CAUSES OF SOIL MALFUNCTIONING IN DEGRADED AREAS OF EUROPEAN AND TURKISH VINEYARDS Organic Eprints
Costantini, E.A.C.; Priori, S.; Giffard, B.; Fulchin, E.; Tardaguila, J.; Schroers, H.J.; Pelengic, R.; Akca, E.; Tangolar, S.; Valboa, G..
A study was carried out in nineteen vineyards of five countries, well representative of major viticultural districts, which showed areas with fertility problems, consequence of strong soil erosion occurred during either pre-planting or ordinary cultivation. The comparison between degraded and non-degraded areas highlighted that the soil features limiting water nutrition and enhancing potential water stress were the most frequent discriminant soil conditions. Low nitrogen availability was the second most important cause of soil malfunctioning, together with low organic matter content. The degradation was also reflected in the very low values of the C/N ratio, pointing to a difficulty of microbiota in synthetizing humus. Other limiting factor were excessive...

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...

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...
