“…If H + ions from acids such as H 2 SO 4 and HNO 3 that are present in acid rain enter the soil, the H + ions displace, by exchange, an equivalent of nutrient cations (Ca 2+ , Mg 2+ , and K + ) from the adsorption sites of negatively charged clay particles and humic acids (Ulrich and Matzner, 1986). Thus, higher rates of acid deposition into the soil will cause loss of Ca 2+ and other nutrient cations from storage sites, gradually leading to a deficiency of nutrient cations in the forest soil and consequently symptoms of forest decline (Zottl et al, 1989;Tomlinson, 2003).…”

“…Since then, different studies have shown that nutritional imbalance was a predisposing factor of forest decline for stands situated on acid soils [12,39]. The foliar yellowing of Norway spruce associated with forest dieback was identified as a symptom of magnesium deficiency [9,37].…”

-Ten experiments were installed on acid soils in different ecoclimatic conditions of the Belgian Ardenne. Soil pH, exchangeable cations and P contents as well as foliar nutrient concentrations were monitored 1 and 3 years following the application of either (1) 3 t ha -1 of a dolomitic limestone or (2) 3 t ha -1 of a dolomitic limestone plus different amounts of P (0-800 kg natural phosphate) and/or K (0-250 kg K 2 SO 4 ). Dolomite rapidly increased Ca and Mg concentrations in the 0-10 cm soil layer and in the tree leaves. After three years, exchangeable Al was significantly lower in the first soil layer but it still represented more than 50% of the exchangeable cations. Mean pH increase in the 0-10 cm layer was less than 0.5 pH units. Dolomite alone tended to reduce mean K concentrations in the soils and/or leaves of the beech stands. The addition of potassium sulphate to dolomite generally increased the soil and foliar K contents in the spruce stands contrary to the beech stands. It also tended to increase the resaturation of the exchange complex with Ca and Mg ions. The effects of natural phosphate addition were restricted to a slight increase of P foliar concentrations. The B foliar concentrations were reduced by both treatments, whereas Zn concentrations increased significantly. The between stands variability of soil and foliage chemical properties was important but did not influence the effects of the treatments.base cation fertilization / micronutrient / Picea abies / Fagus sylvatica Résumé -Effets à l'échelle régionale de la fertilisation en cations basiques sur des peuplements d'épicéa commun et de hêtre situés sur des sols bruns acides : analyses de sols et feuilles. Dix dispositifs ont été installés dans différentes conditions écoclimatiques de l'Ardenne belge. Les cations échangeables, le pH, la concentration en P dans le sol et les teneurs foliaires en éléments ont été détermi-nés 1 et 3 ans après l'application de (1) 3 t ha -1 de dolomie ou (2) 3 t ha -1 de dolomie plus différentes doses de P (0-800 kg de phosphates naturels) et/ou de K (0-250 kg K 2 SO 4 ). La dolomie permet d'accroître rapidement la concentration en Ca et Mg dans les dix premiers cm du sol et dans les feuilles. Après 3 ans, l'Al échangeable diminue mais seulement dans la première couche de sol. Dans cette même couche, l'accroissement de pH est limité à une demi unité. La dolomie seule a tendance à réduire les teneurs en K échangeable dans le sol et les feuilles des arbres en hêtraies. L'application de K 2 SO 4 permet finalement d'accroître la concentration en K dans le sol et les feuilles des peuplements d'épicéa. De plus, ce traitement entraîne une plus grande resaturation du complexe d'échange en Ca et Mg. Les phosphates naturels augmentent légèrement les teneurs foliaires en P. Le B dans les feuilles diminue suite aux deux traitements et le Zn augmente significativement. La variabilité des propriétés chimiques des sols et des feuilles est importante entre les dispositifs expérimentaux mais n'influence pas l'effet des ...

“…Diagnostic fertilization trials have been conducted in West Germany since the early 1980's in forest stands with new type damage symptoms (Bosch and Rehfuess, 1986;H/ittl, 1985;Isermann, 1987;Kandler et al, 1987;Kaupenjohann et al, 1987;Liu, 1988;Zech, 1983;Z6ttl and H/ittl, 1986;Z6ttl et al, 1989). These indicated that acute nutritional deficiencies involving the elements Mg and K can be reduced or completely eliminated by the appropriate application of readily soluble fertilizers.…”

New types of forest damage associated with Mg (and K) deficiency can be corrected by proper fertilization using fast release Mg (and K) fertilizers or Mg limestone. Sufficient Mg and K supply provided by former fertilizer applications inhibited the appearance of typical deficiency symptoms in areas where unfertilized control trees are now characterized by yellowing. In these areas N input rates vary appreciably. Addition of N fertilizers, particularly in the form of NH4-N, can induce nutrient imbalances as was demonstrated for Mg and K. From these disorders relative growth reductions may result. However, sustained negative effects will probably only occur when large doses are applied or when atmospheric N input rates are high. Increased N uptake due to N fertilization indicated that the investigated sites were not saturated with N.Needle analysis is a very simple as well as valuable tool to characterize the nutritional status of forest trees and stands when it is carried out correctly. Nutrient ratios should receive the attention they deserve, rather than concentrate exclusively on the evaluation of absolute nutrient contents.
