Última Oxidizable fractions of soil organic carbon in Caatinga forest submitted to different forest managements Ciência Rural Batista,Suellen Gomes Monteiro; Barreto-Garcia,Patrícia Anjos Bittencourt; Paula,Alessandro de; Miguel,Divino Levi; Batista,Willyan Charles Amaral. ABSTRACT: One of the main alternatives for the rational exploitation of the Caatinga biome’s natural resources is sustainable forest management. Soil organic carbon (SOC) and its fractions can be used to evaluate the conservation status of forest ecosystems after anthropic interventions. Therefore, the objective of this study was to evaluate the short-term effect of different forest management practices on the distribution of SOC fractions in the Caatinga area located in Contendas do Sincorá National Forest (BA). Three forest management practices (clear cutting, selective cutting by diameter and selective cutting by species) were evaluated, using the unmanaged Caatinga as a control. Soil samples were collected at the 0-10cm depth. The SOC was fractionated... Tipo: Info:eu-repo/semantics/article Palavras-chave: Organic matter; Chemical fractionation; Labile carbon.

ABSTRACT: There is a large number of studies evaluating methods to quantify biomass for the genus Pinus in different regions of Brazil. However, knowledge about this subject in the Northeast region of Brazil is still incipient. The objective of the present study was to assess the biomass and carbon stocks and select mathematical models to estimate these variables in Pinus caribaea var. hondurensis , which is established in homogenous stands in the Southwest region of the state of Bahia (Brazil). The biomass was quantified using the destructive method. Samples of needles, bole, bark, and branches were analyzed to determine their carbon contents. Ten models were tested, and the best of them were chosen based on the following statistical indicators: adjusted...
