“…Clearing forests and tillage practices due to many reasons discussed earlier have resulted in loss of SOC from the soil to the atmosphere. Fitzsimmons et al (2004) reported conversion of natural resources to agriculture is the biggest source of anthropogenic carbon emissions after fossil fuels.…”

“…Deforestation and intensive soil preparation for agricultural purposes are the main contributors to such emissions. Most of the native vegetation has been cleared for pasture cultivation and several investigations have addressed the effects of forest conversion to pasture on above-and belowground C stocks (Cerri et al, 1996;Silver www.elsevier.com/locate/foreco Forest Ecology and Management 235 (2006) 219-231 et al, 2000;Fitzsimmons et al, 2003). Although whole system C balance is usually negative due to the loss of forest biomass (Conant and Paustian, 2002), well managed pastures are able to maintain and even increase belowground C stocks with time (Fearnside and Barbosa, 1998).…”

“…Não obstante, Fitzsimmons et al (2004) ) não gerarem diferenças significativas de carbono a um metro de profundidade. Portanto o impacto do reflorestamento sobre o estoque de carbono do solo é mais pronunciado em solos com menos argila, associado também ao manejo, ao tipo de floresta e à rotação (PAUL et al, 2002).…”

RESUMOO crescimento das árvores e acúmulo de biomassa, bem como a manutenção do resíduo florestal na superfície do solo pode atuar na retirada de carbono da atmosfera graças ao processo de ciclagem de material vegetal. O objetivo foi estudar a influência das plantações de Eucalyptus sp. com 20, 44 e 240 meses de idade sobre a variação de carbono no solo e na biomassa. O carbono no solo foi determinado em profundidade por meio de autoanalisador CHNS e o carbono na vegetação foi determinado pela biomassa em cada floresta, considerando um fator de 0,45 da massa seca. Determinaram-se a densidade e a análise granulométrica do solo. Para a comparação entre plantações, realizou-se a análise de variância e comparação de médias do carbono na vegetação e no solo, considerando o nível de 5 % de probabilidade. O teor e estoque de carbono no solo foram baixos, indicando ser uma característica natural da categoria dos Argissolos ou que o crescimento das florestas de eucalipto em substituição à vegetação campo nativo não agregou um aumento significativo no carbono, apesar de ter ocorrido um aumento significativo de carbono na biomassa acima do solo, a qual inclui a biomassa florestal aérea e a serapilheira. Portanto, apesar dos baixos valores de estoque de carbono, identificou-se um maior estoque médio total no solo quando comparado ao estoque acima do solo. Além disso, esse aumento acima do solo (compartimentos arbóreos e serapilheira) pode ser considerado significativo entre as plantações de eucalipto com diferentes idades.

ABSTRACTThe tree growth and biomass accumulation, as well as the maintenance of forest residue at the soil surface can act in the removal of carbon from the atmosphere through the cycling process of plant material. The objective was to study the influence of Eucalyptus sp. Plantations with 20, 44 and 240 months of age on the variation of carbon in soil and biomass. The carbon in the soil depth was determined by CHNS auto-analyzer and carbon in the vegetation was determined by the biomass in each forest, considering a factor of 0.45 of the dry mass. We determined the density and particle size distribution of soil. For the comparison between plantations, there was analysis of variance and comparison of means of carbon in vegetation and soil, considering the 5 % level of probability. The carbon content and stock in the soil were low, indicating that a natural feature of the category of Paleuldt, or the growth of eucalyptus forests, replacing the field native vegetation did not aggregate a significant increase in the carbon. Although, there was a significant increase carbon in aboveground biomass. It includes forest biomass and litter. So, despite the values of carbon stocks are low, it identified a greater average total in the soil compared to the stock aboveground. Furthermore, this 1.
