Aligning citizen science and remote sensing phenology observations to characterize climate change impact on vegetation
(IOPSCIENCE, 2022-08-08)
Phenology observations are essential indicators to characterize the local effects of climate change. Citizen participation in the collection of phenological observations is a potential approach to provide ...
The pitfalls of water potential for irrigation scheduling
(Elsevier, 2020-09-21)
The water potential (Ψp), has been widely used as an indicator of plant water status for irrigation management purposes. The simple infrastructure needed for its measurement and its direct relation to ...
Dynamic Management Zones for Irrigation Scheduling
(Elsevier, 2020-05-07)
Irrigation scheduling decision-support tools can improve water use efficiency by matching irrigation recommendations to prevailing soil and crop conditions within a season. Yet, little research is ...
Agronomic, Physiological and Genetic Changes Associated With Evolution, Migration and Modern Breeding in Durum Wheat
(Frontiers Media, 2021-07-08)
A panel of 172 Mediterranean durum wheat landraces and 200 modern cultivars was phenotyped during three years for 21 agronomic and physiological traits and genotyped with 46,161 DArTseq markers. Modern ...
Cork oak woodland land-cover types classification: a comparison between UAV sensed imagery and field survey
(Taylor and Francis, 2020-07-29)
This work assesses the use of aerial imagery for the vegetation cover characterization in cork oak woodlands. The study was conducted in a cork oak woodland in central Portugal during the summer of 2017. ...
Differential irrigation scheduling by an automated algorithm of water balance tuned by capacitance-type soil moisture sensors
(Elsevier Masson, 2019-11-07)
Automated software tools are required to undertake the routine tasks and decision-making involved in scheduling irrigation. A key issue in this topic is how to integrate sensors in the scheduling approach. ...
Evapotranspiration estimates derived using thermal-based satellite remote sensing and data fusion for irrigation management in California vineyards
(Springer Verlag, 2018-10-10)
Irrigation in the Central Valley of California is essential for successful wine grape production. With reductions in water availability in much of California due to drought and competing water-use ...
The Effect of Photoperiod Genes and Flowering Time on Yield and Yield Stability in Durum Wheat
(MDPI, 2020-12-07)
This study analysed the effect of flowering time as influenced by photoperiod sensitivity genes on yield and yield stability in durum wheat. Twenty-three spring genotypes harbouring different allele ...
An automated and improved methodology to retrieve long-time series of evapotranspiration based on remote sensing and reanalysis data
(MDPI, 2022-12-09)
The large-scale quantification of accurate evapotranspiration (ET) time series has substantially been developed in recent decades using automated approaches based on remote sensing data. However, there ...
Evaluating Soil Resistance Formulations in Thermal‐Based Two‐Source Energy Balance (TSEB) Model: Implications for Heterogeneous Semiarid and Arid Regions
(Wiley, 2018-11-26)
Relatively small fluctuations in the surface energy balance and evapotranspiration in semiarid and arid regions can be indicative of significant changes to ecosystem health. Therefore, it is imperative ...
