Nitrification inhibitor addition to farm dairy effluent to reduce nitrous oxide emissions
(Sociedade Brasileira de Ciência do Solo, 2024-03)Increasing the use of nitrogen (N) fertilizers will be necessary to enhance grain and pasture yields to satisfy the growing world demand for food. Organic amendments, such as farm dairy effluents (FDE), are an alternative ... -
Nitrogen–sulfur fertilisation effects on gluten composition and industrial quality in Argentinean bread wheat cultivars differing in apparent sulfur recovery
(CSIRO, 2021-03-12)Increasing wheat yield and grain quality is crucial for achieving profitable production systems. Genotype has an important role in determining potential grain end-use quality, because it defines the protein subunits stored ... -
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. ... -
