Causes of soil malfunctioning in degraded areas of european and turkish vineyards

Résumé

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 lime content and poor drainage. Also nutrient unbalance or toxicity and low cation exchange capacity sporadically occurred. Since physical and hydrological limitations are hardly modifiable, especially in depth, the study underlines the difficulties to restore the fertility of degraded soils, and suggests caution in planning new vineyards.
