| Abstract:
Effects of soil physical and chemical characteristics on leaf nutritional status of three grapevine cultivars were studied during the 1988–1990 period in 8 vineyards representative of pedoclimatic conditions of a viticultural district in Northern Italy. Nutrient levels of vines were determined on leaf samples collected at fruit set and veraison. In the experimental plots penetration resistance, infiltration rate, porosity, soil water, temperature and chemical analysis of soil samples, in the 0–80 cm soil profile zone were determined in each year at fruit set and veraison. Soil physical properties and, secondly, chemical characters, affected leaf nutritional status of the vines. N nutritional status was related to soil temperature and penetrometer resistance and to the vegetative growth of the vines. Soil moisture played the highest role on P nutritional status of vines. Ca nutrition was affected by calcium carbonate content in soil and by soil temperature. Mg and K nutritional status had consistent correlations with soil physical conditions and exchangeable potassium content. | |
