Relação entre as emissões de N2O e a expressão dos genes do ciclo do nitrogênio em um solo cultivado com milho sobre resíduo de ervilhaca
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2022-02-04)
Addition legume residues as cover crops may increase soil N2O emissions under no-tillage system. However, when there is water deficit and grass cultivation in succession, the activity of denitrifying microorganisms and ...
Effect of intermittent induced aeration on nitrogen removal and denitrifying-bacterial community structure in Cork and gravel vertical flow pilot-scale treatment wetlands
(Taylor & Francis, 2021-08)
In this work, we have evaluated the impact of intermittent induced aeration in total nitrogen (TN), ammonia (NH4-N) and nitrate-nitrogen (NO3-N) removal in four pilot-scale vertical flow constructed wetlands (VFCW) (two ...
Cuantificación de genes relacionados con procesos claves del ciclo del nitrógeno en suelos antárticos con influencia de asentamientos animales
(Universidad de Chile, 2018)
El ciclo del nitrógeno es central para la biogeoquímica del planeta y presenta grandes flujos naturales desde la atmósfera hacia los ecosistemas. La biogeoquímica del nitrógeno depende casi por completo de las reacciones ...
Biochar Enhances Nitrous Oxide Reduction in Acidic but Not in Near-Neutral pH Soil
(Mdpi, 2019-12-01)
We quantified nitrous oxide (N2O) fluxes and total denitrification (N2O + N-2) in an acidic (Ferralsol) and a near-neutral pH soil (Cambisol) to determine whether biochar's alkalinization effect could be the mechanism ...
Analysis of the denitrification pathway and greenhouse gases emissions in Bradyrhizobium sp. strains used as biofertilizers in South America
(Wiley Blackwell Publishing, Inc, 2019-06)
Aims Greenhouse gases are considered potential atmospheric pollutants, with agriculture being one of the main emission sources. The practice of inoculating soybean seeds with Bradyrhizobium sp. might contribute to nitrous ...
Denitrifying community structure variability in the Colombian Pacific
(Pontificia Universidad Católica de Valparaíso, 2018)
Predominance and high diversity of genes associated to denitrification in metagenomes of subantarctic coastal sediments exposed to urban pollution
(Public Library of Science, 2018-11)
The aim of this work was to characterize the microbial nitrogen cycling potential in sediments from Ushuaia Bay, a subantarctic environment that has suffered a recent explosive demographic growth. Subtidal sediment samples ...
