Spatial variability of short-term effect of tillage on soil penetration resistance
(Taylor & Francis, 2019-04)
The effect of tillage on soil properties varies within field due to spatial variability of soils. Mapping changes of soil penetration resistance (PR) would be useful to understand and assess tillage practices to alleviate ...
Spatio-temporal Nitrogen fertilizer response in maize: Field study and modeling approach
(American Society of Agronomy, 2016-09)
Maize (Zea mays L.) yield and its response to nitrogen (N) are affected by the spatial variability of the interaction between weather, management, and soil properties. The objectives of this study were (i) to evaluate the ...
Vibration of non-homogeneous rectangular membranes with arbitrary interfaces
(Academic Press Ltd - Elsevier Science Ltd, 2007-09)
The study deals with the generalized solution of the title problem. The free vibration problem of a rectangular membrane with partial domains each of uniform density and arbitrary interface is tackled. Previous studies by ...
Approximation by the Finite Element Method to the Preferential Chloride Diffusion through Interfacial Transition Zone in Concrete
(Planta Piloto de Ingeniería Química, 2011-07)
Chloride diffusion in concrete is a main aspect of reinforced concrete durability. It defines the time required for reinforcement corrosion in marine structures. Concrete porosity is one of the main concerns involved in ...
Protocol for multivariate homogeneous zone delineation in precision agriculture
(2016)
La gestión uniforme de los campos agrícolas ha sido cada vez más reemplazado con el medio ambiente gestión basada, que se benefició por la identificación de homogénea zonas dentro de los campos de cultivo. Dichas zonas se ...
Delineation of management zones with soil apparent electrical conductivity to improve nutrient management
(Elsevier, 2013-11)
Site-specific management demands the identification of subfield regions with homogeneous characteristics (management zones). However, determining subfield areas is difficult because of complex correlations and the spatial ...
Development of agroclimatic zoning model to delimit the potential growing areas for macaw palm (Acrocomia aculeata)
(Springer, 2017-08)
The growing biodiesel production requires the use of new technologies and alternative feedstocks to maintain the growing demand of this biofuel. The macaw (Acrocomia aculeata) is a palm native to Argentina whose fruits ...
FastMapping: Software to create field maps and identify management zones in precision agriculture
(Elsevier, 2020-08)
Diverse on-farm agronomic data, gathered via precision agriculture (PA), require depuration and joint analysis of multiple georeferenced field characteristics such as crop yields, and soil and topographic aspects. Multivariate ...
A MASH zone revealed: The mafic complex of the Sierra Valle Fértil
(Oxford University Press, 2015-03)
The Sierra Valle Fértil Complex of west-central Argentina represents a section of the Ordovician (~470 Ma) Famatinian arc and exposes a continuous, tilted crustal arc section ranging in depth from ~12 to 32 km (~4-8 kbar ...
The ≥6-km Cuesta de Randolfo mylonite zone in Ordovician Famatinian peraluminous granites, NW Argentina: Strain-localization as a function of protolith composition
(Pergamon-Elsevier Science Ltd, 2021-12)
The Cuesta de Randolfo mylonite zone (CRMZ) in the southern Puna of Argentina comprises ≥6-km of moderately to steeply dipping proto-to ultramylonites developed in peraluminous intrusive rocks of the Famatinian arc. From ...
