OTIVINYA: Grape harvest ripening and quantity control optimisation
OTIVINYA: Optimización del control de maduración y cantidad de la cosecha de la vid
Contexte
The aim of the project is to use technology to assess the condition of the crop as a whole, considering the vineyard to be a set of plots. Current agricultural plots will be used as the management and study units. Therefore, the tool developed may be very useful for associations that bring together a large number of producers, such as cooperatives, ADV, DO, etc.
To this end, the project is based on determining the usefulness of high-resolution remote sensing using satellite image time series and one-off drone images to determine the vigour of the plants and correlate it to a number of variables to predict the quantity of harvest and its classification in terms of quality. Thus, in addition to capturing data from aerial systems in order to calculate the vegetation index, during the project intense fieldwork was conducted to measure grape yield and quality parameters from the end of veraison (100%) to harvest. The relation between these parameters will enable allows algorithms to be produced that can be used to make predictions on harvest yield and optimal harvest dates in accordance with the grape ripening speed, assuming that one of the variables that affect ripening is the state of vegetation cover (robustness, density, health, etc.). It should also be stated that grapes in the area of El Penedès are cultivated in dry land conditions, which makes the monitoring and forecasting of the grape growth and ripening parameters more complicated.
Objectives
The main objective is to provide the wine sector (especially in dry zones) with tools to control the amount of harvest and ripening of the different plots in order to determine the date of harvest and its quality more accurately, using data from remote sensing systems.
The specific objectives are:
− Correlate the aerial data and validate them against the field variables for each one of the varieties being studied (Xarel·lo and Macabeu).
− Prepare growth curves throughout the grape ripening period in order to make harvest predictions.
− Determine the classification models to attempt to project quality parameters
− Assess the quality of the wine produced
− Assess the economic viability of these actions.
Objectives
El objetivo es proveer al sector vitivinícola de herramientas de control de la cantidad de la cosecha y de la maduración para determinar su calidad y la fecha de vendimia óptima, mediante teledetección.
Los objetivos específicos son:
- Desarrollar la correlación y validación de los datos aéreos con las variables de campo para cada una de las variedades en estudio (Xarel·lo y Macabeo).
- Crear curvas de crecimiento durante la maduración de la uva con el fin de conocer de antemano las previsiones de cosecha.
- Determinar modelos de clasificación para tratar de proyectar parámetros de calidad en las diferentes parcelas.
- Evaluar la calidad enológica de las vinificaciones producidas
- Cálculo de costes
Activities
1. Remote sensing for crop monitoring:
From March 2018 until the end of September 2020, a weekly satellite image of 30 wine plots was taken. A total of 63 experimental blocks were defined within the plots . Later on, a fixed-wing drone flew over the project plots, with the aim of validating satellite information.
2. Field sampling to monitor ripening
3. Quality assessment:
The end goal of the project is to help winery managers who have to make decisions on when to harvest and especially which plots need to be harvested. Thus the goal was set of assessing the quality that each oenologist (from each winery) would give to the combination of the degree, pH and total acidity (TotA) parameters.
4. Data analysis
Activities
1. Teledetección para el seguimiento del cultivo:
Entre marzo de 2018 y septiembre de 2020 se tomó una imagen semanal por satélite de 30 parcelas .Posteriromente, un dron de ala fija sobrevoló las mismas parcelas para validar los datos de los satélites.
- Muestreo a campo para hacer seguimiento de la maduración
- Evaluación de la calidad
El objetivo final del proyecto es poder ayudar a los responsables de cada bodega que tienen que tomar la decisión de cuándo se ha de recoger, y sobre todo que parcelas hay que cosechar. Así se propuso como objetivo evaluar la calidad que cada enólogo (de cada bodega) pondría a la combinación entre los parámetros grado, pH y Acidez Total (ATOT).
