Characterization of nicosulfuron availability in aged soils
(AMER CHEMICAL SOC, 2008)
Sorption-desorption interactions of pesticides with soil determine their availability for transport, plant uptake, and microbial degradation. These interactions are affected by the physical-chemical properties of the ...
Evidence for a correlation between total lead concentrations in soils and the presence of geological faults
(2017-09-01)
The emission of radon gas in regions of geological faults, during the radioactive decay of uranium and thorium, results in the formation of lead isotopes 210Pb, 208Pb, 207Pb and 206Pb. As a consequence, the lead contamination ...
Propiedades de la fertilidad de un suelo cañero bajo diferentes tipos de gestión orgánica y convencional
(2018)
La caña de azúcar es uno de los principales cultivos producidos en Brasil, desde los tiempos coloniales. La gestión del suelo en el cultivo de la caña ha sufrido cambios en el tiempo, con la aplicación de nuevas técnicas ...
Chemical variables influencing microbial properties in composted tannery sludge-treated soil
(Springer, 2018-08-01)
Repeated applications of composted tannery sludge to arable soils have the potential to greatly alter soil chemistry and thus potentially influence the soil microbial community over time. This study performed multivariate ...
Tree species composition and environmental relationships in a Neotropical swamp forest in Southeastern Brazil
(2008-12-01)
We examined the relationships between topography, soil properties and tree species composition in a Neotropical swamp forest in southeastern Brazil. Plots were sampled in the forest, encompassing three different soil ground ...
Combined effects of litter features, UV radiation, and soil water on litter decomposition in denuded areas of the arid Patagonian Monte
(Springer, 2016-09)
Aims: We evaluated the combined effects of litter type, UV radiation, and soil water on litter decomposition processes in denuded areas of the arid Patagonian Monte. Methods: We conducted a manipulative experiment with ...
Rainfall chemistry composition in two ecosystems in the northeastern Brazilian Amazon (Amapa State)
(Amer Geophysical UnionWashingtonEUA, 2000)
Physical and chemical matrix effects in soil carbon quantification using laser-induced breakdown spectroscopy
(2014)
Advanced field methods of carbon (C) analysis should now be capable of providing repetitive, sequential measurements for the evaluation of spatial and temporal variation at a scale that was previously unfeasible. Some ...
Tungsten permanent chemical modifier for fast estimation of Se contents in soil by graphite furnace atomic absorption spectrometry
(Amer Chemical Soc, 2003-07-02)
A tungsten carbide coating on the integrated platform of a transversely heated graphite atomizer was used as a modifier for the direct determination of Se in soil extracts by graphite furnace atomic absorption spectrometry. ...
Land use change alters the radiocarbon age and composition of soil and water-soluble organic matter in the Brazilian Cerrado
(2019-07-01)
The Brazilian Cerrado has undergone extensive land-use change in the past century with large areas converted to agriculture and silviculture. Eucalyptus is the dominant planted tree species in Brazil, but the short rotations ...
