Seguridad alimentaria y ambiental en tratamientos fitosanitarios
(Eumedia, 2002)Mientras el consumo de productos fitosanitorios se mantiene en España, el control químico de los organismos competidores de los cultivos cada vez se realiza con una mayor calidad. La seguridad alimentaria i el cuidado del ... -
Sensitivity of tree volume measurement to trajectory errors from a terrestrial LIDAR scanner
(Elsevier, 2010)The use of terrestrial LIDARs in agriculture enables the measurement of structural parameters of the orchards such as the volume of the trees. The sequence of two-dimensional scans performed with a LIDAR attached to a ... -
Setting the optimal length to be scanned in rows of vines by using mobile terrestrial laser scanners
(Springer Science+Business Media, 2017)Mapping the leaf area index (LAI) by using mobile terrestrial laser scanners (MTLS) is of significance for viticulture. LAI is related to plant vigour and foliar development being an important parameter for many agricultural ... -
Shade tolerance and the functional trait - demography relationship in temperate and boreal forests
(British Ecological Society, 2017)Despite being instrumental in forest ecology, the definition and nature of shade tolerance are complex and not beyond controversy. Moreover, the role it plays in the trait-demography relationship remains unclear. Here, we ... -
Short communication.Wood identification based on their common name and their transversal surface anatomy. Application to the batch from the expedition of Ruiz and Pavon
(Instituto Nacional de Investigación y Tecnologia Agraria y Alimentaria, 2011)Aim of study: To identify species of wood samples based on common names and anatomical analyses of their transversal surfaces (without microscopic preparations). Area of study: Spain and South America Material and methods: ... -
SIMLIDAR – Simulation of LIDAR performance in artificially simulated orchards
(Elsevier, 2012)SIMLIDAR is an application developed in C++ that generates an artificial orchard using a Lindenmayer system. The application simulates the lateral interaction between the artificial orchard and a laser scanner or LIDAR ... -
Sistema semiautomático para riego por superficie
(Reed Business Information, 1998)El sistema es aplicable para riego por tablares, y permite automatizar las acciones de apertura y cierre de una serie de compuertas durante un riego. El sistema está compuesto por una compuerta giratoria que es movida por ... -
Six-year time course of light-use efficiency, carbon gain and growth of beech saplings (Fagus sylvatica) planted under a Scots pine (Pinus sylvestris) shelterwood
(Oxford University Press, 2007-08-01)Two-year-old Fagus sylvatica L. saplings were planted under the cover of a Pinus sylvestris L. stand in the French Massif Central. The stand was differentially thinned to obtain a gradient of transmitted photosynthetically ... -
Software para la mejora del aprendizaje del cálculo estructural en ingeniería y arquitectura.Programa Barras V-2.0, Universitat de Lleida
(CIDUI Congrés Internacional de Docència Universitària i Innovació, 2012)Actualmente, para abordar el cálculo estructural en la Universitat de Lleida existe software de uso profesional. Los dos grandes inconvenientes para aplicarlo como herramienta de docencia son, su alto coste económico y ... -
Soil biochemical properties in a semiarid Mediterranean agroecosystem as affected by long-term tillage and N fertilization
(Elsevier, 2013)Tillage and N fertilization practices contribute to the balance between soil C inputs and outputs. Thus, the impacts of both practices and their interactions on soil organic C (SOC) dynamics must be studied. The main ... -
Soil carbon dioxide flux and organic carbon content: effects of tillage and nitrogen fertilization
(Soil Science Society of America, 2011)Th e response of soil CO2 fl ux to long-term tillage practices (no-tillage, NT; minimum tillage, MT; conventional tillage, CT) and N fertilization level (zero; medium, 60 kg N ha–1; high, 120 kg N ha–1) was studied during ... -
Soil CO2 fluxes following tillage and rainfall events in a semiarid Mediterranean agroecosystem: Effects of tillage systems and nitrogen fertilization
(Elsevier, 2010)The response of soil CO2 flux to tillage operations and rainfall events was studied under semiarid Mediterranean conditions. The study was conducted on a barley monoculture agro-ecosystem during summer/autumn fallow ... -
Soil organic carbon storage in a no-tillage chronosequence under Mediterranean conditions
(Springer, 2014)The duration of soil organic carbon (SOC) sequestration in agricultural soils varies according to soil management, land-use history and soil and climate conditions. Despite several experiments have reported SOC sequestration ... -
Spatial variability in commercial orange groves. Part 1: canopy volume and height
(Springer, 2018-09-22)Characterizing crop spatial variability is crucial for estimating the opportunities for site-specific management practices. In the context of tree crops, ranging sensor technology has been developed to assess tree canopy ... -
Spatial variability in commercial orange groves. Part 2: relating canopy geometry to soil attributes and historical yield
(Springer, 2018-10-16)Site-specific management strategies are usually dependant on the understanding of the underlying cause and effect relationships that occur at the within-field level. The assessment of canopy geometry of tree crops has been ... -
Spatial variability in grape yield and quality influenced by soil and crop nutrition characteristics
(Springer, 2012)Knowledge of spatial variability of soil fertility and plant nutrition is critical for planning and implementing site-specific vineyard management. To better understand the key drivers behind vineyard variability, yield ... -
Spatial variability in orchards after land transformation: consequences for precision agriculture practices
(Elsevier, 2018)The change from traditional to a more mechanized and technical agriculture has involved, in many cases, land transformations. This has supposed alteration of landforms and soils, with significant consequences. The effects ... -
Spatially variable pesticide application in vineyards: Part I, developing a geostatistical approach
(ElsevierAcademic Press, 2020-05-18)A geostatistical methodology is presented to optimise the dosage of plant protection products (PPP) in vineyards with spatial variability. Sprayers are commonly used in viticulture to apply a constant volume rate per unit ... -
Spatio-temporal configurations of human-caused fires in Spain through point patterns
(MDPI, 2016)Human-caused wildfires are often regarded as unpredictable, but usually occur in patterns aggregated over space and time. We analysed the spatio-temporal configuration of 7790 anthropogenic wildfires (2007–2013) in nine ... -
