúdo de nutrientes foi observado no espaçamento 1 × 1 m. Em geral, constatou-se a seguinte ordem quanto o conteúdo de nutrientes da serapilheira N > Ca > K > Mg > P.Palavras-chave: nutrição florestal, ciclagem de nutrientes, material decíduo. Litter Production and Forest Nutrients in Forest Restoration Area with Different Planting Spacing ABSTRACTThe objectives of this study were to evaluate the deposition of litter over two years and the nutritional quality of the litter, depending on the planting space aimed at forest restoration. The planting space 1 × 1, 1.5 × 1.5, 2 × 2 and 3 × 2 m, are the sampling units of the treatments. In 1 × 1 m spacing greater deposition of litter, with no differences between the units other spacings was observed. Leaf fraction showed, in all spacings, greater intake of litter (77%). The higher nutrient content was observed in the 1 × 1 m spacing. In general, was observed the following order as the nutrient content of litter N> Ca> K> Mg> P.

“…The native pioneer species showed more accelerated growth in height and diameter at ground level than the non-pioneer species (Benvenuti-Ferreira et al, 2009;Carnevali et al, 2016). The growth potential of pioneer species is restricted when cultivated in poor soils, and they are more responsive to fertilization than non-pioneer species, in which the growth stimulus provided by fertilization is less pronounced and sometimes non-existent, a tendency that in part can be attributed to slower growth (Santos et al, 2008).…”

Forest cover in areas degraded by mining is an alternative way of mitigating CO 2 concentrations in the atmosphere by fixing C in tree biomass. This study evaluated the growth and C stocks of forest cover in an area of bauxite mining with four sources of fertilizer. Height (Ht), diameter at ground level (DGL), and diameter at breast height (DBH) were determined in Anadenanthera peregrina (Ap), clonal Eucalyptus (Euc), and a mixed plantation of 16 native forest species (Nat) at 6, 18, 36, and 56 months of age. Trunk+bark volume, biomass, and C stock were also determined for these forest covers at 56 months of age. The fertilization treatments were a standard (SF) adopted by the company, SF plus organic fertilizer (OF), chemical fertilizer (CF), and OF+CF. Euc displayed greater values of Ht, DGL, and DBH under OF+CF and OF. Fertilization did not influence the Ht and DBH of Ap, but DGL was higher under OF+CF at 36 months compared to SF. The Ht values of Nat were influenced by fertilization at 18 months, with the lowest values under SF. The fertilization influenced the DGL of Nat at 36 and 56 months, which did not occur with DBH. The pioneer species had higher Ht, DGL, and DGB compared to non-pioneer species, regardless of the type of fertilization studied. Fertilization influenced the Ht and DGL of pioneer species at 18 and 36 months of age and only the Ht of non-pioneer species. The estimates of Euc biomass (255 Mg ha-1) and C stocks (120 Mg ha-1) under OF+OC were four times greater than in Ap and Nat, which showed no difference between themselves or the types of fertilization. The growth and estimates of volume, biomass, and C stocks of the forest cover were comparable to those of unmined areas. Euc had the greatest growth, biomass, and C stocks.

“…AFS increase the nutrient cycling due to growing litter production, which is related to tree aging and basal area (Bhojvaid and Timmer, 1998;Kumar, 2008). On the other hand, it should be stressed that litter production in agroforestry could change by a magnitude of 20 depending on the tree species, and the pioneer and early secondary species present the higher values (Benvenuti-Ferreira et al, 2009). Nutrient cycling is also enhanced as a function of a higher microbiological activity under AFS (Vallejo et al, 2010).…”

Agroforestry systems (AFS) are policultures with at least one tree species. These systems provide various ecosystem services, income increments and food safety. These ecosystem services include biodiversity conservation, carbon sequestration, reduction of crop diseases, increased biological controls, biological nitrogen fixation and nutrient cycling. A review of potential ecosystem services of AFS on Southern Brazil is presented. In addition, the potential of carbon uptake through conversion to AFS is estimated. The predominant AFS are agroforestry with yerba mate (Ilex paraguariensis A. St. Hil.), silvopastures, citrus and banana orchards, and the palm açaí-juçara (Euterpe edulis Mart.). Considering the conversion of conventional systems to AFS, the silvopastures present the greatest carbon sequestration potentiality due to the great area used for cattle ranching. The conversion of citrus and banana cropping also present great carbon uptake potential besides reducing fungal and bacterial diseases. Southern Brazil presents more than 15 million hectares which could be converted into silvopasture and other AFS by taking as a model the already well-established experiences. Moreover, AFS has become a strategy for forest restoration. There are no negative trade-offs related to the silvopasture and citrus agroforestry adoption. The reasons for the low adoption of AFS are discussed.
