Effects of soil erosion on agro-ecosystem services and soil functions: A multidisciplinary study in nineteen organically farmed European and Turkish vineyards Organic Eprints
Costantini, E.A.C.; Castaldini, M.; Diago, M.P; Giffard, B.; Lagomarsino, A.; Schroers, H.J.; Priori, S.; Valboa, G.; Agnelli, A.E.; Akca, E.; D'Avino, L.; Fulchin, E.; Gagnarli, E.; Kìraz, M.E.; Knapic, M.; Pelengic, R.; Pellegrini, S.; Perria, R.; Puccioni, S.; Simoni, S.; Tangolar, S.; Tardaguila, J.; Vignozzi, N.; Zombardo, A..
This multidisciplinary research work evaluated the effects of soil erosion on grape yield and quality and on different soil functions, namely water and nutrient supply, carbon sequestration, organic matter recycling, and soil biodiversity, with the aim to understand the causes of soil malfunctioning and work out a proper strategy of soil remediation. Degraded areas in nineteen organically farmed European and Turkish vineyards resulted in producing significantly lower amounts of grapes and excessive concentrations of sugar. Plants suffered from decreased water nutrition, due to shallower rooting depth, compaction, and reduced available water capacity, lower chemical fertility, as total nitrogen and cation exchange capacity, and higher concentration of...

Monitoring and mapping soil functionality in degraded areas of organic European vineyards Organic Eprints
Priori, S.; Tardaguila, J.; Diago, M.P; Aquino, A.; D'Avino, L.; Lagomarsino, A.; Pellegrini, S.; Valboa, G.; Costantini, E.A.C..
Soil malfunctioning, caused by an improper land preparation before vine plantation and/or management, is a common problem in European vineyards. Soil malfunctioning can include: reduced contribution of the soil fauna, poor organic matter content, imbalance nutritional status, altered pH, water deficiency, soil compaction and/or scarce oxygenation. To address these problems, ReSolVe, a transnational European research project, aimed at testing the effects of selected agronomic strategies for restoring optimal soil functionality in degraded areas within organic vineyard. The project involves 8 research groups in 6 different EU countries (Italy, Spain, France, Sweden, Slovenia, and Turkey) with experts from several disciplines including soil science, ecology,...

USE OF NON-INVASIVE RGB IMAGING TO ASSESS THE CANOPY STATUS IN ORGANIC VITICULTURE Organic Eprints
Diago, M.P; Fernandez-Novales, J.; Palacios, F.; Moreda, E.; Tardaguila, J..
In organic viticulture, canopy features such as leaf area, canopy porosity and fruit exposure are critical due their impact on fungal disease incidence and grape composition. An adequate and accurate assessment of the canopy status is the first step towards appropriate and effective grapevine canopy management, therefore an easy, non-invasive, robust method to evaluate the main features of a grapevine canopy is needed. In this work a protocol for canopy status assessment based on non-invasive RGB imaging is presented and used to ascertain differences in the canopy status of grapevines grown under different degraded and non-degraded soil conditions. RGB images were processed using a classification algorithm based on the Mahalanobis distance, and then the...

Vineyard water status assessment using on-the-go thermal imaging and machine learning Organic Eprints
Gutiérrez, S.; Diago, M.P; Fernandez-Novales, J.; Tardaguila, J..
The high impact of irrigation in crop quality and yield in grapevine makes the development of plant water status monitoring systems an essential issue in the context of sustainable viticulture. This study presents an on-the-go approach for the estimation of vineyard water status using thermal imaging and machine learning. The experiments were conducted during seven different weeks from July to September in season 2016. A thermal camera was embedded on an all-terrain vehicle moving at 5 km/h to take on-the-go thermal images of the vineyard canopy at 1.2 m of distance and 1.0 m from the ground. The two sides of the canopy were measured for the development of side-specific and global models. Stem water potential was acquired and used as reference method....
