Simultaneous fruit detection and size estimation using multitask deep neural networks
(Elsevier, 2023-08-06)
The measurement of fruit size is of great interest to estimate the yield and predict the harvest resources in advance. This work proposes a novel technique for in-field apple detection and measurement ...
Parameterization of Soil Hydraulic Parameters for HYDRUS-3D Simulation of Soil Water Dynamics in a Drip-Irrigated Orchard
(MDPI, 2020-06-28)
Although surface drip irrigation allows an efficient use of water in agriculture, the heterogeneous distribution of soil water complicates its optimal usage. Mathematical models can be used to simulate ...
Using Unmanned Aerial Vehicle and Ground-Based RGB Indices to Assess Agronomic Performance of Wheat Landraces and Cultivars in a Mediterranean-Type Environment
(MDPI, 2021-03-20)
The adaptability and stability of new bread wheat cultivars that can be successfully grown in rainfed conditions are of paramount importance. Plant improvement can be boosted using effective high-throughput ...
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 ...
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 ...
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 ...
