Abstract

Amount of nitrogen (N) dry deposition on the leaf surface of oak and cedar was compared using throughfall method and foliar rinsing method. The study was conducted at FM Tamakyuryo, located at the northeast edge of the Tama Rolling Hills, Tokyo, Japan. The throughfall method showed that the total N deposition were 19.7, 19.1, and 50.6 kg N ha-1 year-1 for open bulk deposition and total deposition in oak forest and cedar forest, respectively. The deposition of ammonium nitrogen on leaf surface were 0.29±0.38 (average ± standard deviation) and 0.75±1.06 mg N m-2 for oak and cedar, respectively, and that of nitrate nitrogen were 0.15±0.18 and 0.35±0.28 mg N m-2, respectively. Dry deposition on leaf surface was influenced by the cumulative amount of rainfall before sampling and was found to be easily washed off with high amount of precipitation within a few days.
