Abstract:
The relative contribution of foliar leaching to sulphate in throughfallis determined using radiotracer sulphate. The experiment took place in a Douglas fir forest area at Speuld, The Netherlands, from July 1993 until September 1994. The radiotracer was applied at 3-4 week intervals to the forest soil with a 4-month stop during winter. Nearly-isotopic equilibrium is obtained between total sulphur in the needles and water-extractable sulphur from the needles. The contribution of root-derived sulphur to sulphate in throughfall is calculated from the
