The current expansion of the oil palm (Elaeis guineensis Jacq.) in the Brazilian Amazon has mainly occurred within smallholder agricultural and degraded areas. Under the social and environmental scenarios associated with these areas, oil palm-based agroforestry systems represent a potentially sustainable method of expanding the crop. The capacity of such systems to store carbon (C) in the soil is an important ecosystem service that is currently not well understood. Here, we quantified the spatial variation of soil C stocks in young (2.5-year-old) oil palm-based agroforestry systems with contrasting species diversity (high vs. low); both systems were compared with a ~10-year-old forest regrowth site and a 9-year-old traditional agroforestry system. The oil palm-based agroforestry system consisted of series of double rows of oil palm and strips of various herbaceous, shrub, and tree species. The mean (±standard error) soil C stocks at 0?50 cm depth were significantly higher in the low (91.8 ± 3.1 Mg C ha−1) and high (87.6 ± 3.3 Mg C ha−1) species diversity oil palm-based agroforestry systems than in the forest regrowth (71.0 ± 2.4 Mg C ha−1) and traditional agroforestry (68.4 ± 4.9 Mg C ha−1) sites. In general, no clear spatial pattern of soil C stocks could be identified in the oil palm-based agroforestry systems. The significant difference in soil carbon between the oil palm area (under oil palm: 12.7 ± 2.3 Mg C ha−1 and between oil palm: 10.6 ± 0.5 Mg C ha−1) and the strip area (17.0 ± 1.4 Mg C ha−1) at 0?5 cm depth very likely reflects the high input of organic fertilizer in the strip area of the high species diversity oil palm-based agroforestry system treatment. Overall, our results indicate a high level of early net accumulation of soil C in the oil palm-based agroforestry systems (6.6?8.3 Mg C ha−1 year−1) that likely reflects the combination of fire-free land preparation, organic fertilization, and the input of plant residues from pruning and weeding.

No Brasil, o Pantanal está dividido em 11 sub-regiões, sendo a Nhecolândia a segunda maior em extensão de área. A imensa maioria de seu território está situada dentro do município de Corumbá. De acordo com dados da literatura, nesta sub-região observa-se uma sucessiva freqüência de contrastes altimétricos de dois a cinco metros. Esses contrastes estão entre o topo das parte altas denominadas regionalmente de cordilheiras, que podem ser formadas por cerradão, cerrado, vindo a seguir as áreas de campo limpo, os campos alagáveis (baixadas) e os corpos d'água (baías e salinas). Com o objetivo de verificar essas diferenças altimétricas e o comportamento da vegetação foi feito um experimento na fazenda Nhumirim, no ano de 2002. |
