“…Para estimação da biomassa radicular, foi assumido que esta é igual a 0,5 da biomassa área. Estimou-se o carbono presente, utilizando o fator de conversão de biomassa em carbono de 0,5 (WATSON et al, 2000a;COTTA, 2008).…”

“…possam ser comparados com os valores observados noutras partes do mundo (COTTA et al, 2008;RIBEIRO et al, 2009), os valores obtidos na área de estudo encontram-se de acordo com os observados em várias regiões temperadas e mediterrâneas (AREVALO et al, 2009;HU;WANG, 2008;KARJALAINEN, 2003). Os valores dos pinhais na área de estudo foram, no entanto, modestos quando comparados com os dos pinhais de elevada produtividade em regiões mais atlânticas de Portugal (LOPES, 2005;CORREIA et al, 2008).…”

RESUMO -Estimaram-se estoques de carbono ao nível da paisagem ao longo dos últimos 48 anos na freguesia de Deilão (4.197 ha), Distrito de Bragança, Nordeste de Portugal, com o objectivo de analisar a dinâmica do carbono sequestrado numa paisagem em transformação. Construíram-se cartas de uso do solo com base em coberturas aerofotográficas de 1958, 1968, 1980, 1992 e 2006. A classificação do uso do solo foi baseada no sistema COS2005 (Instituto Geográfico Português), sendo a estrutura da paisagem descrita por métricas da paisagem. A biomassa viva e a folhada, bem como os estoques de carbono foram estimados com base em equações de biomassa e carbono e em dados de inventários. A freguesia de Deilão apresentava sinais de abandono, com redução da área agrícola e aumento da área florestal. O carbono sequestrado aumentou de 20.572 tC em 1958 para 75.449 tC em 2006, alteração essa que corresponde a um incremento de 267% durante o período de tempo considerado. Corresponde também a uma taxa média anual de sequestro de 0,27 tC/ha/ano à escala da paisagem. As alterações recentes da paisagem na freguesia de Deilão são acompanhadas pelo aumento muito significativo do carbono fixado na paisagem.Palavras-chave: Sequestro de carbono; Alteração da paisagem; Abandono da agricultura. 1958, 1968, 1980, 1992 and 2006 LANDSCAPE CHANGES AND CARBON SEQUESTRATION IN THE DEILÃO PARISH, NORTHEASTERN PORTUGAL ABSTRACT -We estimated carbon stocks at the landscape level over the last 48 years in the Deilão Parish (4.197ha), Bragança District, Northeastern Portugal, with the purpose of analyzing carbon sequestration dynamics in this changing landscape.

Physical properties of soil and root system of cocoa, peach palm and açai in the eastern AmazonThe knowledge on the relationship between roots of crop plants and soil physical properties is very important. This article evaluates the distribution of the root systems of cocoa, palm peach and açai and their relationships with the soil physical properties. The research was carried out in an alic Yellow Latosol and root and soil samples were obtained from 10 cm to 40 cm depth. The experiment was arranged in a randomized block in the factorial design (four depth soils and three root class), with four replications. The açai root amount is twice of the palm peach and ten times more that of cacao. No difference was verified in the amount of roots of peach between the distances of the plants. The roots were collected in two distances of the plant stem in monolith samples and separated in three diameter class: < 1.0 mm, 1.0-3.0 mm e > 3.0 mm. The roots amount of the three plants was directly correlated with the coarse sand content and inversely correlated with clay content and bulk density. The large pores size was also directly correlated with the amount of cacao and açai roots in the three classes of diameter. The açai showed the most abundant root system and it the greatest number of correlations between the amount of roots and the physical properties of soil involving the three diameter root classes.

rubber tree (Hevea brasiliensis) crop may accumulate significant amounts of carbon either in biomass or in the soil. However, a comprehensive understanding of the potential of the C stock among different rubber tree clones is still distant, since clones are typically developed to exhibit other traits, such as better yield and disease tolerance. thus, the aim of this study was to address differences among different areas planted to rubber clones. We hypothesized that different rubber tree clones, developed to adapt to different environmental and biological constrains, diverge in terms of soil and plant biomass C stocks. Clones were compared in respect to soil C stocks at four soil depths and the total depth (0.00-0.05, 0.05-0.10, 0.10-0.20, 0.20-0.40, and 0.00-0.40 m), and in the different compartments of the tree biomass. Five different plantings of rubber clones (FX3864, FDR 5788, PMB 1, MDX 624, and CDC 312) of seven years of age were compared, which were established in a randomized block design in the experimental field in Rio de Janeiro State. No difference was observed among plantings of rubber tree clones in regard to soil C stocks, even considering the total stock from 0.00-0.40 m depth. However, the rubber tree clones were different from each other in terms of total plant C stocks, and this contrast was predominately due to only one component of the total
