Ecosystem Services and Economic Assessment of Land Uses in Urban and Periurban Areas
(Springer, 2020-02-07)This work quantified ecosystem services (ES) and the geographic gross product (GGP) at municipal level in the Metropolitan Region of Buenos Aires (MRBA), Argentina. The ES offer and GGP were evaluated for each land use ... -
Inclusion of Lotus tenuis in beef cattle systems in the Argentinian flooding pampa as an enteric methane mitigation strategy
(Taylor and Francis, 2024-04-01)While concerns about greenhouse gas (GHG) emissions and animal welfare persist, livestock farming offers unique ecosystem services. In Argentina, where livestock significantly contributes to GHG emissions, particularly ... -
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 ... -
Roots are the key for soil C restoration: A comparison of land management in the semiarid Argentinean Pampa
(Elsevier, 2024-01-01)The objective of the study was to elucidate the relationship between soil management and carbon (C) stocks, and to identify the factors that intervene in the processes that favor C sequestration. The study was carried out ... -
Agriculturización en la cuenca alta del Río Luján
(Instituto de Investigaciones Geográficas, Universidad Nacional de Luján, 2023-07-27)El presente trabajo centra su análisis en el proceso de agriculturización ocurrido en las últimas décadas en la Pampa Ondulada, entendido de forma sintética como el reemplazo de la actividad ganadera por la actividad ... -
Soil shrinkage curves and micromorphology in contrasting managements.
(Asociación Argentina de la Ciencia del Suelo, 2020-06-01)Compaction processes are generally described using methods that do not distinguish volume changes of diffe rent types and pore sizes. The adjustment of shrinkage curves (ShC) using the XP model allows elucidation of the ... -
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 ... -
Eruption, transport mechanisms and deposition of Paleogene ignimbrites, southwestern North Patagonian Massif, Argentina
(Elsevier, 2023-11-01)The Paleocene-Eocene Catán Lil Ignimbrite (CLI) is one of the few occurrences within the explosive acid volcanism of this age in the extra-Andean region of the North Patagonian Massif. It represents a small-scale explosive ... -
Mapas de suelos afectados por sales en Argentina
(Red Argentina de Salinidad, 2022)Los suelos afectados por sales (SAS) se encuentran en todos los continentes y bajo casi todas las condiciones climáticas. Se trata de un grupo de suelos con muy diversas propiedades y cuyos rasgos en común son: i.- han ... -
How to Improve Soil Anti-adhesion by Studying the Micro Relief of the Cuticle Surface of Digging Beetles: Exploring the Sulcophanaeus batesi Pronotum Using Translucent Replicas
(Oxford University Press, 2023-09-13)For some years, we have been studying the microtopography of soil diggers beetles fromArgentina to find the anti-adhesion pattern to decrease a soil particle adhesion for agricultural machinery components. In 2018, we ... -
The impact of interventions in the global land and agri-food sectors on nature’s contributions to people and the UN sustainable development goal
(Wiley, 2020-09-01)Interlocked challenges of climate change, biodiversity loss, and land degradation require transformative interventions in the land management and food production sectors to reduce carbon emissions, strengthen adaptive ... -
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. ... -
Coexistence of grasses and shrubs in Patagonian steppes. Norm or exception?
(Wiley, 2023-02-08)Community ecology’s central challenge is to define and corroborate theoretical frameworks that predict -at least in general terms- the composition of communities. The predictive power of a theory based on interspecific ... -
