Aluminium toxicity has been recognized as one of the most common causes of reduced grape yields in vineyard acid soils. The main
aim of this study was to evaluate the effect of two liming materials, i.e. dolomitic lime and sugar foam, on a vineyard cultivated in an
acid soil. The effects were studied in two soil layers (0-30 and 30-60 cm), as well as on leaf nutrient contents, must quality properties
and grape yield, in an agricultural soil dedicated to Vitis vinifera L. cv. ‘Mencía’ cultivation. Data management and analysis were
performed using analysis of variance (ANOVA). As liming material, sugar foam was more efficient than dolomitic limestone because
sugar foam promoted the highest decrease in soil acidity properties at the same calcium carbonate equivalent dose. However, potassium
contents in vines organs, including leaves and berries, seemed to decrease as a consequence of liming, with a concomitant increase
in must total acidity. Soil available phosphorus also decreased as a consequence of liming, especially with sugar foam, though no effects
were observed in plants. For these reasons fertilization of this soil with K and P is recommended along with liming. Grape yields in
limed soils increased, although non-significantly, by 30%. This research has therefore provided an important opportunity to advance
in our understanding of the effects of liming on grape quality and production in acid soils.
