LIDAR as an alternative to passive collectors to measure pesticide spray drift
(Elsevier, 2014)Pesticide spray drift entails a series of risks and costs in terms of human, animal and environmental well-being. A proper understanding of this phenomenon is essential to minimise these risks. However, most conventional ... -
LiDAR simulation in modelled orchards to optimise the use of terrestrial laser scanners and derived vegetative measures
(Elsevier, 2013)Light detection and ranging (LiDAR) technology is beginning to have an impact on agriculture. Canopy volume and/or fruit tree leaf area can be estimated using terrestrial laser sensors based on this technology. However, ... -
Lidar: towards a new methodology for field measurement of spray drift
(Association of Applied Biologists, 2016)Lidar technology is becoming a promising alternative for spray drift measurement to the labour and time-expensive methodologies based on the ISO 22866 standard. This paper presents last advancements in an eye-safe lidar ... -
Linking multiple-level tree traits with biomass accumulation in native tree species used for reforestation in Panama
(Springer Nature, 2007-12-12)To improve establishment yield and carbon accumulation during reforestation, analyses of species adaptations to local environments are needed. Here we measured, at the individual scale, links between biomass accumulation ... -
Lo que los sensores nos dicen sobre las condiciones ambientales de los cultivos
(New Ag International SARL, 2017-10-01)Nuestros bisabuelos y sus antepasados no utilizaban sensores, pero conocían perfectamente sus campos. Esto porque literalmente tenían los pies en la tierra. Ellos tenían que caminar por todos sus terrenos cuando sembraban, ... -
Long-term analysis of soil water conservation and crop yield under different tillage systems in Mediterranean rainfed conditions
(Elsevier, 2016)This study focuses on the quantification of soil water storage and crop yield under different tillage systems in dryland semiarid Mediterranean conditions. Three long-term tillage experiments based on cereal production ... -
Long-term no-till as a means to maintain soil surface structure in an agroecosystem transformed into irrigation
(Elsevier, 2017)The aim of this study was to determine the most appropriate soil management to reduce the structural degradation of soils susceptible to crusting in Mediterranean areas recently transformed into irrigation. A long-term ... -
Long-term yield and water use efficiency under various tillage systems in Mediterranean rainfed conditions
(Wiley, 2007)Conservation tillage (CT) can be beneficial for soil, water and soil organic matter conservation in Mediterranean areas that are prone to soil erosion and where water availability for crops is the main factor for ... -
Los tratamientos fitosanitarios: un paso más hacia la calidad total
(Eumedia, 1994)En un momento en que la agricultura europea ve con incertidumbre los cambios que se avecinan e intenta alianzar políticas intervencionistas que se aseguren la supervivencia del sector, cabe preguntarse si es posible la ... -
Managing stand density to enhance the adaptability of Scots pine stands to climate change: a modelling approach
(Elsevier, 2017)In the Mediterranean region most climatic forecasts predict longer and more intense drought periods that can affect tree growth and mortality over broad geographic regions. One of the silvicultural treatments that has ... -
Mapping vineyard leaf area using mobile terrestrial laser scanners: should rows be scanned on-the-go or discontinuosly sampled?
(Molecular Diversity Preservation International, 2016-01-19)The leaf area index (LAI) is defined as the one-side leaf area per unit ground area, and is probably the most widely used index to characterize grapevine vigor. However, LAI varies spatially within vineyard plots. Mapping ... -
Maquinaria para la explotación forestal
(Eumedia, 1999)La mecanización de los aprovechamientos forestales madereros utiliza una maquinaria concebida especificamente para el trabajo de explotación forestal. Sin embargo, la escasa rentabilidad económica de nuestros bosques ha ... -
Measurement errors in the use of smartphones as lowcost forestry hypsometers
(Suomen Metsätieteellinen Seurary (Finnish Society of Forest Science)Finnish Forest Research Institute, 2014)Various applications currently available for Android allow the estimation of tree heights by using the 3D accelerometer on smartphones. Some make the estimation using the image on the screen, while in others, by pointing ... -
Measurement of spray drift with a specifically designed lidar system
(MDPI, 2016)Field measurements of spray drift are usually carried out by passive collectors and tracers. However, these methods are labour- and time-intensive and only provide point- and time-integrated measurements. Unlike these ... -
Mechanical properties of wood from Pinus sylvestris L. treated with Light Organic Solvent Preservative and with waterbone Copper Azole
(INIA, 2013)Aim of study: To determine the effect on wood from Pinus sylvestris of treatment with preservatives on mechanical properties and to establish the relation between the penetration and compression strenght. Area of study: ... -
Mediterranean forest dynamics and forest bird distribution changes in the late 20th century
(Wiley, 2009)Processes derived from global change such as land-use changes, climate warming or modifications in the perturbation regime may have opposite effects on forest extent and structure with still unknown consequences on forest ... -
Metodología de evaluación del riesgo de incendios forestales y priorización de tratamientos multifuncionales en paisajes mediterráneos
(Universidad de La Rioja, 2019)En las regiones mediterráneas, el efecto combinado del éxodo rural, la falta de gestión forestal y las políticas de supresión de incendios han contribuido notablemente en el aumento de la carga y continuidad de los ... -
Métodos para la determinación del coeficiente de resistencia al flujo en cauces de rugosidad heterogénea
(Colegios y Asociaciones de Ingenieros de Montes e Ingenieros Técnicos Forestales, 2002)Al abordar problemas hidráulicos en cauces en los que la rugosidad varía a lo largo del perímetro, es usual el empleo de un único coeficiente de rugosidad de efectos hidráulicos equivalentes. Desde finales del primer tercio ... -
Mixing of Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.) enhances structural heterogeneity, and the effect increases with water availability
(Elsevier, 2016-04-27)The mixing of tree species with complementary ecological traits may modify forest functioning regarding productivity, stability, or resilience against disturbances. This may be achieved by a higher heterogeneity in stand ... -
