Landscape structure in urban and periurban areas in the Metropolitan Region of Buenos Aires (MRBA)
(University of Architecture and Urban Planning, Rumania, 2023)Urban and peri urban landscapes, as well as rural landscapes, exhibit diverse spatial patterns related to components or uses diversity (e.g: agricultural lots, forests, urban reserves, city settlements among others). ... -
Soil hydro-physical variables and crop residues determinate runoff soil loss, and glyphosate and AMPA concentration in the aqueous phase under simulated rainfall events
(Wiley, 2024-07-09)Soil structural degradation and water erosion processes were observed even in no-tillage schemes in the Pampas region. Within these conservation systems, agrochemical application per hectare is one of the highest globally. ... -
Topsoil hardening: effects on soybean root architecture and water extraction patterns
(Springer, 2020-09-01)Topsoil hardening is one of the major causes of poor root growth although its effects on subsoil roots are still not well-known. Our aim was to examine the effects of topsoil hardening on the growth and functioning of ... -
Comparación de indicadores de la desertificación en la Región Pampeana y en la frontera de expansión agropecuaria en la República Argentina = Desertification indicators comparison in Pampean Region and agricultural expansion frontier in the Argentine Republic
(Facultad de Agronomía, Universidad Nacional de La Plata, 2023-11-01)El proceso de desertificación se está generalizando en la Argentina. En la Región Pampeana y Extra Pampeana, la generalización del monocultivo de soja y el manejo no sustentable han aumentado el proceso de desertificación. ... -
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
