Remineralization of organic carbon in eastern Canadian continental margin sediments
(Deep-Sea Research Part II: Topical Studies in Oceanography, 2000)
Undisturbed sediment samples were collected for chemical analyses at six sites during winter and summer cruises to the eastern Canadian continental margin. Micro-electrode oxygen profiles were obtained in freshly collected ...
Estimating soil organic carbon in Mollisols and its particle-size fractions by loss-on-ignition in the semiarid and semihumid Argentinean Pampas
(Elsevier B.V., 2018-03)
Recent interest in soil quality assessment underscores the need for an accurate measurement of soil organic carbon (OC) and its labile fraction, i.e. particulate OC. The loss-on-ignition (LOI) method has been proposed as ...
Determinación de Fracción de Carbono en Suelos de bajo Bosque y Pasto

Particulate organic matter, carbohydrate, humic acid contents in soil macro- and microaggregates as affected by cultivation
(Elsevier Science, 2006-12)
Cultivation is known to strongly affect not only soil structure but also organic substances responsible for aggregation. This research was conducted to study the effect of cultivation on the distribution of soil macro- and ...
Watershed Deforestation and Down-Estuary Transformations Alter Sources, Transport, and Export of Suspended Particles in Panamanian Mangrove Estuaries
(Springer, 2014-01)
We identified eight Panamanian watersheds in which conversion from wet tropical forest to pastures differed and assessed the effects of degree of deforestation, and down-estuary transformations, on the suspended particulate ...
Particulate organic carbon is a sensitive indicator of soil degradation related to overgrazing in Patagonian wet and mesic meadows
(Springer, 2018-06)
Patagonian meadows are key for the development and sustainability of rural environments. However, they have been degraded due to a combination of weather conditions and overgrazing. Total soil organic carbon (TOC) has been ...
Sample acidification has a predictable effect on isotopic ratios of particulate organic matter along the Chilean coast
(2019)
Rationale Stable isotopes of carbon and nitrogen have proved to be valuable tools for researchers working across the different subfields of ecology. However, the chemical pretreatment of samples prior to analytical ...
Continuous Wheat in Semiarid Regions: Long-term Effects on Stock and Quality of Soil Organic Carbon
(Lippincott Williams, 2014-06)
Continuous wheat (Triticum aestivum L.) cropping in semiarid regions results in variable dry matter production. As a consequence, the balance of soil organic carbon (SOC) may vary across time. The aim of this research was ...
Characterization of urban aerosol in Campinas, Sao Paulo, Brazil
