Adsorption and transport of imazapyr through intact soil columns taken from two soils under two tillage systems
(2015)The objective of this work was to study the sorption and transport of imazapyr (IMZ) in two soils with different physical–chemical properties, subject to long-term conventional tillage (CT) and no-tillage (NT) systems. ... -
Assessing the glyphosate tolerance of Lotus corniculatus and L. tenuis to perform rhizoremediation strategies in the Humid Pampa (Argentina)
(2016)The broad-spectrum herbicide glyphosate (N – phosphonomethylglicine) is the most common pesticide used in the Humid Pampa, the main agricultural region in Argentina. According to agronomical practices and topogeographical ... -
SPR Biosensing MUA/Poly-L-lysine platform for the detection of 2,4-Dinitrophenol as small molecule model system
(2016-10-18)Surface Plasmon Resonance assays are being developed as alternative biodetection methods for a great number of pesticides and toxins.These substances typically have low molecular weight, making it necessary to perform ... -
Vetch-rye biculture is a sustainable alternative for enhanced nitrogen availability and low leaching losses in a no-till cover crop system
(2017-12)The reliance of current farming systems on synthetic fertilizers caused concerns about their sustainability, and alternatives to supply nitrogen through biological processes have to be adapted to practical conditions. The ... -
Soil quality and productivity under zero tillage and grazing on Mollisols in Argentina – A long-term study
(2017-12)The growing global demand for food, fibers and energy has triggered a scientific and political debate on how to attain increasing land productivity without further degrading soils. The objective of this study was to quantify ... -
True bugs (hemiptera: heteroptera) associated with soybean glycine max (L.) merr.) in southern cone
(2017)The area selected for growing soybean (Glycine max (L.) Merr.) in Argentina, has increased in the last few years; reaching 28.6 millions hectars throughout the country, out which, 500.000 belong to La Pampa province. ... -
Dynamics of volcanic ash remobilisation by wind through the Patagonian steppe after the eruption of Cordón Caulle, 2011
(2017)Wind erosion of freshly-deposited volcanic ash causes persistent storms, strongly affecting ecosystems and human activity. Wind erosion of the volcanic ash was measured up to 17 months after the ash deposition, at 7 sites ... -
Mapeo de la agricultura urbana y periurbana en el área metropolitana Santa Rosa-Toay: aproximaciones metodológicas para la lectura territorial
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2017-12)Es abundante la evidencia científica acerca de los beneficios a la sociedad que conlleva la agricultura urbana y periurbana, aunque de manera contradictoria también se evidencian potenciales impactos negativos a la salud ... -
Crop and tillage effect on water productivity of dryland agriculture in Argentina
(2013)Rising demands for food and uncertainties about climate change call for a paradigm shift in water management with a stronger focus on rainfed agriculture. The objective here was to estimate water productivity of different ... -
Estudio de la contribución de nitrógeno por parte de los cultivos de cobertura al cultivo de maíz
(2013-03)El principal objetivo de este trabajo fue determinar los efectos del centeno como CC y del manejo de la fertilización nitrogenada del mismo, sobre la producción de grano y absorción de N de un cultivo posterior de maíz en ... -
Efecto de la quema controlada sobre el banco de semillas de gramíneas en diferentes parches del bosque de calden en la región semiárida central Argentina
(2015)El banco de semillas del suelo es la principal reserva de propágulos con que cuenta una comunidad vegetal para su mantenimiento, regeneración y perpetuación. Las quemas controladas pueden producir cambios en su composición ... -
Cow management modulates gene expression in the mammary gland, a possible epigenetics role
(2015)Epigenetics, the study of the change in gene expression that occurs without alteration in DNA sequences, leads to modifications that can be passed on by mitosis. It has been known for many years that cow management during ... -
Aggregation kinetics of humic acids in the presence of calcium ions
(2013)The aggregation kinetics of a humic acid (HA) sample as a function of Ca2+ concentration at pH 5, 7 and 9 was investigated. UV–VIS spectroscopy was employed to quantify the progress of the aggregation reaction, and ... -
RWEQ wind erosion predictions for variable soil roughness conditions
(2016)The soil surface is a main factor in all wind erosion prediction models including the Revised Wind Erosion Equation (RWEQ). The objetive of this study was to test the erodibility of two typical soils of the semiarid ... -
Direct field method for root biomass quantification in agroecosystems
(2016)The present article describes a field auger sampling method for row-crop root measurements. In agroecosystems where crops are planted in a specific design (row crops), sampling procedures for root biomass quantification ... -
Effect of different cover crops on C and N cycling in sorghum NT systems
(2016)In many no-till (NT) systems, residue input is low and fallow periods excessive, for which reasons soil degradation occurs. Cover crops could improve organic matter, biological activity, and soil structure. In order to ... -
High quality residues from cover crops favor changes in microbial community and enhance C and N sequestration
(2016)The objective of the study was to evaluate the effect of a change in management on the soil microbial community and C sequestration. We conducted a 3-year field study in La Pampa (Argentina) with rotation of sorghum (Sorghum ... -
Supplementation of glycerol or fructose via drinking water to grazing lambs on tissue glycogen level and lipogenesis
(2017)Lambs (n = 18; 40.1 ± 7.4 kg BW) were used to assess supplementation of glycerol or fructose via drinking water on growth, tissue glycogen levels, postmortem glycolysis, and lipogenesis. Lambs were blocked by BW and allocated ... -
