Nitrous oxide emission after the addition of organic residues on soil surface
(Elsevier, 2017)The addition of organic amendments with a low Carbon:Nitrogen (C:N) ratio to restore degraded soils may increase the emission of greenhouse gases and affect the storage of these elements in the topsoil. Our objectives were ... -
Nitrous oxide emission estimation from managed soils in Argentina: Differences between IPCC 2006 guidelines and the IPCC 2019 refinemet
(Facultad de Agronomía, Universidad de Buenos Aires, 2022-10-01)Based on the IPCC 2006 guidelines, the total GHG emission for 2016, in Argentina, were estimated to reach a total net 364 MtCO2eq. Particularly, N2O emissions from managed soils sector represented 12% of total emissions. ... -
Nitrous oxide emissions from a typical argiudol soil with organic and chemical amendments = Emisiones de óxido nitroso desde un suelo argiudol típico con enmiendas orgánicas y químicas
(Asociación Argentina de la Ciencia del Suelo, 2022-06-01)Diversification in fertilizer sources will be necessary to meet the growing demand for food worldwide. For this reason, organic amendments emerge as a synthetic fertilizers alternative. Composting organic waste stabilizes ... -
Nitrous oxide emissions in corn (Zea mays L) as affected by timing, method of application and source of dairy manure.
(2016)Field trials were conducted during three years to evaluate the effect of timing, method of application and manure source on N2O emissions and corn grain yield at Elora, ON, Canada. A randomized block design was set up every ... -
Nitrous oxide emissions in maize on mollisols in the Pampas of Argentina
(Elsevier, 2021-01-14)The objectives of this study were i) to measure the soil N2O fluxes in a cropping system currently adopted by farmers of the region (FP), and in an ecologically intensified cropping system (EI) over two consecutive maize ... -
Reutilizar purines de tambo como oportunidad para reciclar nitrógeno y reducir su impacto ambiental
(Asociación Argentina de Ecología, 2023-08)Los purines de tambo (excretas mezcladas con agua de las instalaciones de ordeñe) se pueden reutilizar en la producción agrícola como reemplazo de los fertilizantes sintéticos. Sin embargo, su alta concentración nitrogenada ... -
Riparian buffer strips influence nitrogen losses as nitrous oxide and leached N from upslope permanent pasture
(Elsevier, 2022-05-23)Riparian buffer strips can have a significant role in reducing nitrogen (N) transfers from agricultural land to freshwater primarily via denitrification and plant uptake processes, but an unintended trade-off can be elevated ... -
Soil carbon dioxide and nitrous oxide emissions during the growing season from temperate maize‐soybean intercrops
(Wiley, 2012-06)The Argentine Pampa is one of the major global regions for the production of maize (Zea mays L.) and soybean (Glycine max L. [Merr.]), but intense management practices have led to soil degradation and amplified greenhouse‐gas ... -
Soil nitrous oxide emissions from Eucalyptus plantation in Argentina
(Elsevier, 2020-10-01)Nitrous oxide has a key effect on global climate development and 53% of N2O total annual emissions are related to fluxes from the soil. Land use and soil characteristics affect N2O emissions. There are not enough assessments ... -
Soybean in rotation with cereals attenuates nitrous oxide emissions as compared with soybean monoculture in the Pampas region
(Elsevier, 2021-11)Nitrous oxide (N-N2O) emissions in the agricultural sector represent ca. 25% of total N-N2O emissions on a global scale. In Argentina, information on agricultural emissions is scarce, and thus, N-N2O emissions are estimated ... -
Spontaneous Mutations in the Nitrate Reductase Gene napC Drive the Emergence of Eco-friendly Low-N2O-Emitting Alfalfa Rhizobia in Regions with Different Climates
(Springer, 2020)We have recently shown that commercial alfalfa inoculants (e.g., Sinorhizobium meliloti B399), which are closely related to the denitrifier model strain Sinorhizobium meliloti 1021, have conserved nitrate, nitrite, and ... -
To burn or not to burn : the question of straw burning and nitrogen fertilization effect on nitrous oxide emissions in sugarcane
(2017)Nitrous oxide (N2O) is the main greenhouse gas emitted from farming systems and is associated with nitrogen (N) fertilizer application as well as decomposition of organic matter present in the environment. The objective ...
