Towards an Optimized Method of Olive Tree Crown Volume Measurement
(MDPI, 2015)
Accurate crown characterization of large isolated olive trees is vital for adjusting
spray doses in three-dimensional crop agriculture. Among the many methodologies
available, laser sensors have proved to be the most ...
Design of a Soil Cutting Resistance Sensor for Application in Site-Specific Tillage
(MDPI, 2013)
One objective of precision agriculture is to provide accurate information about
soil and crop properties to optimize the management of agricultural inputs to meet
site-specific needs. This paper describes the development ...
Design of a New Sensor for Determination of the Effects of Tractor Field Usage in Southern Spain: Soil Sinkage and Alterations in the Cone Index and Dry Bulk Density
(MDPI, 2012)
Variations in sinkage and cone index are of crucial importance when planning
fieldwork, and for determining the trafficability of farm machinery. Many studies have
highlighted the link between higher values of these ...
Vibration Monitoring of the Mechanical Harvesting of Citrus to Improve Fruit Detachment Efficiency
(MDPI, 2019)
The introduction of a mechanical harvesting process for oranges can contribute to enhancing farm profitability and reducing labour dependency. The objective of this work is to determine the spread of the vibration in citrus ...
Development of a Telemetry and Yield-Mapping System of Olive Harvester
(MDPI, 2015)
Sensors, communication systems and geo-reference units are required to achieve
an optimized management of agricultural inputs with respect to the economic and
environmental aspects of olive groves. In this study, three ...
Olive Crown Porosity Measurement Based on Radiation Transmittance: An Assessment of Pruning Effect
(MDPI, 2016)
Crown porosity influences radiation interception, air movement through the fruit orchard,
spray penetration, and harvesting operation in fruit crops. The aim of the present study was to develop
an accurate and reliable ...
Olive Actual “on Year” Yield Forecast Tool Based on the Tree Canopy Geometry Using UAS Imagery
(MDPI, 2017)
Olive has a notable importance in countries of Mediterranean basin and its profitability
depends on several factors such as actual yield, production cost or product price. Actual “on
year” Yield (AY) is production (kg ...
Assessment of Spray Deposit and Loss in Traditional and Intensive Olive Orchards with Conventional and Crop-Adapted Sprayers
(MDPI, 2022)
Plant protection product (PPP) applications to isolated olive trees are commonly performed with regular air-assisted sprayers, which are not adapted to their particular characteristics. Whilst strong efforts have been ...
The contribution of fruit and leaves to the dynamic response of secondary branches of orange trees
(Elsevier, 2020)
The current commercial technologies for mass harvesting fruit are based on the
application of forced vibration to the tree, which is transmitted to the fruits causing their
detachment. The dynamic behaviour of the plant ...
The vibration behaviour of hedgerow olive trees in response to mechanical harvesting with straddle harvester
(Elsevier, 2019)
Understanding tree behaviour under mechanical harvesting is very important for orchard management and machine design. The objective of this work is to determine the Dynamic response of trees, in a hedgerow arrangement, to ...
