We sampled soil water by means of ceramic cups placed at three different depths (20, 40, and 60 cm) in a vineyard in order to observe the influence of dolomite application on the evolution of pH and on the nitrate and aluminium contents in soil solution. Liming tended to increase the nitrate content, especially in depth. However, its influence did not seem very important, whereas it reduced significantly the aluminium content in soil solution. Applying 30 t/ha of dolomitic lime reduced the aluminium content to a constant and very low level during the whole year, while the control plot was subject to strong variations, probably linked to the acidifying effect of the fertilisers.
