Soil organic carbon in cropping sequences with predominance of soya bean in the argentinean humid Pampas
(Wiley Blackwell Publishing, Inc, 2020-01)
Soya bean (Glycine max (L.) Merr.) monoculture can lead to a decrease in labile fractions of soil organic carbon (SOC). This study sought to evaluate the effects of cover crops (CC), application of fertilizer, and crop ...
Estimations of primary and secondary organic carbon formation in PM2.5 aerosols of Santiago City, Chile
(Elsevier Ltd., 2009-01-16)
High concentration of fine airborne particulates is considered one of the major environmental pollutants
in Santiago, the Chilean Capital city, which in 1997 was declared a PM10 saturated zone. To date there is
no control ...
Seasonal patterns of organic matter stoichiometry along a mountain catchment
(Springer, 2016-05)
Organic matter (OM) nutrient content is expected to change as OM is transported from upstream forested reaches downstream to open land, and these changes could depend on seasonal patterns. The aim of this study was to ...
Vehicular particulate matter emissions in road tunnels in Sao Paulo, Brazil
(Springer, 2009-02)
In the metropolitan area of São Paulo, Brazil, ozone and particulate matter (PM) are the air pollutants that pose the greatest threat to air quality, since the PM and the ozone precursors (nitrogen oxides and volatile ...
Regional-scale algorithm to estimate the particulate organic carbon (POC) in inland waters using Landsat-5/TM images
(Springer, 2017-06-01)
A regional-scale algorithm was developed in order to test if the Landsat-5/TM can be used to estimate the particulate organic carbon (POC) in oligotrophic-tomesotrophic inland water. To develop the POC algorithm two ...
Dynamic modeling of organic carbon fates in lake ecosystems
(Elsevier Science, 2018-10-24)
Lakes are active processors of organic carbon (OC) and play important roles in landscape and global carbon cycling. Allochthonous OC loads from the landscape, along with autochthonous OC loads from primary production, are ...
Plant rhizodeposition: A key factor for soil organic matter formation in stable fractions
(Science Advances is the American Association for the Advancement of Science, 2021-04)
Soil organic carbon formation remains poorly understood despite its importance for human livelihoods. Uncertainties remain for the relative contributions of aboveground, root, and rhizodeposition inputs to particulate (POC) ...
