Carbon-scaled nitrous oxide emissions better reflect the impacts of land use changes than raw nitrous oxide emissions in the Dry Chaco region
(Elsevier, 2024-10)In the Dry Chaco region, agriculture expansion has caused significant land use change hotspots. However, the post-impact of land use change on nitrous oxide (N2O) emissions and carbon (C) budgets remains unknown. This study ... -
Service crops improve a degraded monoculture system by changing common bean rhizospheric soil microbiota and reducing soil-borne fungal diseases
(Oxford University Press, 2021-02)Intensive agricultural practices have resulted in progressive soil degradation, with consequences on soil ecosystem services. The inclusion of service crops is a promising alternative to support the sustainability of the ... -
Short-term service crops affect the spatial organization of soil aggregates, microbial C–N biomass, and microbial activities in a degraded monoculture system
(Elsevier, 2024-07)Service crops are grown to provide ecosystem services, such as the ability to increase soil organic matter and fertility. Also, they reduce erosion processes, weed control, disease regulation, water purification, soil ... -
Carbon Dioxide and Nitrous Oxide Emissions from a Typical Sugarcane Soil in the Cauca River Valley, Colombia
(Springer, 2024-02)Sugarcane is an important crop for tropical countries and to accurately inventory its greenhouse gas (GHG) emissions baseline measurements are needed. In Colombia, sugarcane is one of the most important crops in terms of ... -
Where did the forest go? Post-deforestation land use dynamics in the Dry Chaco region in Northwestern Argentina
(Elsevier, 2023-06)Land transformation is a major component of global change, directly altering habitat composition and spatial configuration, biodiversity, and ecosystem functioning. Over the last decades, the Dry Chaco region in Northwestern ... -
Effect of two broad-spectrum fungicides on the microbial communities of a soil subjected to different degrees of water erosion
(Elsevier, 2023-10)The impact of both fungicide and water erosion on soil microbial communities has been little studied, and far less in subhumid-dry climates. To help fill this knowledge gap, we evaluated the influence of two broad-spectrum ... -
Adequate supplemental irrigation amount during the critical period for yield in chia prevents reductions in radiation capture, radiation and water use efficiencies, and grain yield
(Springer, 2024-05)Chia is generally grown under rainfed conditions and is often under water deficit conditions during the critical period of flowering and grain filling when yield is determined. The objective of this study was to determine ... -
Corrugated intimal surface of the ovine aorta: when physiology resembles pathology
(Elsevier, 2024-05)The aortic lumen in healthy animals is characterized by a smooth, whitish surface, but sheep have macroscopic corrugation of the intimal surface in the thoracic aorta (TA). Our aim was to determine if this finding was ... -
Estudio de las posibles causas de mermas reproductivas luego del servicio en la cría bovina en el Noroeste Argentino = Study of the possible causes of post mating reproductive losses in beef cattle farming in Northwest Argentine = Estudo das possíveis causas de perdas reprodutivas após serviço na criação bovina no Noroeste Argentino
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Pampa, 2024-02-14)Con el propósito de diagnosticar la presencia de posibles causas de mermas reproductivas se realizaron encuestas y conformaron 4 grupos de vientres bovinos luego de finalizado el servicio en 5 establecimientos salteños de ... -
Characterization and Agronomic Evaluation of Chia Germplasm in La Plata, Buenos Aires, Argentina
(MDPI, 2022-10)Chia (Salvia hispanica L.), an ancestral crop currently revalued for its nutritional properties, is one of the main sources of omega-3 fatty acids. It is a short-day plant and sensitive to frost. The objective of this study ... -
Soil Properties and Bacterial Communities Associated with the Rhizosphere of the Common Bean after Using Brachiaria brizantha as a Service Crop: A 10-Year Field Experiment
(MDPI, 2023-01)Intensive agricultural farming practices, such as monoculture, require long bare fallow periods and the overuse of agrochemicals, which compromise soil health over time. Increasing plant diversity in agroecosystems with ... -
Índices climáticos de precipitación y temperatura de San José de Metán, Salta, Argentina
(Asociación Argentina de Agrometeorología, 2022-08-12)El cambio climático está afectando a los patrones de precipitación, hay probabilidad de que aumenten en las latitudes altas, mientras que en las regiones subtropicales se prevé su disminución. El objetivo del trabajo es ... -
The critical period for grain yield in chia (Salvia hispanica)
(CSIRO, 2021-03-30)Chia (Salvia hispanica L.) grain is rich in omega-3 and omega-6 fatty acids, which are important for human nutrition and prevention of cardiovascular disease, as well as dietary fibre and quality protein. Demand for chia ... -
Integrating critical values of soil drivers for mitigating GHGs: An assessment in a sugarcane cropping system
(Elsevier, 2020-02)Agricultural practices can reduce emissions of greenhouse gases (GHG). The definition of management practices toward mitigating GHG emissions could gain accuracy by integrating critical values of soil variables related to ... -
Fecha de trasplante y requerimientos de nutrientes (N-P-K) en lotes tabacaleros de Salta (Argentina)
(Asociación Argentina Ciencia del Suelo, 2014-11-16)El tabaco se caracteriza por poseer una restringida ventana de oportunidad de captación de los recursos en virtud de su corto ciclo de vida. La disponibilidad, absorción y distribución de nutrientes esenciales, especialmente ... -
Sowing density rather than row spacing influences chia radiation use and yield
(Wiley, 2022-10)Chia (Salvia hispanica L.) production worldwide has been encouraged due to its high essential fatty acid content that is effective for reducing cardiovascular affections. However, few studies have assessed the sowing density ... -
The dialectics of capital: learning from Gran Chaco
