Effects of elevated sulphur and nitrogen deposition on the solution chemistry of Dutch forest soils are mainly manifested by increased aluminium concentrations, associated with increased concentrations of sulphate and nitrate. Critical aluminium/base cation ratios are often exceeded below 20 cm soil depth. Besides, elevated nitrogen deposition during the last decades has affected the forest nutrient status and caused large changes in vegetation. About half of the Dutch forests have absolute shortage of phosphorus and relative magnesium deficiences compared with foliar nitrogen contents. There is no evidence of a relationship between soil acidification and nutrient imbalances on the one hand and forest vitality on the other.
