Comparison between standard and drift reducing nozzles for pesticide application in citrus: Part II. Effects on canopy spray distribution, control efficacy of Aonidiella aurantii (Maskell), beneficial parasitoids and pesticide residues on fruit
(Elsevier, 2017)Venturi nozzles are often recommended to reduce drift, which is one of the major pollution sources caused by the application of plant protection products on high growing crops. The coarse droplets produced by this type of ... -
Competition for water between beech seedlings and surrounding vegetation in different light and vegetation composition conditions
(Institut National de la Recherche Agronomique (INRA)EDP Sciences, 2003)To gain a better understanding of beech growth requirements and assess the competition with the surrounding vegetation at two successional stages after agricultural land abandonment, we introduced two-year-old beech seedlings ... -
Comprendiento la geolocalización y navegación y su uso en Agricultura de Precisión
(New Ag International SARL, 2017-04-01)Se dice que el GPS gatilló la Agricultura de Precisión (PA), permitiendo que se generaran los primeros mapas de rendimiento. Esto puede que sea preciso o no, pero lo que es cierto es que los sistemas de geoposicionamiento ... -
Connectivity conservation priorities for individual patches evaluated in the present landscape: how durable and effective are they in the long term?
(Wiley, 2015)One of the most widespread approaches for setting spatially-explicit priorities for connectivity conservation consists in evaluating the effects of the individual removal of each habitat patch (one at a time) from the ... -
Consideraciones acerca de los límites de aplicación del método del número de Curva del Soil Conservation Service
(Colegios y Asociaciones de Ingenieros de Montes e Ingenieros Técnicos Forestales, 2001)En el presente artículo se revisan las limitaciones de aplicación del método del Número de Curva del Soil Conservation Service, modelo conceptual ampliamente difundido para el cálculo de la escorrentía originada por una ... -
Contrasting patterns of tree species mixture effects on wood δ13C along an environmental gradient
(Springer Nature, 2019-09-06)Establishing mixed-species stands is frequently proposed as a strategy to adapt forests to the increasing risk of water scarcity, yet contrasted results have been reported regarding mixing effects on tree drought exposure. ... -
Corrección de cauces torrenciales
(Colegio de Ingenieros Técnicos de Obras Públicas (Madrid), 1997)Las cuencas torrenciales presentan una respuesta hidrológica caracterizada por avenidas súbitas y violentas, que transportan grandes cantidades de material sólido, pudiendo afectar gravemente a las infraestructuras de áreas ... -
Cost reduction in pressurized irrigation networks under a rotation schedule
(Springer Nature, 2020-07-10)Rotation scheduling implies a reduction in pipe flows and, consequently, in network cost. This kind of scheduling is considered rigid, but the recent development of new technologies, such as Supervisory Control And Data ... -
Coupling a water balance model with forest inventory data to predict drought stress: the role of forest structural changes vs. climate changes
(Elsevier, 2015-07-09)Mechanistic water balance models can be used to predict soil moisture dynamics and drought stress in individual forest stands. Predicting current and future levels of plant drought stress is important not only at the local ... -

Cómo obtener y qué hacer con los mapas de colores
(New Ag International SARL, 2018-05-01)Desde nuestro primer artículo, esta sección ha ido siguiendo el ciclo de la Agricultura de Precisión (AP). Hasta ahora, hemos descrito cómo obtener datos georreferenciados mediante observaciones visuales o a través de ... -
Criterios para la selección del tractor frutero
(Eumedia, 1998)La selección del tractor más adecuado para una determinada explotación frutícola requiere considerar dos aspectos fundamentales. En primer lugar, el fruticultor debe valorar la conveniencia económica de la adquisición ... -
Crown bulk density and fuel moisture dynamics in Pinus pinaster stands are neither modified by thinning nor captured by the Forest Fire Weather Index
(Springer Nature, 2017-06-28)Key message. No temporal change was recorded during summer in fuel availability in Pinus pinaster stands, contrary to predictions from the Forest Fire Weather Index. Also, thinning had no mid-term effect on fuel moisture ... -
Data management and decision making: when Precision Agriculture puts us in trouble
(New Ag International SARL, 2018-06-01)The use of sensors in Precision Agriculture together with the trend of increasing spatial and temporal sampling resolutions, lead to the generation of huge amounts of data. The appropriate management of such data sets to ... -
Deciduous tree reconstruction algorithm based on cylinder fitting from mobile terrestrial laser scanned point clouds
(Elsevier, 2014)Vector reconstruction of objects from an unstructured point cloud obtained with a LiDAR-based system (light detection and ranging) is one of the most promising methods to build three dimensional models of orchards. The ... -
Deposición transversal de líquido de las boquillas de doble abanico TTJ60-11004 y TTJ60-11002 en distintas condiciones operacionales
(Sociedade Brasileira da Ciência das Plantas Daninhas, 2009)El objetivo de este trabajo fue el de evaluar la deposición transversal de caldo de las boquillas pulverizadoras de doble abanico TTJ60-11004 y TTJ60-11002 en distintas condiciones operacionales. Se utilizaron 5 muestras ... -
