Abstract in another language
A variety of different methods have been used for the determination of inorganic soil SO42- in the past, which makes it difficult to compare SO42- contents of soils.Sulfate was extracted with the four commonly used extraction solutions 0.5 M NaHCO3, 0.02 M NaH2PO4, 0.1 M NaCl and H2O from A-, Bw- and Bs-horizons of six acid forest soils. 5 g of field moist soil were percolated with a flow rate of 5 ml/h and percolations were repeated as long as SO42- was detectable in the percolate (> 0.5 mg SO4.l-1).NaCl and NaHCO3extracted highest amounts of total inorganic SO42- in A-horizons, but NaHCO3caused analytical problems. NaHCO3and NaH2PO4yielded highest amounts in B-horizons. With the exception of Bs-horizons more than 70% of the total inorganic SO42- was H2O soluble. Thus, if H2O-soluble SO42- is defined as reversibly bound, the greater part of the inorganic SO42- in the investigated acid forest soils was reversibly bound. This SO42- fraction can potentially be released, if SO42- deposition decreases.
