The experiment is part of the:
Experimental design:
The research will adopt multidisciplinary approaches and methods to support irrigation optimization in the vineyard. The first step of the proposed activities is the identification of the functional homogeneous zones (fHZs) present in the vineyard through an environmental analysis based on the determination of the soil spatial variability, the micro-morphology of the vineyard (LIDAR) and the spatial variability of the crop response at different resolutions (satellite and drone). The second step will be based on the use and test of field sensors (commercial and experimental) to monitor plant and soil water status in the fHZs in order to define the optimal timing and volume of irrigation to achieve the desired field oenological goals while preserving the water resource.
Step 1 : Identification of fHZs
GIS analysis, pedological survey and evaluation of fHZs
Gephisycal survey in support to the pedological survey
Soil P1 - HZ1
Soil P2 - HZ2
Identification of Homogeneous Zones (HZs)
Analysis on UAV Multispectral data of season 2021
NDVI and GNDVI trends
Definition of long plots and installation of monitoring network in the fHZ1 (irrigation trial)
Weather station
TDR probes (6 nodes. - 4 probes at 4 soil depths)
BIORISTOR sensors
Irrigation system (remote controlled)
Through the UAV multispectral data of 2021 it was possible to identify the grapevine lines in which the plants showed a simila behaviour under the same soil type (P1)
