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 ... -
Dinámica y utilización del nitrógeno en el cultivo de cerezo dulce, Prunus avium L.
(Facultad de Agronomía, Universidad de Buenos Aires, 2010)No existen resultados concluyentes en cuanto al efecto del N en el rendimiento del cerezo, las características del fruto, la acumulación de reservas, o el riesgo de lixiviación de nitratos. Por ese motivo, se utiliza ... -
Dissolved organic carbon in water f luxes of Eucalyptus grandis plantations in northeastern Entre Ríos Province, Argentina = Carbono orgánico disuelto en flujos hídricos de plantaciones de Eucalyptus grandis del noreste, provincia de Entre Ríos, Argentina
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2014)Water fluxes in tree plantations and other ecosystems carry dissolved organic carbon (DOC) provided by atmospheric inputs, autotrophic and heterotrophic metabolisms and from the lysis of dead material. These ... -
Distintas especies de gramíneas con potencial uso como cultivos de cobertura. Campaña agrícola 2020
(Estación Experimental Agropecuaria General Villegas, INTA, 2021)Frente a cambios importantes en los sistemas actuales, existe una creciente demanda de información local acerca del comportamiento fenológico y la dinámica de producción de materia seca (MS) de nuevas especies y variedades ... -
Especies herbáceas nativas : aportes para su cultivo como coberturas vegetales en viñedos bajo riego en Mendoza : estudios de intercambio gaseoso, eficiencia hídrica y potencial alelopático de lixiviados
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2013)Los cultivos de cobertura son utilizados dentro del manejo de suelo en viñedos como una herramienta ambientalmente sostenible con diversos objetivos. Mientras que las coberturas verdes contribuyen al secuestro y almacenamiento ... -
Fertilización nitrogenada en un entisol: lixiviación de nitratos y producción del cultivo de naranja
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2022)En Entre Ríos, en la franja costera al Río Uruguay se encuentra aproximadamente un 26 % del total de la superficie plantada con cítricos en Argentina, principalmente sobre suelos arenosos de alta permeabilidad propensos a ... -
Fertilizer vs. organic matter contributions to nitrogen leaching in cropping systems of the Pampas: 15N application in field lysimeters
(Springer, 2006-11-07)Nitrogen (N) export from soils to streams and groundwater under the intensifying cropping schemes of the Pampas is modest compared to intensively cultivated basins of Europe and North America; however, a slowNenrichment ... -
Introduction of cover crops in a maize–soybean rotation of the Humid Pampas: Effect on nitrogen and water dynamics
(Elsevier, 2012-03)The agricultural system of the Humid Pampas consists of continuous cropping of soybean and maize under no tillage. This system may loose nitrogen (N) through leaching during the early and final stages of summer crops and ... -
Long-term vinasse application enhanced the initial dissipation of atrazine and ametryn in a sugarcane field in Tucumán, Argentina
(Wiley, 2023-12)The production of sugarcane bioethanol generates large volumes of vinasse, an effluent whose final disposal can produce an environmental impact that is of concern. The long-term disposal of vinasse in sugarcane fields could ... -
Metsulfuron-methyl and glyphosate transport in a mollisol soil in the Pampean region of Argentina
(Soil Science Society of Pakistan, 2021-12-04)The agricultural activity poses the potential risk of contaminating groundwater resources because of the leaching capacity of the agrochemicals used. Glyphosate and metsulfuron-methyl are two herbicides widely used in the ... -
Nitrate Leaching in an Argiudoll Cultivated with Sugarcane
(2014-09)The aim of the study was to quantify nitrate leaching from an Aquic Argiudoll cultivated with sugarcane in Tucumán, Argentina. Two field trials were conducted during the 2010/2011 and 2011/2012 seasons with the variety LCP ... -
