Avances en el desarrollo de un sistema de Monitoreo y Control de un Módulo de Producción de Cultivos Hidropónicos para regiones de latitudes elevadas.
(SADIO, 2020-10-26)La agricultura familiar es la forma de producción de alimentos predominante a nivel mundial. En latitudes elevadas, como las de Patagonia Austral, las técnicas de hidroponía compensan factores limitantes como la baja ... -
El cambio climático en los bosques
(REDFOR.ar - ArgentinaForestal - CONICET, 2021-12)El cambio climático es un factor de gran incidencia sobre el desarrollo normal de los diferentes ecosistemas debido al aumento de la temperatura y los cambios sustanciales en los patrones de precipitación, que hacen necesario ... -
Contrasting CO2 and water vapour fluxes in dry forest and pasture sites of central Argentina
(Wiley, 2020-08)The dry forests of South America are a key player of the global carbon cycle and the regional water cycle, but they are being intensively deforested. We used eddy covariance measurements to compare the temporal patterns ... -
Dinámica de las emisiones de N2O, CH4 y CO2 en mallines de Patagonia Norte
(Asociación Argentina de la Ciencia del Suelo, 2020-10-13)Actualmente crece el interés por conocer la contribución que los ecosistemas naturales y los manejados hacen al cambio climático. Las actividades humanas están modificando los ecosistemas dramáticamente y hoy, cerca del ... -
Efecto de la quema prescripta de un pastizal sobre el balance de CO2
(Facultad de Ciencias Agrarias, Universidad Nacional del Nordeste, 2008)El objetivo fue evaluar el efecto de la quema prescripta de un pastizal con predominio de ramíneas sobre la emisión y captura de CO2. El sitio no recibió quema por 25 años. Los tratamientos fueron: T1 = sin quema; T2 = ... -
Effects of elevated CO2 on the water hyacinth-biocontrol agent Megamelus scutellaris (Hemiptera: Delphacidae) and its yeast-like symbiotes
(Elsevier, 2024-01)Water hyacinth, Pontederia crassipes, is a highly invasive plant native to South America and one of the most invasive aquatic plants in the world. For its control, the planthopper Megamelus scutellaris Berg (Hemiptera: ... -
Estrategias para modular los efectos de 1-MCP en peras Packham’s Triumph: aplicación simultánea con etileno con CO2 y tratamientos con calor
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-04)Se realizaron dos experimentos con el objetivo de evaluar la efectividad de diferentes estrategias para recuperar la capacidad de maduración de peras Packham’s Triumph tratadas con 1-metilciclopropeno (1-MCP). Los resultados ... -
Evaluation of storage of sunflower pellets in silo bags
(University of Manitoba, Canadá, 2021-08)Silo bags are a temporary and potentially hermetic storage system widely used for grains, oil seeds, legumes and other products. Oil extraction of sunflower seeds through the extrusion expelling process generates a high ... -
Greenhouse Gas Emissions from Green-Harvested Sugarcane With and Without Post-harvest Burning in Tucumán, Argentina
(2014-06)Concentrations of greenhouse gases (GHG) in the atmosphere are increasing due to anthropogenic actions, and agriculture is one of the most important contributors. This study quantified GHG emissions from green-cane harvested ... -
Huella de Carbono de la cadena de maní de Argentina
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2016-12-14)El objetivo general de este caso de estudio es realizar la Huella de Carbono de la producción, procesamiento y transporte del maní en Córdoba, Argentina, para evaluar la contribución de las emisiones de CO2 equivalente en ... -
Isotopic evidence for oligotrophication of terrestrial ecosystems
(Springer Nature, 2018)Human societies depend on an Earth system that operates within a constrained range of nutrient availability, yet the recent trajectory of terrestrial nitrogen (N) availability is uncertain. Examining patterns of foliar N ... -
Leaf wettability, anatomy and ultra-structure of Nothofagus antarctica and N. betuloides grown under a CO2 enriched atmosphere
(Elsevier, 2023-01)Increasing CO2 air concentration may affect wettability, anatomy and ultra-structure of leaves of Patagonian forest species, evergreen and deciduous plants potentially responding differently to such CO2 increases. In this ... -
Predicting soybean losses using carbon dioxide monitoring during storage in silo bags
(Elsevier, 2019-06)The rapid increase of the overall grain production of Argentina resulted with a storage capacity deficit in permanent structures of 40–50 million tons, and this context favored the rapid adoption of the silo bag technology. ... -
REDD+ en Latinoamérica: el caso de Perú
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2013)La cuestión de cómo los países en vías de desarrollo como el Perú pueden participar efectivamente en el marco REDD+ (reducción de emisiones de la deforestación y degradación de bosques) de las Naciones Unidas ha sido el ... -
Reply to: Data do not support large-scale oligotrophication of terrestrial ecosystems.
(Springer Nature, 2019-07-22)Hiltbrunner et al. apply a reductionist approach to argue that the evidence for widespread terrestrial oligotrophication2 should be replaced with a two-factor explanation (growth dilution and depositional signatures) that ... -
Respiration rates and microbiological development in yellow-dent maize seeds stored between 12% and 14% moisture content
(Elsevier, 2023-12)Understanding microbial development under the typical storage conditions of maize seeds is crucial for maintaining seed quality and ensuring successful crop establishment. In this study, the respiration and microbial growth ... -
Should tree invasions be used in treeless ecosystems to mitigate climate change?
(The Ecological Society of America, 2021)Intentionally allowing or promoting invasion by non-native trees into areas characterized by treeless vegetation could contribute to climate-change mitigation by increasing carbon (C) sequestration. In some areas of the ... -
Soil carbon dioxide and nitrous oxide emissions during the growing season from temperate maize‐soybean intercrops
(Wiley, 2012-06)The Argentine Pampa is one of the major global regions for the production of maize (Zea mays L.) and soybean (Glycine max L. [Merr.]), but intense management practices have led to soil degradation and amplified greenhouse‐gas ... -
