Assessment of different methods for shadow detection in high-resolution optical imagery and evaluation of shadow impact on calculation of NDVI, and evapotranspiration
(Springer Verlag, 2018-12-03)
Significant efforts have been made recently in the application of high-resolution remote sensing imagery (i.e., sub-meter) captured by unmanned aerial vehicles (UAVs) for precision agricultural applications ...
Water primrose invasion changes successional pathways in an estuarine ecosystem
(Ecological Society of America, 2018-09-17)
Invasive species fundamentally change the bio-physical and ecological characteristics of the
ecosystems they invade. Rapidly expanding invasive species may facilitate the spread of other invasive ...
On the accuracy of factory-calibrated low-cost soil water content sensors
(MDPI, 2019-07-13)
Soil water content (SWC) monitoring is often used to optimize agricultural irrigation.
Commonly, capacitance sensors are used for this task. However, the factory calibrations have been
often criticized ...
Looking behind occlusions: A study on amodal segmentation for robust on-tree apple fruit size estimation
(Elsevier, 2023-04-21)
The detection and sizing of fruits with computer vision methods is of interest because it provides relevant information to improve the management of orchard farming. However, the presence of partially ...
A proposal of nitrogen balance in a very high density olive orchard
(El Oued University, 2016-05-01)
The nitrogen (N) balance was estimated in a very high density olive orchard in north- east of Spain, in order to calculate the inputs and outputs of N related to tree response and soil nitrogen availability. ...
Using forced regrowth to manipulate Chardonnay grapevine (Vitis vinifera L.) development to evaluate phenological stage responses to temperature
(Elsevier, 2019-12-06)
Time and environmental conditions, such as temperature and photoperiod, are the main drivers governing grapevine development over the growing season. The most obvious growth periods in grapevines are ...
Post-Harvest Regulated Deficit Irrigation in Chardonnay Did Not Reduce Yield but at Long-Term, It Could Affect Berry Composition
(MDPI, 2019-06-20)
Future increases in temperatures are expected to advance grapevine phenology and
shift ripening to warmer months, leaving a longer post-harvest period with warmer temperatures.
Accumulation of ...
Effect of N dose, fertilisation duration and application of a nitrification inhibitor on GHG emissions from a peach orchard
(Elsevier, 2019-08-23)
Despite only occupying 5% of the worldwide arable area, fruit tree crops are of vital economic importance in many regions. Intensive cropping practices can lead to greenhouse gas (GHG) emissions. In ...
The grape remote sensing atmospheric profile and evapotranspiration experiment
(American Meteorological Society, 2018-10-09)
Particularly in light of California’s recent multiyear drought, there is a critical need for accurate and timely evapotranspiration (ET) and crop stress information to ensure long-term sustainability ...
Accounting for Almond Crop Water Use under Different Irrigation Regimes with a Two-Source Energy Balance Model and Copernicus-Based Inputs
(MDPI, 2022-04-27)
Accounting for water use in agricultural fields is of vital importance for the future prospects for enhancing water use efficiency. Remote sensing techniques, based on modelling surface energy fluxes, ...
