Carbon stocks and isotopic composition of the organic matter in soils covered by native vegetation and pasture in sorocaba, Sp, Brazil
(2009-12-01)
Land cover change constitutes one of main way of alteration of soil organic matter in both quantitative and qualitative terms. The goal of this study was to compare the carbon stock and the isotopic signature of the organic ...
Organic matter redox state driven by specific sources in mangrove sediments: A case study from peruvian ecosystems
(MDPI, 2021)
In order to determine the organic matter redox state in relation to specific sources in mangrove sediments, two 60 cm-long sediment cores were collected from mangrove-covered and mudflat zones within a mangrove forest in ...
Tolerance of Brazilian brain coral Mussismilia braziliensis to sediment and organic matter inputs
(2013)
In Brazil, where reefs occur in markedly turbid environments, the relationship between sedimentation/organic matter and corals is poorly known. Thus, the ex situ effects of sediment with and without organic matter over the ...
Retention of particulate organic matter in a tropical headstream
(Springer, 2002-08-01)
Retention of particulate organic matter was investigated over a range of water discharges in pool and riffle zones of a tropical stream (Itauna Stream, São Paulo, Brazil). A closed-system leaf release and capture method ...
Biochar effect on the mineralization of soil organic matter.
(Pesquisa Agropecuária Brasileira, v. 47, n. 5, p. 665-671, 2012., 2012)
Assessment of variations in dissolved organic matter in contrasting streams in the Pampas and Patagonian regions (Argentina)
(Csiro Publishing, 2018-09)
Dissolved organic matter (DOM) is the major source of carbon in aquatic environments and may be derived from allochthonous or autochthonous sources. This study presents the first DOM characterisation in streams from two ...
Dissolved Organic Carbon and Nitrogen in Andisol for Six Crop Rotations with Different Soil Management Intensity
