Soil quality impacts of current South American agricultural practices
(Society for Urban Ecology, 2015)Increasing global demand for oil seeds and cereals during the past 50 years has caused an expansion in the cultivated areas and resulted in major soil management and crop production changes throughout Bolivia, Paraguay, ... -
Banco de semillas del suelo en un área de bosques nativos sujeta a cambio en el uso de la tierra (Entre Ríos, Argentina) = Soil seed bank in an area of native forests associated with change in land use (Entre Rios, Argentina)
(Universidad Nacional del Litoral. Facultad de Ciencias Veterinarias, 2016)El objetivo es analizar el banco de semillas del suelo (BSS) en un área de bosques nativos sujeta a cambio de uso de la tierra, y evaluar su rol en la regeneración de estos ecosistemas. Se evaluaron cuatro tratamientos: ... -
Increased cropping intensity improves crop residue inputs to the soil and aggregate-associated soil organic carbon stocks
(Elsevier, 2017-01)Many South American agroecosystems are based mainly on soybean [Glycine max (L.) Merr.] as a sole crop in the year, which has increased concerns regarding soil conservation and ecosystems sustainability. The increase in ... -
Vertical distribution of root biomass and soil carbon stocks in forage cropping systems
(Springer, 2018-02)Background and aims: Forage cropping systems may differentially affect the vertical distribution of roots and soil organic C stock (C-OM). In annual crops sequences (ACS) and perennial pastures (PP), we assessed the ... -
Development and evaluation of an automatic software for management zone delineation
(2018-06)The lack of availability of user-friendly and automatic software for management zone delineation is limiting the adoption of site-specific management practices. Several procedures for management zone delineation have been ... -
Modelling stover and grain yields, and subsurface artificial drainagefrom long-term corn rotations using APSIM
(2018)The Agricultural Production Systems Simulator (APSIM) is a key tool to identify agricultural managementpractices seeking to simultaneously optimize agronomic productivity and input use efficiencies. The aimsof this study ... -
Modelling inter-annual variation in dry matter yield and precipitation use efficiency of perennial pastures and annual forage crops sequences
(2018)In livestock systems of the Argentinean Pampas, its forage production stability relies on the integration of two landcovers, annual forage crop sequences and perennial pastures. Despite the key role that these forage ... -
Limitantes nutricionales y variabilidad espacio-temporal del rendimiento en colza
(2018-04)La información agronómica desarrollada para el cultivo de colza es aún escasa en Argentina. Analizar el efecto de las limitantes nutricionales y de propiedades físicas sobre la variación espacial del rendimiento de colza ... -
Critical bulk density for a Mollisol and a Vertisol using least limiting water range: effect on early wheat growth
(2013-01)The least limiting water range (LLWR) integrates crop growth-limiting values based on easily measurable parameters such as soil water content and bulk density (BD) and has been validated as a valuable soil physical quality ... -
Land use intensity and cropping sequence effects on aggregate stability and C storage in a Vertisol and a Mollisol
(2013)The relevant change in land use duemainly to the rapid expansion of soybean cropping towards areas traditionally occupied for livestock purposes or with native grasslands of South America may have negative consequences on ... -
Determinación de la concentración de glifosato en agua mediante la técnica de inmunoabsorción ligada a enzimas (ELISA)
(2016)Los herbicidas constituyen fuentes potenciales de contaminación, siendo el agua uno de los componentes del ambiente más vulnerables. El glifosato (N-fosfonometil glicina) es el herbicida más utilizado a escala mundial. ... -
Glyphosate loss by runoff and its relationship with phosphorus fertilization
(2015-02-23)The aim of this study was to evaluate the relationship between glyphosate and phosphate fertilizer application and their contribution to surface water runoff contamination. The study was performed in Aquic Argiudoll soil ... -
Platy structure development under no-tillage in the northern humid Pampas of Argentina and its impact on runoff
(2017)The no-tillage system (NT) is widespread in the silty soils of the Argentine Humid Pampas. The aims of this study were i) to characterize the evolution of the structure of the A horizon in the northern Humid Pampas due to ... -
A contribution to understanding the origin of platy structure in silty soils under no tillage
(2016)In silty soils under no tillage (NT), platy (P) soil structure is widespread and constrains water infiltration. Our objectives were (i) to evaluate how traffic and the presence of crop residues influence P structure ...
