Litterfall, an important component of the nutrient cycle in forest ecosystems, was measured for 9 years in young oak stands on two localities classified as beech-oak climax (Fageto-Quercetum). We estimated that about 4 Mg of dry mass per hectare fell each year. Nutrient content in the litterfall represents annually per hectare approximately 40–55 kg of nitrogen, 2–3 kg of phosphorus, 7–16 kg of potassium, 41–73 kg of calcium and 6–7 kg of magnesium. The amount of litterfall is positively correlated with stand basal area and with the death of suppressed tress with small crowns. We found a positive correlation between annual litterfall and the sum of precipitation and a negative correlation between annual litterfall and temperature in summer.Keywords:
