Litter decomposition is the most important way of nutrient entering to soil and soil nutrient availability is highly related to dynamics of nutrients and litter decomposition in the forest ecosystems. This study aimed to evaluate the dynamics of nutrients and litter decomposition in the northern Zagros forests using litterbag technique for 180 days in the Khul Hoare forests located in Baneh city. The litter bags were collected at intervals of 30, 60, 120 and 180 days and the rate of leaf litter decomposition and chemical compounds such as nitrogen, carbon, phosphorus, potassium and calcium were measured. The results showed there was no significant correlation between the rate of decomposition and the initial composition of nutrients and also C: N and C: P ratios. Due to the qualification of leaf litter based on the amount of nitrogen in this study, the average amount of nitrogen in Quercus libani was 1.37%. So Lebanon oak can be classified in the average group and it can be considered as a soil improver species. In the studied litter, phosphorus and nitrogen had a similar performance and their concentration increased over time (7.27 and 30.38 mg/g respectively). While concentration of elements such as calcium, potassium and magnesium was decreased. The nutrient concentration of Quercus libani leaf litter was Ca>N>P>K> Mg.
