Abstract
AbstractTo determine acid rain effects on nutrient solution, throughfall chemistry and nutrition of Picea abies, three years old saplings were treated with sulfuric acid (pH 2.7 and 2.4; 200 ml/tree and day) three times a day during a period of 10 days.The major effects on nutrient solution chemistry include significant increases of total acidity and sharp decreases in contents of phosphorus. Besides, the leaching of K, Ca and Mg out of the canopy clearly increases with precipitation acidity, resulting in significant lower Mg‐contents of acidic treated spruce needles.
