Nitrogen balance in a plant-soil system under different cover crop-soybean cropping in Argentina
(2018-10-10)Cover crops (CC) provide many benefits for the soil and the following crop but their effects on nitrogen (N) release and balance in continuous no-tillage soybean (Glycine max L. Merr.) production are little known. Estimation ... -
Winter cover crops in soybean monoculture: effects on soil organic carbon and its fractions
(2016-08)The current agricultural production systems in the Pampas Region have been significantly simplified by cultivating large land areas under no tillage (NT), where soybean is the predominant crop. These systems with long ... -
Biodiesel production from Jatropha curcas: Integrated process optimization
(Elsevier, 2014-04)Energy obtained from renewable sources has increased its participation in the energy matrix worldwide, and it is expected to maintain this tendency. Both in large and small scales, there have been numerous developments ... -
Evaluación de alternativas de manejo de poscosecha en hortalizas de hoja sobre las pérdidas a nivel minorista
(Universidad Nacional del Litoral. Facultad de Ciencias Veterinarias, 2014)Las hortalizas de hoja presentan pérdidas elevadas desde la producción primaria hasta el consumidor. El objetivo fue evaluar las pérdidas poscosecha en acelga, cebolla de verdeo, puerro, rúcula, radicheta y espinaca. Se ... -
Efecto de la cobertura de suelo con acolchados plásticos sobre el comportamiento del cultivo de alcaucil (Cynara cardunculus var. scolymus L.) = Effect of soil coverage with plastic on globe artichoke crop behavior (Cynara cardunculus var. scolymus L.)
(Universidad Nacional del Litoral. Facultad de Ciencias Veterinarias, 2017)Se evaluó el efecto de los polietilenos negros y bicapa sobre el comportamiento del cultivo de alcaucil en la zona de Rosario. Se utilizó el híbrido Madrigal y se evaluaron las variables Número de capítulos por planta, ... -
Environmentally sound resource valuation for a more sustainable international trade : case of argentine maize
(2018)This study analyzed costs and benefits for Argentina when trading maize grain. Assigning an appropriate value to traded resources involves a comprehensive assessment of all kinds of sources driving the process, in order ... -
Utilización de cultivos de cobertura en monocultivo de soja: efectos sobre el balance hídrico y orgánico
(2015-12)Los cultivos de cobertura (CC) son una alternativa para mejorar la falta de cobertura y balance de carbono (C) en suelos bajo siembra directa con monocultivo de soja (Glycine max L. Merr.), predominantes en la Región ... -
Modelo ‘‘cuanti-cualitativo’’ de escurrimiento superficial del agua en suelos agrícolas de la región Pampeana Argentina
(2016-12)Desde hace mucho tiempo se está estudiando la modelación de la relación lluvia-escurrimiento y han sido desarrollados una gran cantidad de métodos y modelos para simular la generación de escurrimiento de una lluvia. Uno ... -
Automatic classification of legumes using leaf vein image features
(2014-01)In this paper, a procedure for segmenting and classifying scanned legume leaves based only on the analysis of their veins is proposed (leaf shape, size, texture and color are discarded). Three legume species are studied, ... -
Multiscale recognition of legume varieties based on leaf venation images
(2014-08)In this work we propose an automatic low cost procedure aimed at classifying legume species and varieties based exclusively on the characterization and analysis of the leaf venation network. The identification of leaf ... -
Environmental assessment of maize production alternatives: Traditional, intensive and GMO-based cropping patterns
(2015-10)The evolution of maize production patterns in Argentina is evaluated over the last 25 years to compare costs, benefits, environmental performance and sustainability as well as to identify the main driving sources and ... -
Time to re-think the GMO revolution in agriculture
(2015-03)Seeds of major crop cultivars provide a vital genetic and cultural link from one human generation to the next. Information embodied in seed is essential to continuity of food production, adaptation to changing climate, and ... -
How land allocation and technology innovation affect the sustainability of agriculture in Argentina Pampas: an expanded life cycle analysis
