Aporte de la fijación biológica de nitrógeno a la emisión de N2O desde el suelo con cultivo de soja = Contribution of biological nitrogen fixation to N2O emission from soil under soybean
(Asociación Argentina de la Ciencia del Suelo, 2015)El óxido nitroso (N2O) es el principal gas de efecto invernadero emitido desde el sector agrícola y su producción biológica en los suelos se genera por dos vías, la nitrificación y la desnitrificación. Recientemente el ... -
Archeology, stone tools and RIMAPS technique A quantitive characterization of use - wear traces
(Microscopy Society of America, 2020-04-28)Archaeology relies on material remains to attain a broad comprehensive understanding of humanevolution, creating undeniable challenges to the methodological field. Microscopy and image techniques have had a paramount role ... -
Aridity and overgrazing have convergent effects on ecosystem structure and functioning in Patagonian rangelands
(2018-02)Over 65% of drylands are used for grazing of managed livestock. Understanding what drives grazing effects on the structure and functioning of rangelands is critical for achieving their sustainability. We studied a network ... -
Biosolids blended with edaphic supports mimic structural and biochemical features of natural soils and foster plant biomass growth
(Elsevier, 2025-01-24)Biosolids can be blended with edaphic components to formulate customized soil mixes (Technosols), where specific nutrient levels, moisture content, and other factors are tailored to support plant growth. The aim of this ... -
Biotic and Abiotic Drivers of Topsoil Organic Carbon Concentration in Drylands Have Similar Effects at Regional and Global Scales
(Springer, 2019-11)Drylands contain 25% of the world’s soil organic carbon (SOC), which is controlled by many factors, both abiotic and biotic. Thus, understanding how these factors control SOC concentration can help to design more sustainable ... -
Bot-graphy: An original technique for plant anatomy study based o metallography
(Cambridge University Press, 2021-07-30)Plant anatomists are recurrently looking for safer and faster methods to improve the observations of plants tissues, searching for images with better resolution. Nevertheless, some plant materials are difficult to handle ... -
Calidad de la materia orgánica y disponibilidad de macro y micronutrientes por la inclusión de trigo como cultivo de cobertura
(2016-06)Los cultivos de cobertura aparecen como una opción que permite mejorar el balance de nutrientes y carbono en el suelo (C). El objetivo del presente trabajo fue determinar el efecto de la incorporación del trigo como cultivo ... -
Catabolic response and phospholipid fatty acid profiles as microbial tools to assess soil functioning
(2016-12)Microbial properties may help to provide an integrated view of changes in soil functioning associated with soil management or soil status. The fatty acid profiles of membrane phospholipids (PLFA) can give the composition ... -
Changes in soil phosphorus in different forest residue management
(INIA Uruguay y Facultad de Agronomía, Universidad de la República, 2012)We analyze the short term effect of the harvest residues management on the Phosphorus (P) fractions of the soil. Four trials were installed in Northeast Argentina on Vertisols (S1), Mollisols (S2) and Entisols (S3 and S4). ... -
