Capacity and Intensity Indicators to evaluate the effect of different crop sequences and cover crops on soil physical quality of two different textured soils from Pampas Region
(Elsevier, 2021-11)Soil physical degradation is a current problem in Molisols of the Pampas Region under no-tillage (NT), that has been related to over-simplified agricultural systems with scarce or no rotations and long winter bare fallows. ... -
Contrasting effects of soil type and use of cover crops on nitrogen and phosphorus leaching in agricultural systems of the Argentinean Pampas
(Elsevier, 2024-01)Agricultural systems of the Argentinean Pampas generally use rotations of summer crops under no-tillage and apply fertilization at rates that do not compensate nutrient exports with grain harvest, resulting in negative ... -
Costos ambientales y eficiencia productiva en la producción agraria del partido de Pergamino
(2013)Mediante un modelo de frontera de producción estocástica se analizó el nivel de eficiencia técnica para la producción de soja, maíz y trigo en empresas agropecuarias del partido de Pergamino, Buenos Aires, Argentina. El ... -
Environmental control of malting barley response to nitrogen in the Pampas, Argentina
(2018-04)Twenty five single-year field experiments were established in order to assess the effects of nitrogen fertilization on grain yield, size, and protein concentration, and to explain its response to fertilization with soil, ... -
Grain hordein content and malt quality as affected by foliar nitrogen fertilisation at heading
(Wiley, 2021-05)Nitrogen fertilisation at heading is a practice for increasing grain protein content in malting barley. The objective of this study was to assess the effects of fertilisation on grain protein, the content and composition ... -
Higher than expected N2O emissions from soybean crops in the Pampas Region of Argentina: Estimates from DayCent simulations and field measurements
(Elsevier, 2022-08)In developing countries, agriculture generally represents a large fraction of GHG emissions reported in National Inventories, and emissions are typically estimated using Tier 1 IPCC guidelines. However, field data and ... -
Maize genetic progress in the central Pampas of Argentina: effects of contrasting sowing dates
(Elsevier, 2022-05)Delayed sowing date of maize (Zea mays L.) has become a broadly adopted practice in the Pampas region of Argentina, because late-sown crops frequently experience a more favorable water balance around flowering and a reduction ... -
Modeling economic-environmental decision making for agricultural land use in Argentinean Pampas
(2016-03)This research evaluates the economic and environmental impacts of land allocation to crops and extensive livestock production in the Argentine Pampas using compromise programming. Two economic indicators (gross margin, ... -
Phosphorus and nitrogen fractions during base flow conditions of a Pampean stream and their relationship with land use
(Asociación Argentina de Ecología, 2020-12)During the last decades, population growth and the associated intensification of anthropogenic activities (agriculture, industrialization and urbanization) increased nutrient inputs to Pampean lotic waterbodies. However, ... -
Predicting junglerice (Echinochloa colona L.) emergence as a function of thermal time in the humid pampas of Argentina
(Taylor & Francis, 2020-06)Junglerice (Echinochloa colona) is one of the most important annual weeds affecting crops in Argentina. A predictive seedling emergence model based on thermal time was developed and validated. Monitoring of seedling emergence ... -
Rural landscape simplification and provision of cultural ecosystem services : a case study in the Argentine Pampas
(Universitat Politécnica de Valéncia, 2023-06)In recent decades, the rural landscape of the Argentine Pampas has undergone a process of simplification due to the increased land allocated to crops, replacing pastures and grasslands, with a substantial increase in soybean ... -
Soil porosity characteristics and water movement under zero tillage in silty soils in Argentinian Pampas
(Elsevier, 2006-05)The objective of this study was to identify pore characteristics (quantity, distribution, stability and orientation of pores) that condition water dynamics under continuous zero tillage (ZT) on silty soils of the Argentinian ... -
Sulfur fertilization technology in the Argentine Pampas region : a review
(Facultad de Agronomía, Universidad de Buenos Aires, 2012-05)Sulfur (S) deficiencies in grain crops have become increasingly frequent worldwide, including the Argentine Pampas region, located in South America. The objective of this work is to review recent research literature regarding ...
