| Abstract: | In order to quantify the atmospheric nitrate and sulfate deposition and to investigate factors related to the variability of deposition during 1983 and 1984, precipitation samples from five different meteorological stations in Schleswig-Holstein (Northern Germany) were collected in weekly intervals, using the bulk-sample method. The average element depositions in kg ha−1 a−1 were: 20 for S and 5.5 for N in List (North Sea Island Sylt) and Schleswig, 12 for S and 4.7 for N in Kiel, 16 for S and 4.3 for N in Luebeck and 18 for S and 4.2 for N in Quickborn near Hamburg.N and S concentrations showed a close relationship to the amount of precipitation and the following functions for the estimation of nitrate-N and sulfate-S deposition in Schleswig-Holstein could be derived: (x = precipitation in mm a−1, y = N or S deposition in kg ha−1 a−1) NO3-N: y = 0.003x + 2.29; SO4−S: y = 0.014x + 4.71. According to these relationships most of the element deposition occurred during atmospheric conditions of predominating winds from the west. Especially in the case of S, atmospheric deposition is the only external source of S supply for plants on many agricultural soils. Sometimes the low sulfur input is not sufficient to cover the requirements of agricultural crops in Schleswig-Holstein. Due to the negative S balance in many soils, future increase of S deficiency is expected. |
