Sistema de información de suelos del INTA: Presente y futuro
(Asociación Argentina de la Ciencia del Suelo, 2018-05-15)Durante más de 30 años, a partir de 1964, en Argentina se relevó casi la totalidad del territorio con la finalidad de elaborar mapas de suelos. En ese lapso de tiempo, fue necesaria la descripción y muestreo de más de ... -
Sistema de información para la evaluación de la calidad de suelos de textura fina bajo agricultura en siembra directa en Chaco subhúmedo, En áreas sujetas a cambios en el uso del suelo.
(2018)Con el objetivo de automatizar la evaluación de la calidad de los suelos, se generó un sistema de información (software) simple y amigable. Este sistema permite ingresar los valores de los indicadores medidos en el campo ... -
Sistemas de evaluación de tierras y elaboración de modelos de aptitud de uso agrícola, para distintos escenarios climáticos, en un sector de la subregión pampa arenosa (Provincia de Buenos Aires, Argentina)
(Facultad de Agronomía, Universidad de Buenos Aires, 2011-12)La Pampa Arenosa ha sido escenario de cambios en el uso del territorio que respondieron principalmente al aumento de las precipitaciones a partir de la década del 70. La evaluación de las tierras es una etapa crítica en ... -
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 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 ... -
Status and challenges of black soils
(FAO, 2022-11-05)Although black soils account for only 8.2 percent of the Global Land Area (FAO, 2022a), they are of paramount importance for food security, as highlighted by the UN Sustainable Development Goal 2 (i.e to end hunger, achieve ... -
