Las actividades agropecuarias se han asociado con el incremento de óxido nitroso hacia la atmósfera, por prácticas de manejo (fertilización y mecanización) que contribuyen con la dinámica del nitrógeno, las cuales limitan el almacenamiento del metano (CH4). Sin embargo, los sistemas agrícolas se ...

Flujo acumulado de gases de efecto de invernadero para cuatro sistemas productivos del trópico colombiano
Small-scale spatial variability in soil carbon dioxide (CO2) and nitrous oxide (N2O) fluxes poses serious challenges to the experimental design, and number of gas samples needed to provide a reliable estimate of flux usually exceeds analytical capacities. We pooled gas samples –analogously to soi...

New records of very high nitrous oxide fluxes from rice cannot be generalized for water management and climate impacts
There has been much debate about the uncertainties associated with the estimation of direct and indirect agricultural nitrous oxide (N2O) emissions in developing countries and in particular from tropical regions. In this study, we report an up-to-date review of the information published in peer-r...

Direct Nitrous Oxide Emissions From Tropical And Sub-Tropical Agricultural Systems - A Review And Modelling Of Emission Factors
Increasing demand for food and fibre by the growing human population is driving significant land use (LU) change from forest into intensively managed land systems in tropical areas. But empirical evidence on the extent to which such changes affect the soil-atmosphere exchange of trace gases is st...

Quantifying the contribution of land use to N2O, NO and CO2 fluxes in a montane forest ecosystem of Kenya
Peat soils can be strong sources of atmospheric nitrous oxide (N2O), but at the same time act as sinks for the greenhouse gas N2O. However, the role of N2O reduction to dinitrogen (N2) here is still not fully understood. In particular, this applies to pristine or weakly disturbed fen mires. These...

The objective of this work was to measure the fluxes of N2O‑N and NH3‑N throughout the growing season of irrigated common‑bean (Phaseolus vulgaris), as affected by mulching and mineral fertilization. Fluxes of N2O‑N and NH3‑N were evaluated in areas with or without Congo signal grass mulching (Ur...
