Effects of soil degradation and organic treatments on vegetative growth, yield and grape quality Organic Eprints
Tardaguila, J.; Storchi, P.; Puccioni, S.; Zombardo, A.; Tangolar, Semih; Tangolar, Serpil; Melike, A.; Kìraz, M.E.; Giffard, B.; Fulchin, E.; Schroers, H.J.; Pelengic, R.; Moreda, E.; Fernandez-Novales, J.; Costantini, E.A.C..
Delimited degraded soil areas caused by an improper land preparation before vine plantation and or management can be observed in conventional and organic European vineyards. Soil malfunctioning including: poor organic matter content, imbalanced nutritional status, altered pH, water deficiency, soil compaction and/or scarce oxygenation. The goal of the present study was to compare the effects of some agronomic strategies to restore optimal soil functionality in degraded areas in organic commercial vineyards located in five countries, and to evaluate the impact of these soil management practices on vegetative growth, yield and grape quality parameters. Grapevines located in non-degraded soils showed higher vegetative growth and yield, and lower total soluble...

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...
