Small mammal responses to farming practices in central Argentinian agroecosystems: the use of hierarchical occupancy models
(Ecological Society of Australia, 2018-08)Organic farming is more environmentally friendly than conventional agriculture, promoting greater levels of habitat heterogeneity. Field borders could be more suitable for biodiversity in agricultural anthromes. Small ... -
Soil compaction alleviation by deep non - inversion tillage and crop yield responses in no tilled soils of the Pampas Region of Argentina. A meta - analysis
(Elsevier, 2021-05-03)No till is considered part of the good management practices recommended in conservation agriculture. Regardless of the benefits of this practice, shallow compaction or soil hardening by farm machinery traffic can lead to ... -
Soil compaction response to wheel traffic in the Rolling Pampas region of Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2021-07-07)The present work shows the effects of the different agricultural wheels traffic on the physical properties of a typical Argiudol soil worked under a no-tillage cropping system. Soil compaction produced by traffic was ... -
Soil moisture evaluation over the Argentine Pampas using models satellite estimations and in - situ measurements
(Elsevier, 2020-08-05)Study region: The Pampas region is located in the central-east part of Argentina, and is one of the most productive agricultural regions of the world under rainfed conditions. Study focus: This study aims at examining how ... -
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 ... -
Soil organic carbon, macro- and micronutrient changes in soil fractions with different lability in response to crop intensification
(Elsevier, 2018)Soils under no tillage have experienced unfavorable changes, mainly due to current agricultural practices that consist in monocultures that leave little residue cover. The inclusion of grass as cover crops during the winter ... -
Soil properties evaluation in horticultural farms of Florencio Varela, Buenos Aires, Argentina
(Springer, 2018-06)The south of the green belt of Buenos Aires is one of the most important producers of fresh vegetables in the province. Only few of the horticultural farmers receive professional agronomic advice. For this reason, an excess ... -
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 stabilisation by water repellency under no-till management for soils with contrasting mineralogy and carbon quality
(Elsevier, 2019-08-23)No-till soil management is common around the globe, but the impacts on soil structural quality varies depending on cropping practice and inherent soil properties. This study explored water repellency as a driver of soil ... -
Soil structure and glyphosate fate under no-till management in the Pampa region. I. Soil structural anisotropy and hydro-physical behavior
(Elsevier, 2022-05-03)Several studies have reported a frequent occurrence of platy structures in soils under no tillage (NT), mostly in silty ones. The objective of this study was to evaluate the morphological features and the pore architecture ... -
Soil structure and glyphosate fate under no-till manangement in the pampa region. II. Glyphosate and AMPA persistence and spatial distribution in the long-term. A conceptual model
(Elsevier, 2022-07-14)Glyphosate and AMPA were measured in a no-tilled (NT) soil and in the runoff resulting from the rain simulation carried out after 270 days of the application of the herbicide. Glyphosate concentration was in low values in ... -
Soils of the Chaco Region
(Springer, 2019)The Argentinian Chaco region belongs to an extensive ecoregion called “Great Chaco”, characterized by ample plains of fluvial aggradation and linked to the formation of large alluvial fans. The climate is semi-arid to ... -
Sorpresa Rosa INTA: variedad de lapacho para uso ornamental en maceta
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2017-12)El Instituto de Floricultura de CNIA-INTA (Argentina) desarrolló la primera variedad de Handroanthus heptaphyllus (ex Tabebuia heptaphylla) “Sorpresa Rosa INTA”, apta para uso ornamental en maceta. -
Soybean frogeye leaf spot [Cercospora sojina] : first weather-based prediction models developed from weather station and satellite data
(2015-06-30)In Argentina, soybean frogeye leaf spot occurs sporadically. However, particularly in the Pampas Region, the incidence and severity of this fungal disease have significantly increased in the last years. In the present ... -
Spatial pattern of Pindó Palm (Syagrus romanzoffiana) recruitment in Argentinian atlantic forest: the importance of tapir and effects of defaunation
(Wiley; Association of Tropical Biology and Conservation, 2014-11)Hunting pressure, fragmentation and deforestation have caused global declines in animal abundance, and the consequences for plant communities are poorly understood. Many large‐seeded plants, for instance, depend on large ... -
Spatially variable hidrologic impact and biomass production tradeoffs associated with Eucaliptus ( E. Grandis) cultivation for biofuel production in Entre Ríos, Argentina
(Wiley, 2021-01-11)Climate change and energy security promote using renewable sources of energy such as biofuels. High woody biomass production achieved from short-rotation intensive plantations is a strategy that is increasing in many parts ... -
SSRs, SNPs and DArTs comparison on estimation of relatedness and genetic parameters’ precision from a small half-sib sample population of eucalyptus grandis
(2016)Simple sequence repeats (SSR) are the most widely used molecular markers for relatedness inference due to their multi-allelic nature and high informativeness. However, there is a growing trend toward using high-throughput ... -
Stability and fragmentation versus demographic expansion: different phylogeographic patterns in closely related sympatric legumes (Senna) from arid and semi-arid zones of mid-latitude South America
